The tops of the steps have been cleaned, and the grooves are less dark, but the vertical surfaces remain dirty. This discrepancy highlights a common misunderstanding: <strong>Cleaning the tread is not the same as cleaning all the steps<\/strong>.<\/p>\n<p>For a site manager, there\u2019s more to this than meets the eye. Cleaning escalator steps and risers must take into account their geometry, the mechanical parts located beneath them, and what happens to the moisture used. At KHOMCLEAN, our recommendation is clear: precisely define the surfaces to be treated, use equipment compatible with the escalator, and recover liquids as close as possible to the brushing area. Here are the points to consider before approving a cleaning operation.<\/p>\n<h3 id=\"ce-qu-il-faut-retenir\">Key Takeaways<\/h3>\n<ul>\n<li>\n<p>We\u2019re clearing up a major misconception: cleaning the tread surface is not the same as a thorough cleaning<\/p>\n<\/li>\n<li>\n<p>The article explains why dirt on the risers poses a technical challenge and how a moisture extraction system protects the integrity of the escalator<\/p>\n<\/li>\n<li>\n<p>the distinction that your service providers are unaware of<\/p>\n<\/li>\n<li>\n<p>Compare the different options before making a decision.<\/p>\n<\/li>\n<\/ul>\n<h2 id=\"nettoyage-de-surface-vs-entretien-integral-la-distinction-que-vos-prestataires-ignorent\">Surface Cleaning vs. Comprehensive Cleaning: The Difference Your Service Providers Don't Know About<\/h2>\n<p>Does your service actually cover both sides of each step? This question deserves more than just a line saying \u00abescalator cleaning\u00bb on a report. A machine designed to work on a horizontal surface does not necessarily clean the vertical side, even when the result visible from the entrance appears satisfactory.<\/p>\n<p><img decoding=\"async\" class=\"max-w-full h-auto rounded-md\" src=\"https:\/\/nghaeknymynesecnqcmd.supabase.co\/storage\/v1\/object\/public\/article-images\/article-1789725448149-nettoyage-marches-et-contremarches-d-escalator-l-expertise-technique.png\" alt=\"Escalator Step and Risers Cleaning: Technical Expertise\"><\/p>\n<p>Let's go over the terms again. The <strong>walk<\/strong> commonly refers to the part of the footrest that the passenger uses for support. Its upper surface, called the tread, has grooves. The <strong>stair riser<\/strong> is its nearly vertical face, visible between two successive levels on the sloped section. On an escalator, these components move, and their relative positions change as they approach the landings. Therefore, maintenance is not performed in the same way as on a fixed staircase.<\/p>\n<p>The tread surface is directly exposed to shoe marks, dust, and debris brought in from outside. Professional cleaning must remove deposits from the grooves\u2014not just lighten their edges. The risers, on the other hand, require a cleaning method suited to their profile and orientation. <strong>Equipment that performs well on top isn't necessarily effective at the front.<\/strong><\/p>\n<p>In a B2B escalator maintenance specification, identify three distinct areas:<\/p>\n<ul>\n<li>\n<p><strong>Routine cleaning of accessible surfaces<\/strong>, including waste removal and cleaning services as specified in the contract.<\/p>\n<\/li>\n<li>\n<p><strong>Thorough cleaning of steps and risers<\/strong>, using a method explicitly tailored to both surfaces.<\/p>\n<\/li>\n<li>\n<p><strong>Technical Maintenance<\/strong>, which covers, among other things, inspections, adjustments, and maintenance of mechanical components and safety devices.<\/p>\n<\/li>\n<\/ul>\n<p>This distinction prevents misleading claims: a thorough cleaning is not the same as a service on the equipment. The drive chain, guides, and safety devices are the responsibility of the maintenance technician, depending on the scope of their work. Any malfunction detected during cleaning must be reported to the maintenance technician; it must not be corrected on the spot by an unauthorized team.<\/p>\n<p>In terms of standards, NF EN 115-1 addresses the safety of the construction and installation of escalators and moving walkways. NF EN 115-2 concerns the improvement of safety in existing installations. However, a reference to an escalator safety standard does not replace the manufacturer\u2019s instructions or site-specific procedures. Above all, insist on a written scope of work, exclusions, and observable acceptance criteria: clear grooves, treated vertical surfaces, absence of residue, and a documented final condition.<\/p>\n<h2 id=\"l-accumulation-de-salete-sur-les-contremarches-pourquoi-est-ce-si-complexe\">Dirt buildup on stair risers: Why is it so complicated?<\/h2>\n<p>The difficulty stems primarily from the geometry. An escalator riser is not a smooth surface that can be wiped from top to bottom: its grooved profile, its possible curvature, and its proximity to the adjacent step limit access for cleaning tools. Some brushes reach the raised areas but fail to properly clean the grooves. Visually, the surface appears cleaner; however, the embedded dirt in the grooves remains.<\/p>\n<p>Not all deposits are the same. In a shopping center that opens onto a parking lot, mineral particles can mix with greasy residue brought in on shoes. Near a food court, food splatters add a sticky component. The friction from shoes and the gradual buildup of dust eventually form marks that are difficult to remove with a quick, superficial wipe.<\/p>\n<p>Given these technical constraints, increasing the amount of water is a bad idea. Water laden with dirt can seep into the gaps instead of being collected. A brush that\u2019s too abrasive can also damage certain surfaces or marking elements. <strong>The proper treatment depends on the material, the profile, and the manufacturer's instructions<\/strong>, not just based on the apparent level of fouling.<\/p>\n<p>The accessibility of the riser therefore determines the choice of equipment and the organization of the job site. It is essential to verify that the equipment can actually reach the target area without coming into damaging contact with adjacent components. When it is necessary to reposition the steps, this must be done according to a controlled procedure under the supervision of authorized personnel. No improvised manual access near moving parts has any place in an industrial cleaning service.<\/p>\n<p>The regulatory framework also warrants further clarification. The rules governing the height of risers on a fixed staircase do not apply directly to an escalator. The same caution applies to high-contrast risers: the accessibility requirements applicable to fixed staircases do not, on their own, require modifications to escalator steps. Adding a strip, paint, or covering without approval may interfere with the escalator\u2019s operation or obscure markings provided by the manufacturer.<\/p>\n<p>To inspect the work, look at the risers from an angle that allows you to see their grooves, while standing in a safe position. Before-and-after photographs taken under comparable conditions help distinguish genuine cleaning from a mere change in sheen. If a mark remains, determine whether it is still a deposit or a change in the material itself. Scrubbing harder does not always improve the result.<\/p>\n<h2 id=\"technologie-d-aspiration-et-gestion-de-l-humidite-la-recommandation-khomclean\">Vacuum Technology and Moisture Management: The KHOMCLEAN Recommendation<\/h2>\n<p>A small amount of moisture left in a groove may simply shift the problem rather than solve it. The liquid has loosened the dirt, but if it isn\u2019t collected, it remains laden with particles and cleaning solution. As it dries, it can leave a film; as it runs off, it can reach areas that were not meant to get wet.<\/p>\n<p>Our recommendation at KHOMCLEAN is based on a simple combination: <strong>Controlled application of the solution, appropriate mechanical action, and moisture extraction as close as possible to the treated area<\/strong>. The brush removes deposits, while the collection system limits the spread of the dirty liquid. The goal is not to soak the surface and then let it dry for a long time. It is to use only the moisture necessary for the chosen process and to remove it as work progresses.<\/p>\n<p>The term \u00ableak-free system\u00bb must correspond to performance verified under on-site conditions. It does not imply either a total absence of moisture or an absolute guarantee against any infiltration. Effectiveness depends, in particular, on the fit of the cleaning head, the applied flow rate, the condition of the brushes, the water suction system, and the geometry of the steps. A powerful suction system on paper alone cannot compensate for a poorly fitted cleaning head.<\/p>\n<p>A thorough method includes several checks:<\/p>\n<ol>\n<li>\n<p><strong>Check Compatibility<\/strong> the machine, brushes, and cleaning solution, based on the escalator model and the manufacturer's recommendations.<\/p>\n<\/li>\n<li>\n<p><strong>Ensuring a Safe Operation<\/strong> through signage, access restrictions, and appropriate shutdown or lockout procedures. Any operation necessary for a specialized process must be expressly provided for and regulated.<\/p>\n<\/li>\n<li>\n<p><strong>Test a representative area<\/strong> to verify the result, ensure that the liquid has been collected, and confirm that there is no contamination.<\/p>\n<\/li>\n<li>\n<p><strong>Monitor Recovery<\/strong> : operational suction, available tank, no leaks, and control of wet residues.<\/p>\n<\/li>\n<li>\n<p><strong>Check the final condition<\/strong> before making it available again in accordance with the site's procedure, and reporting any issues to the maintainer.<\/p>\n<\/li>\n<\/ol>\n<p>This humidity control helps limit unwanted exposure of components located under the steps, particularly the drive chain and, depending on the configuration, electrical equipment. It does not, however, eliminate the need for the protective measures and restrictions specified by the manufacturer.<\/p>\n<p>Cleaning the escalator is therefore part of a preventive maintenance program: it reduces the buildup of deposits and makes it easier to spot certain visible abnormalities. It does not certify the mechanical condition of the escalator. The frequency of cleaning should be based on the actual usage of the site, the nature of the dirt, and the results observed, rather than on a uniform schedule for all units.<\/p>\n<h2 id=\"conclusion\">Conclusion<\/h2>\n<p>Specify a method before specifying a frequency. This is the best way to refine your specifications: an additional pass over a horizontal surface will not correct a problem with the treatment of the risers. The requirement must be defined in terms of surfaces, the expected level of results, and the conditions under which the work will be performed.<\/p>\n<p>For your next discussion with a service provider, start by identifying the specific piece of equipment and reviewing its history. Which areas remain dirty after the usual cleaning routines? What products have already been used? Does the manufacturer impose any specific restrictions? The answers will help you define a useful course of action without promising to remove a mark that is actually the result of wear and tear or damage to the surface.<\/p>\n<p>The preparatory document can be brief. However, it must include the information needed to avoid unforeseen circumstances:<\/p>\n<ul>\n<li>\n<p>The brand, model, and available instructions for the device in question.<\/p>\n<\/li>\n<li>\n<p>Views of the surfaces to be treated, particularly the vertical faces and the areas with the heaviest load.<\/p>\n<\/li>\n<li>\n<p>The time frame for intervention and the procedures for restricting public access.<\/p>\n<\/li>\n<li>\n<p>The maintainer's contact information and the division of responsibilities for the necessary operations.<\/p>\n<\/li>\n<li>\n<p>The agreed-upon checkpoints for accepting the result and organizing the return to service.<\/p>\n<\/li>\n<\/ul>\n<p><strong>Quality depends just as much on preparation as it does on brushing.<\/strong> A team must know what to work on, what not to touch, and when to stop working and contact the technical manager. This discipline protects the facility and makes the service more predictable for site operations.<\/p>\n<p>The inspection should be conducted with the same level of thoroughness. Document the treated areas, any reservations, and any defects observed. This tracking provides a concrete basis for adjusting future treatments and prevents you from repeating, month after month, a poorly targeted operation.<\/p>\n<p>Would you like to learn more about cleaning the steps and risers on your escalators? <strong>Contact KHOMCLEAN to discuss your needs and the constraints of your site.<\/strong> The goal: to develop a clear service offering that is compatible with your maintenance organization and focused on verifiable results, not just the impression of cleanliness.<\/p>\n<h2 id=\"questions-frequentes\">Frequently Asked Questions<\/h2>\n<\/p>\n<details class=\"faq-item\">\n<summary>If the tops of the steps on an escalator are clean, does that mean the entire escalator has been cleaned?<\/summary>\n<p>No: The tread, where passengers place their feet, and the risers, which form the vertical sides, each require their own specific cleaning method. A machine that is effective on the tread may leave the vertical sides dirty. Even a thorough cleaning of both surfaces is no substitute for technical maintenance of the mechanisms and safety devices.<\/p>\n<\/details>\n<details class=\"faq-item\">\n<summary>Why are the steps on an escalator so hard to clean?<\/summary>\n<p>Their grooved surface, any curvature, and the proximity of the adjacent step limit the brushes\u2019 access, so they can clean the raised areas but cannot reach the recesses. Dust mixed with grease or food residue also forms deposits that are difficult to remove. Adding more water may cause the dirt to migrate into the crevices, while brushing too aggressively can damage certain floor coverings.<\/p>\n<\/details>\n<details class=\"faq-item\">\n<summary>What should you tell the service provider before having the steps and risers cleaned?<\/summary>\n<p>Request a written scope of work that specifies the areas to be treated, exclusions, and acceptance criteria, as well as a method compatible with the escalator model and the manufacturer\u2019s instructions. Provide the unit\u2019s model number, photos of the soiled areas, and the scheduled service window. Also specify the procedures for restricting public access and the responsibilities for the necessary operations, including the maintenance provider\u2019s contact information.<\/p>\n<\/details>\n<details class=\"faq-item\">\n<summary>How does moisture extraction protect the components under the steps?<\/summary>\n<p>Suction performed as close as possible to the brushing action captures the dirt-laden liquid before it can seep into crevices or leave a film as it dries. Combined with a controlled supply of cleaning solution, this limits unwanted exposure of components located under the steps. However, a system advertised as \u00abdrip-free\u00bb does not guarantee the absolute absence of seepage: its effectiveness depends, in particular, on the proper adjustment of the head and the suction circuit.<\/p>\n<\/details>\n<details class=\"faq-item\">\n<summary>How can you verify that the stair risers have actually been cleaned?<\/summary>\n<p>Once the device is secured, examine the risers from an angle that allows you to see the grooves, rather than relying on their shine as viewed from the landing. Before-and-after photos, taken under comparable conditions, help verify that the machine has been cleaned. If a mark persists, you must distinguish between a remaining deposit and material damage before continuing to clean it further.<\/p>\n<\/details>\n<details class=\"faq-item\">\n<summary>How often should the steps and risers of an escalator be cleaned?<\/summary>\n<p>The frequency depends on the actual use of the site, the nature of the dirt, and the results observed after cleaning, rather than on a uniform schedule for all units. Before adding additional cleaning passes, verify that the method effectively reaches the risers: cleaning the top surface more frequently will not correct a poorly treated vertical surface. Monitoring the cleaned areas and the areas that still need attention then allows you to adjust the cleaning schedule accordingly.<\/p>\n<\/details>","protected":false},"excerpt":{"rendered":"<p>Escalator Steps and Risers: The Secrets to Professional CleaningTable of ContentsSurface Cleaning vs. Comprehensive Maintenance: The Distinction Your Service Providers Don\u2019t Know AboutDirt Buildup on the\u2026<\/p>","protected":false},"author":1,"featured_media":25099275,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[1],"tags":[],"dipi_cpt_category":[],"class_list":["post-25099276","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-non-classe"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
