How to Clean & Care for USM Haller: The Complete Powder-Coated Furniture Guide
Identify the surface before choosing a cleaner. USM's care instructions distinguish materials; they do not certify cleaners or replacement parts for every brand.

In brief: identify the manufacturer and surface before cleaning modular furniture. USM's January 2026 care booklet distinguishes Haller and table surfaces from Soft Panels, Privacy Panels and Inos. Its glass-cleaner example appears under the latter group, not as blanket permission for every steel panel. A compatible-looking Klackjoy part needs the care instructions for its own finish.
Published by Klackjoy, an independent manufacturer, not a conservation service or independent testing laboratory. The official USM document and our own published material and warranty information were checked on 16 October 2026 (Asia/Shanghai). This guide does not establish chemical compatibility for an unidentified coating or prescribe a structural repair.
First identify the surface
Separate a coated steel panel, chrome-plated tube, plated connector, glass, wood and fabric or leather finish. The underlying metal and the exposed finish are not the same specification. A steel panel's cleaning method does not automatically apply to a nearby glass insert, veneer or plated joint.
Klackjoy describes powder-coated steel panels, chrome-plated stainless-steel tubes and chrome-plated brass connectors in its materials information. That identifies our published components; it does not transfer USM's care approval to them. Record the selected material, finish, order information and any manufacturer instructions before treating an unfamiliar mark.
What USM's own instructions actually say
USM's Cleaning and care booklet, page 4, gives these instructions for Haller and table surfaces:
- Use a soft cloth for dry cleaning.
- For wet cleaning, use a soft cloth or chamois dampened with water and wrung out.
- For heavier dirt, use a diluted neutral cleaning fluid; the document specifies pH below 9.
- Do not leave the table surface damp for a long time. Avoid abrasive agents and sponges, abrasive microfiber cloths, and solvents.
The word neutral matters: the pH condition is not permission to use any acidic product below that number. Nor does the booklet say every microfiber cloth is suitable. Follow the current product instructions rather than choosing a cleaner by a marketing label alone.
The document is linked from USM's current downloads page. The older indexed 2021 PDF URL returned 404 during this check; search-result summaries were not used as the cleaning authority.
Glass cleaner: keep the product heading attached
On the same page, gentle cleaner, with glass cleaner as an example, appears under USM Haller Soft Panels, USM Privacy Panels and USM Inos for more stubborn dirt. That paragraph also calls for light rubbing.
Do not detach that example from its heading and turn it into a universal recommendation for powder-coated steel or plated connectors. A claim such as “ammonia-free” does not by itself establish the whole formulation's suitability. If the surface or cleaner is unidentified, obtain the appropriate manufacturer's guidance before application.
Fingerprints, spills and coated versus chrome parts
For an original USM surface covered by the booklet, start with its stated gentle method rather than polishing harder. For another manufacturer's panel or tube, check that component's instructions first. Keep liquids away from openings and fittings when cleaning as directed; do not turn a general care article into permission to soak joints or mechanisms.
After a spill, identify the liquid and material, follow the relevant care instructions and avoid leaving an affected surface wet. If there is staining, coating damage, lifting edges or an affected mechanism, document it and ask the supplier what treatment is appropriate. This guide does not promise stain removal or approve a particular household cleaner for every finish.
Coated steel and chrome plating have different exposed surfaces. Do not choose a metal polish merely because the underlying component is metal, or assume a cloth suitable for one surface cannot abrade another.
Scratches, replacement and warranty
Distinguish a removable mark from a scratch through the coating, damaged plating or a damaged structural part. Do not assume touch-up paint restores the original appearance, corrosion protection or warranty status. Ask the supplier about the exact finish and repair or replacement route before sanding, polishing or repainting.
A replacement front requires its dimensions, retained fittings, opening direction and supplier's confirmation, not just a similar color. Use the panel-fit checklist and reconfiguration guide. Modularity does not prove every replacement panel fits every existing cabinet.
Klackjoy's 10-year structural warranty has a stated scope and exclusions. Do not treat a structural warranty as automatic cover for scratches, cleaner damage, surfaces or every mixed-brand repair. No like-for-like delivered replacement quotations are supplied here, so no fixed saving is established.
A useful care record
Keep the manufacturer, material and finish, the care-document version, a description or photograph of the affected area, the cleaner label if one was used, and the supplier's recommended next step. Exclude personal addresses and order credentials from any public record. This helps distinguish a cleaning question from a finish or hardware replacement task.
Frequently Asked Questions
How do you clean USM Haller furniture?
Identify the manufacturer and surface first. For original USM Haller and table surfaces, USM's January 2026 care booklet specifies a soft dry cloth, or a water-dampened, well-wrung soft cloth or chamois. For heavier dirt it specifies diluted neutral cleaning fluid with pH below 9; avoid abrasives and solvents. Do not transfer these instructions automatically to another manufacturer's finish.
Can I use glass cleaner on USM Haller?
Do not assume every glass cleaner is approved for every panel. In USM's care booklet, the glass-cleaner example sits under Soft Panels, Privacy Panels and Inos, not as general permission for Haller steel surfaces. Check the instructions for the actual surface and cleaner formulation; an ammonia-free label alone is not proof of suitability.
How do I remove fingerprints from USM Haller?
For an original USM surface covered by its booklet, use its stated gentle cleaning method. For another manufacturer's surface, confirm its own care guidance first. Avoid abrasive rubbing or unapproved polish, and ask the supplier about persistent marks rather than promising that a cleaner will remove every fingerprint or stain.
How do I fix a scratch on USM Haller?
First distinguish a surface mark from damaged coating, plating or structure. Obtain the supplier's guidance before touching up, sanding or replacing anything. A replacement panel needs confirmed dimensions and fittings; no universal fit, fixed replacement saving or warranty coverage for scratches is established here.
How do I care for the chrome connectors?
Identify the manufacturer and plating before treatment. USM's Haller care guidance calls for gentle cleaning and excludes abrasives and solvents; do not assume a metal polish is approved just because the connector is metal. Klackjoy's chrome-plated brass connector specification is an identification fact, not a chemical-compatibility or repair certificate.
