How to Clean & Care for USM Haller (Complete Guide)

USM Haller is cleaned with a soft, damp microfiber cloth and warm water — nothing more aggressive is needed for everyday care. The powder-coated steel and chrome ball connectors are durable, but the wrong products can dull the finish or scratch it permanently. This guide covers everyday cleaning, fingerprints and grease, scratch repair, chrome connector care, and what never to use.

How do you clean USM Haller furniture?

You clean USM Haller by wiping the powder-coated surfaces with a soft microfiber cloth dampened in warm water, then drying with a clean dry cloth. For everyday dust and marks this is all you need. Work in sections, rinse the cloth often, and avoid leaving standing water on horizontal surfaces or in the gaps around the connectors.

For anything stickier, add a small amount of mild detergent (a drop of dish soap in warm water), wipe, then go over the surface again with a clean damp cloth to remove residue. Always dry afterward — trapped moisture is the main long-term enemy of any powder-coated steel.

Can I use glass cleaner on USM Haller?

Yes, a standard ammonia-free glass cleaner can be used on USM Haller powder-coated panels to remove fingerprints and light grease. Spray the cleaner onto the cloth rather than directly onto the furniture, wipe the marked area, and buff dry. Test on a hidden spot first if you are unsure, and never use cleaners containing ammonia, bleach, acetone or other solvents.

How do I remove fingerprints and grease marks?

Fingerprints and grease are removed with a microfiber cloth and either mild detergent or an ammonia-free glass cleaner. Smooth, glossy USM finishes show fingerprints more than matte ones, especially in darker colours. A quick wipe with a barely-damp cloth followed by a dry buff usually clears them without leaving streaks.

For stubborn grease — common on kitchen-area units — use warm water with a drop of dish soap, wipe gently, then rinse the cloth and remove all residue before drying.

What should I never use on USM Haller?

Never use abrasive pads, scouring powders, bleach, ammonia, acetone, paint thinner, or steam cleaners on USM Haller. Abrasives scratch the powder coating; bleach and ammonia can discolour it; solvents like acetone can soften or strip the finish; and steam forces moisture into the connector joints. Stick to soft cloths, warm water, mild detergent, and at most an ammonia-free glass cleaner.

No abrasive sponges, steel wool, or scouring powder
No bleach, ammonia, or all-purpose sprays containing them
No acetone, white spirit, paint thinner or other solvents
No steam cleaners or pressure washing

How do I care for the chrome ball connectors?

The chrome ball connectors are cleaned with a soft damp cloth and dried immediately to prevent water spots. Each connector is a 25mm chrome-plated brass ball with an M8 thread — the same connector standard Klackjoy uses. Wipe them with the same warm water and microfiber routine as the panels, and dry them promptly; do not use metal polish or abrasive chrome cleaners, which can leave fine scratches on the plating.

The chrome-plated steel tubes that link the connectors are cleaned the same way: damp cloth, then dry.

What about scratches and damage?

A scratched panel does not mean replacing the whole unit — because USM Haller is modular, you replace the single affected panel and keep the rest. This is the maintenance advantage of a modular system over a one-piece cabinet: damage is contained to one part. Light surface marks can sometimes be reduced with a colour-matched touch-up, but a deep scratch through the powder coating is best solved by swapping the panel.

This is also where a compatible alternative helps. Klackjoy panels use the same powder-coated steel standard and are physically compatible with genuine USM Haller (owner-confirmed), so you can replace a damaged USM panel — or extend the unit 1:1 — for roughly 60–70% less than USM, with a 10-year structural warranty. If you are already rethinking the layout while you are at it, see how to reconfigure a USM Haller unit.

Frequently Asked Questions

How do you clean USM Haller furniture?

You clean USM Haller by wiping the powder-coated surfaces with a soft microfiber cloth dampened in warm water, then drying with a clean dry cloth. For sticky marks add a drop of mild detergent, wipe, then go over the surface with a clean damp cloth and dry it — trapped moisture is the main long-term enemy of powder-coated steel.

Can I use glass cleaner on USM Haller?

Yes, a standard ammonia-free glass cleaner can be used on USM Haller powder-coated panels to remove fingerprints and light grease. Spray the cleaner onto the cloth rather than the furniture, wipe, and buff dry, and never use cleaners containing ammonia, bleach, acetone or other solvents.

How do I remove fingerprints from USM Haller?

Fingerprints are removed with a microfiber cloth and either mild detergent or an ammonia-free glass cleaner. Glossy and darker USM finishes show fingerprints more, so a quick wipe with a barely-damp cloth followed by a dry buff usually clears them without leaving streaks.

How do I fix a scratch on USM Haller?

Because USM Haller is modular, a scratched panel is fixed by replacing that single panel rather than the whole unit. Light marks can sometimes be reduced with a colour-matched touch-up, but a deep scratch through the powder coating is best solved by swapping the panel, and compatible Klackjoy panels cost roughly 60–70% less than USM.

How do I care for the chrome connectors?

The chrome ball connectors are cleaned with a soft damp cloth and dried immediately to prevent water spots. Each is a 25mm chrome-plated brass ball with an M8 thread; avoid metal polish or abrasive chrome cleaners, which can leave fine scratches on the plating.
