✓ Chrome fittings (with care)

Taps, showerheads, and chrome hardware are fine with a light touch. Spray lightly (don't soak), wipe with a soft Koh cloth, rinse or wipe again with clean water if needed, then dry to avoid water spots. Don't let it dwell on the surface, skip abrasive pads, and avoid damaged or peeling chrome.

Light spray Wipe and dry No abrasives

✓ Soft furnishings (spot test)

Carpets, rugs, upholstery, and leather for spot-cleaning. Always spot test in an inconspicuous area first. Avoid wool and untreated natural fibres.

What surfaces should I avoid using Universal Cleaner on?

Koh Universal Cleaner is alkaline (pH 12.5) and isn't suitable for soft metals such as zinc, copper, and brass which can discolour or tarnish; raw or untreated aluminium which can oxidise or pit; aftermarket window tints and films which can peel or cloud; and glass surfaces with factory-applied or aftermarket easy-clean coatings (such as ShowerGuard, Diamon-Fusion, ClearShield, EnduroShield, or similar hydrophobic glass treatments), which can break down with alkaline cleaners. These materials react with alkaline cleaners generally, not just Koh. For wool and untreated natural fibres, use a different cleaner. When in doubt, spot test in an inconspicuous area before cleaning the full surface.

How do I spot test Universal Cleaner on a surface?

To spot test Koh Universal Cleaner on an unknown surface: pick a hidden spot like the back of a cabinet, underside of a chair, hem of upholstery, or a corner that won't show. Apply a small amount of undiluted Universal Cleaner to a Koh cloth and wipe gently. Wait a few minutes and check for discolouration, etching, or any change to the surface before cleaning the full area. If the surface looks unchanged, you're safe to proceed. If you notice any change, don't continue and try a different cleaner. Universal Cleaner is used undiluted, so the spot test reflects the actual product strength you'll be using.
