What surfaces can I use Universal Cleaner on?

Koh Universal Cleaner is a no-rinse multipurpose cleaner that works on 20+ household surfaces. In the kitchen: benchtops, splashbacks, ovens, stovetops including induction cooktops, rangehoods, sinks, cabinet faces and the inside of the fridge. In the bathroom: tiles, grout, showers, bathtubs, sinks, tapware, vanity tops, mirrors and toilet exteriors. On glass and mirrors: windows, shower screens, glass tabletops and polished surfaces, finished with a Koh glass cloth. On floors: sealed timber, laminate, tile, vinyl and sealed stone. For oiled or waxed timber, fill your Spray Mop with plain water instead. On laminates and synthetic surfaces: laminate benchtops, melamine cabinetry, acrylic and sealed composite. On chrome fittings with a light spray and a wipe-and-dry technique. On carpets, rugs, upholstery and leather for spot-cleaning, after a spot test. It is used undiluted from the atomiser or the spray mop.

✓ Kitchen

Benchtops, splashbacks, ovens, stovetops including induction cooktops, rangehoods, sinks, cabinet faces and the inside of the fridge. The alkaline formulation is what cuts through cooking grease and organic matter, making it easier to clean.

Cuts grease Suits induction tops No-rinse

✓ Bathroom

Tiles, grout, showers, bathtubs, sinks, tapware, vanity tops, mirrors and toilet exteriors. Lifts soap scum and mineral build-up off the surface so it wipes away.

Soap scum Works on sealed grout

✓ Glass and mirrors

Windows, mirrors, shower screens, glass tabletops and polished surfaces. Universal Cleaner is made with laboratory grade purified water. Use a Koh glass cloth and buff dry for a clear finish.

Streak-free finish Glass and mirrors

✓ Floors

Sealed timber, laminate, tile, vinyl, sealed stone and most sealed floor surfaces. For oiled or waxed timber, fill your Spray Mop with plain water instead. Pair it with Spray Mop for a no-bucket mop.

Sealed timber Laminate Sealed stone

✓ Laminates and synthetic surfaces

Laminate benchtops, melamine cabinetry, acrylic, sealed composite and most synthetic surfaces around the home. Spray, wipe, and wipe it off rather than letting it sit.

Laminate benchtops Melamine Acrylic

✓ Chrome fittings, with a light touch

Taps, showerheads and chrome hardware are fine with care. Spray lightly rather than soaking, wipe with a soft Koh cloth, wipe again with clean water if needed, then dry to avoid water spots. Don't let it dwell, skip abrasive pads, and leave damaged or peeling chrome alone.

Light spray Wipe and dry No abrasives

✓ Soft furnishings, after a spot test

Carpets, rugs, upholstery and leather for spot-cleaning. Always spot test in an inconspicuous area first. Wool and untreated protein fibres need a different cleaner.

What surfaces should I avoid using Universal Cleaner on?

Koh Universal Cleaner is an alkaline formulation, and that sets its limits. It is not suitable for soft metals such as zinc, copper and brass, which can discolour or tarnish. Not for raw or untreated aluminium, which can oxidise or pit. Not for aftermarket window tints and films, which can peel or cloud. Not for glass carrying a protective coating such as Enduroshield, which alkaline cleaners can break down. Wool and untreated protein fibres need a different cleaner. As a general rule, avoid surfaces susceptible to higher alkaline solutions. Extended contact is what causes blemishing, so wipe the product off rather than leaving it to sit. When you are unsure, spot test in an inconspicuous area and check for discolouration or blemishing or any change to the surface.

Extended contact is what causes blemishing, so wipe the product off rather than leaving it to sit. These materials react to alkaline cleaners generally rather than to Koh specifically, so the same caution applies to any alkaline product you reach for.

How do I spot test Universal Cleaner on a surface?

To spot test Koh Universal Cleaner on an unknown surface, pick a hidden spot such as the back of a cabinet, the underside of a chair, the hem of upholstery or a corner that will not show. Apply a small amount of undiluted Universal Cleaner to a Koh cloth and wipe gently. Wait a few minutes, then check for discolouration or blemishing or any change to the surface before you clean the full area. If nothing has changed, go ahead. If anything has, stop and use a different cleaner. Universal Cleaner is used undiluted, so the spot test reflects the actual strength you will be cleaning with.
