What surfaces can I use Universal Cleaner on?

Universal Cleaner works on most hard surfaces around the home: kitchen benchtops, splashbacks, ovens, stovetops (including induction), bathroom tiles and grout, showers, bathtubs, sinks, tapware, glass and mirrors, and most sealed floor types (hardwood, laminate, tile, sealed stone). It also handles spot-cleaning on carpets, rugs, upholstery, and leather, but always spot test these first.

✓ 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?

Universal Cleaner is alkaline (pH 12.5), which means a few materials don't play well with it. Avoid soft metals (zinc, copper, brass), raw (unpainted) aluminium, and aftermarket window tints. These can discolour, etch, or peel on contact with alkaline cleaners. Unknown or unusual surfaces — always spot test first.

⚠ Not suitable for

Soft metals (zinc, copper, brass) can discolour or tarnish. Raw aluminium can oxidise or pit. Aftermarket window tints can peel or cloud. These materials react with alkaline cleaners, not just Universal Cleaner.

No soft metals No raw aluminium No aftermarket tints

How do I spot test Universal Cleaner on a surface?

Pick an inconspicuous corner or hidden area (the back of a cabinet, underside of a chair, hem of upholstery). Apply a small amount of diluted Universal Cleaner to a microfibre cloth, wipe gently, and wait a few minutes. Check for discolouration, etching, or surface change before cleaning the full area.
