TL;DR: Universal Cleaner is safe for most household surfaces. Avoid raw soft metals and use caution on aftermarket window tint films. When in doubt, spot test first.

Surfaces to avoid

Raw soft metals

These metals can be reactive and may discolour or mark when cleaned with alkaline-based products. Universal Cleaner has a pH of 12.5, which is powerful enough to cut through grease but reactive with soft metals.

Raw aluminium Copper Brass Zinc

Glass coatings and films

Aftermarket glass coatings and films can have compatibility issues with cleaning solutions. Always follow the manufacturer's guidelines for cleaning coated glass.

When in doubt, spot test

There are many different finishes and manufacturing coatings used in homewares and building materials, so it is not possible to list every surface. If you have any doubt, do a spot test in an inconspicuous area before full application.
