Grout & Builders Dust Residue Remover – Acid Cleaner 4

TileMaster Cleaner No.4 is a professional acid cleaner for the post-installation clean. It breaks down grout haze, cement and plaster residues and general builders’ dirt on ceramic, porcelain and acid-resistant natural stone only. It does not tarnish or damage aluminium and steel profiles such as trims, cookers, taps and sinks.

Important — acid-sensitive stone: Cleaner No.4 must not be used on acid-sensitive (calcium-based) stone such as marble, limestone or travertine, or on other polished or acid-sensitive surfaces. If you are unsure whether your stone is acid-resistant, test a small, inconspicuous area first or contact us before use.

How to use

1. For a deep clean, mix Cleaner No.4 at 1 part cleaner to 4 parts water (100ml cleaner to 400ml water). The 250ml Ready to Use bottle is already pre-diluted at this strength (1 part cleaner to 4 parts water), so use it straight from the bottle.
2. Apply to the surface and leave to work for 5 minutes, keeping it wet so it does not dry on the floor.
3. Scrub with the TileMaster machine fitted with the tile and grout brush for best results, or use a stiff scrubbing brush or suitable pad.
4. Remove the dirty solution with a clean mop, sponge or cloth.
5. Rinse well with clean water.
6. For rust marks, apply the concentrate neat (not the pre-diluted 250ml Ready to Use) and leave for 15 minutes, keeping the area wet throughout, then scrub and rinse.

Contains orthophosphoric acid. Wear gloves and avoid contact with eyes and skin. Keep out of reach of children and pets.
