Acid-free descaler (formerly Azule Cement Stain Remover)
Acid-Free Descaler is a cleaner specially developed for removing limescale and grout residues on lime-bound tiles such as cement tiles. This descaler is a lime binder and does not affect the surface of sensitive tiles. Its lime-binding properties collect excess deposits on tiles after which it can be easily rinsed off.
Good to know
Acid-free Descaler is used after grouting to safely remove excess grout and glue residue from cement tiles. We recommend using our Acid-Free Descaler also just after grouting but before grouting to remove any glue residue and limescale so that it does not have a chance to soak into the tiles. It is also suitable to use diluted as a replacement for an acidic product such as Antikal, and use it to clean the shower area (floor, wall, taps and glass) of limescale without affecting the tiles.
How to use Acid-Free Descaler
Dilute Acid-Free Descaler with water according to the indicated dosage and apply to the surface with a sponge. Leave for a few minutes and then scrub the tiles thoroughly. You can repeat this process if necessary. Then let the tiles dry for 12 hours.
Depending on the contamination, dilute the Acid Free Descaler with clean tap water in a ratio of 1:10 to 1:2.
Suitable for all types of tiles but specially developed for porous and sensitive tiles such as Portuguese Cement tiles and natural stone.
