Concentrated acid-based detergent specifically formulated for the deep cleaning of acid-resistant surfaces and the removal of post-installation residues, stubborn dirt, cement-based adhesives, grout haze, limescale, salts, efflorescence, and other mineral deposits. Its fast-acting, buffered formula effectively cleans natural stone, granite, ceramic and porcelain tiles, concrete pavers, and all acid-resistant materials, restoring the original appearance of the surface. Particularly effective in removing rust stains, mineral build-ups, and atmospheric contaminants. Highly effective in eliminating "engobe" residues and installation-related patinas from acid resistant ceramic and porcelain tile surfaces.

Method of use :
ALWAYS TEST PRODUCT FIRST following the below indications before proceeding with complete product application. Cover and protect all surrounding areas before proceeding with application.
Dilute product as indicated: (recommended dilutions) *
1. For standard post-installation cleaning: dilute 200ml of product in 1lt of water (1:5)
2. For stubborn inorganic dirt and residues, efflorescence and limescale: dilute 100ml of product in 1lt of water (1:10).
3. For surface rust: dilute 100ml of product in 1lt of water (1:10)
4. Light grout haze and residues: 50ml of product in 1lt of water (1:20)
Pre-wet the surface lightly with clean water. Apply solution directly to area to be cleaned and allow a contact time of a few
minutes (3-10 minutes). Proceed to scrub area manually using a manual floor scrubber or mechanically using a mono brush
(175 rpm) fitted with a soft bristled pad or white /red nylon pad. Add water and wet vacuum all residues. Rinse using clean
water and remove. Repeat operation if required. For heavier cement residues or stubborn grout haze, the dilution may be
increased up to 1:3 or 1:1 following a preliminary test.
Coverage:
Granite and natural stone: 25/40 m² * - Terracotta and brick: 10/25 m² - Ceramic and gres: 50/70m ²
(*) depending on the number of coats, texture and porosity of the surface.
Packaging:
Available in the following sizes: 1 lt., 5 lt., 25 lt.
