Description
A strong mixture of fast-acting chemical structures based on modified orthophosphoric acid that dissolves metal oxides. In combination with particles using surface tension, it allows penetration deep into corroded surfaces. It is also used to remove dirt from cement mortars, rust stains, etc. The gel structure allows the preparation to be used on vertical surfaces.

Directions for use
The surface should be cleaned of loose rust and dirt. Apply the preparation with a brush or roller, leave until the rust dissolves, then wash thoroughly with water and dry. For slightly rusty surfaces, the preparation should be left on the surface for a period of 5-15 minutes, if there are already pits on the surface – rust removal time may be several hours. If, after rinsing with water, the surface needs to be reused, it can be applied without drying.
The product acts aggressively on some galvanic surfaces (strongly galvanized). When cleaning such items, act briefly and locally.
Tests on a small surface should be made before each application.
