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 5-15 minutes, if there are already pits on the surface – rust removal may take several hours. If, after rinsing with water, the surface needs to be reapplied, it can be applied without drying it.


The product has an aggressive effect on some galvanic surfaces (strongly on galvanized surfaces). In the case of cleaning such items, it is necessary to act briefly and locally.

Before using the preparation, tests should be carried out on a small area each time.
