It is an almost odorless, solution that has the ability to rapidly corrode bronze (and copper) and turn it into a green patina on the surface that does not allow black, brown or other shades to form. It is worked by immersion in a plastic container. Depending on the dilution with water, it gives the corresponding colouring. Orbipat is worked in a bath. Objects must be cleaned from oil and dirt with Orbipal. Dwell time in Orbipat 10-30 minutes.
