CARCOS 2601 is a product with an innovative formulation designed to facilitate the removal of carbon residues. Its special formulation has been developed to dissolve the dirt generated by combustion fumes on mechanical parts subjected to high temperatures. CARCOS 2601 has to be sprayed abundantly on the surface to be treated at a distance of 15-20 cm. In the case of particularly hardened incrustations we suggest a contact time up to 10-15 minutes to favor the chemical dissolution. Repeat the operation after a few minutes in the most difficult cases.
