Exhaust System Deposits Contamination

Exhaust-residue contamination, it arises from carbonaceous and metallic deposits in engine emissions, which accumulate tenaciously on surfaces exposed to high-heat flows. This layer, it distinguishes itself by its oily, layered adhesion, unlike dry rust that flakes easily, and behaves differently on metals: on steel and stainless steel, it penetrates deeply, while on titanium, it manifests as a superficial film resistant to abrasion. Removal challenges stem from its chemical bonding, yet laser cleaning proves effective, as the process vaporizes residues selectively without substrate damage.
