This construction gives it strong general resistance to moisture, detergents and many common cleaning solutions used in professional settings. However, "stainless steel" covers several grades with differing chemical resistance, and certain harsh chemicals—strong acids (e.g., hydrochloric, sulfuric), strong alkalis, concentrated bleach or chlorinated solvents—can attack or pit stainless steel over time, especially at elevated concentrations and temperatures. Prolonged contact with highly corrosive agents or frequent exposure without proper rinsing may reduce lifespan or lead to corrosion. Conclusion: For typical professional cleaning detergents, soaps and foam agents the Foam Lance with GW BSP / DN11.8 Plug, Stainless Steel should resist corrosion and perform well. For highly aggressive chemicals (strong acids, strong alkalis, concentrated chlorine-based products), avoid prolonged exposure or consult the chemical manufacturer and verify the specific stainless steel grade before use.
