Allow it to dwell for a short period, as specified by the manufacturer, usually a few seconds to a minute. Do not let it dry on the surface. Agitation with a brush may be necessary for heavy contamination. Immediately and thoroughly rinse the surface with plenty of water after the dwell time to neutralize the acid and remove dissolved grime.
Can acid cleaners remove deep scratches or pitting?
No, acid aluminum cleaners are designed to remove oxidation, stains, and surface grime, not to repair physical damage. They work by chemically dissolving contaminants and a thin layer of oxidized aluminum. Deep scratches or pitting are physical imperfections that require mechanical processes like sanding and polishing to address.
What should I do after cleaning aluminum with an acid cleaner?
After thoroughly rinsing and drying the aluminum, it is often beneficial to apply a protective coating or polish. This can help prevent future oxidation and staining, keeping the aluminum brighter for longer. For raw aluminum, a dedicated aluminum sealant or wax is a good option to maintain the restored finish.
