Renaissance Metal De-Corroder is a museum-grade metal preservation tool you can use to remove rust spotting, pitting, and staining without modifying the underlying steel appearance at all!
Treatment selectively ruptures the bond between base metal and corrosion layer, reducing rust to a sludge which is easily wiped or brushed away. Clean-water rinse stops the process.
Even relatively prolonged immersion over several days has no significant effect on sound metal, thus giving the conservator complete control over the process – and freedom from it.
The totally benign nature of the product eliminates work and health hazards associated with common de-rusting systems such as those based on phosphoric and hydrochloric acids. Gloves, masks or protective clothing are not required; normal ventilation and common-sense hygiene procedures should be observed.
Following treatment, metal surfaces are stabilised for up to 14 days, giving ample time for applying long-term protection (such as Renaissance micro-crystalline wax polish, which confers a tough – but reversible – glass-clear lustrous finish).
