Restore rusty steel and iron components and tools. Non-acidic, water-based formula only removes the rust and is harmless to plastics, rubbers, and non-ferrous metals. It protects against further corrosion. Dilute up to 20:1 using a polythene or stainless steel container as a de-rusting bath. Degrease the item first, using Restore pre-clean degreaser (available separately), remove loose rust then suspend it in the bath. Once clear of rust rinse clean and dry.
