Review: I wish i can post photos to show how effective this gel is… tested it once i received on a very rusty stainless steel lock , sprayed the gel and waited for around 30-45 mins then scrubbed it with steel brush , from the rust started to dissolve like magic. This product is very effective and i am truly happy for finding the solution that can restore whatever is rusty and old back to very good new condition. Strongly recommend if you have rusty metal.
