OK Boys and Girls I recently had a project where I needed to clean my driveway concrete and reading the product label it stated that it does metal as well and as I own jaguars I am used to rust !!!
attached in order are pictures that were taken approximately 2 to 3 minutes apart and do not after the third picture I gave the metal a second coat and the final picture I wiped with a rag.
This was surface rust I do not know how it would work on heavy rust.
The product was cheap and I bought it from Home Depot.
Hope this is of interest and please share on other forums.
