BOESHIELD T-9 Rust Protection and BOESHIELD RustFree Rust Remover

No idea how the rust/stain remover works. It has to be literal magic, recently got into hobby machining which means old rusty stuff. A few sprays of this and a scotchbrite pad makes metal look almost new. Obviously it doesn't take out gouges, but it makes any steel I've sprayed it on shine again.It does leave a white waxy surface if you just let it dry, and if it remains wet it can stain black but just hit it again and your good!The rust preventative seems to work well to! Haven't had any surface rust pop up on treated surfaces (yet) .

I use these on all the cast iron surfaces in my basement workshop. The acid is harsh without a mask but it works great. The T-9 has kept everything rust free despite the humid environment. Unlike waxing theres no residue and pieces stay clean. It does take a while to dry on the surface but well worth the time investment.

Purchased this for table saw top and other metal machine surfaces after reading many reviews on reccommended products used to preserve and prevemt rust on cast iron machine surfaces. I am well pleased after purchase and use. Use a THIN film let dry, and wax over with automotive paste wax. Works like a dream. High humidity climate is no match for this product. No surface rust weeks after thin coat only applied. Also great on bicycle chains, hand planer surface, garden shears, and any tools that typically rust. My only complaint is that I didnt purchase 2 cans!.
