Yes, Boeshield Rust Remover is effective but it’s also very noxious. I bought it in a small pump spray bottle to clean the rust off of woodworking machinery. It filled the air with its vapors. Definitely an outdoors in a breeze product. It’s about the same as the Kleen Strip product, though. Any phosphoric acid solution strong enough to remove rust is going to be harsh.8 MONTHS?
Wow, you got me beat. I left a part in the Boshield rust remover for a week and it corroded the hell out of it. Do not confuse this with their T-9 offering, T-9 is great.
The rust remover is so friggin harsh and poisonous I may just toss it.
A soak in Evaporust cleaned that hot mess up fine though.
