Evaporust and Rust 911 are not acids and won’t harm copper brass solder etc. Infact Rusty 911 is Biodegradable and way more environmentally friendly than any highly toxic product like carb cleaner, lacquer thinner or similar product and will not get ever close to cleaning gas tanks as Rust 911. I personally have tried them all to include Muratic acid. Denatured alcohol would be my second choice.
