Rust eater strength

yes, if you like to pay more. Not otherwise afaik.

and your first question... youtube shows an assortment of rust eating chems, many of which are far cheaper than phosphoric acid.

slivki show did a vid comparing several. soda didnt work ketchup worked, all off coke: just a little removed toilet cleaner: just a little removed lemon juice: 75% removed vinegar: 100% removed. best, quickest, cheap

Someone else claims to have removed rust with potatoes!

I've used acid-based rust remover (phosphoric and hydrochloric) with variable results in various applications. Then after seeing many recommendations online I bought some EvapoRust; bloody marvellous stuff

- no risk of dissolving what you're trying to clean, no worry about splashing acid where you don't want it, no attached residue of converted rust, just a black powdery precipitate that rinses away to reveal shiny steel. For a BBQ I'd probably just attack it with a wire brush on a grinder, then apply a coat of oil every so often to keep the rust away.

Thanks very much both. I used vinegar on some screwdriver bits I left out in the rain. A good soak for a few days and it did the trick. With. BBQ soaking will be a bit more tricky but. Look at the YouTube video and also the magic stuff you recommend.

Thanks

Lee.

I use the stronger 85% strength.
