Ive had a bucket with 6 litres of vinegar in the garage for the last week with numerous bolts and brackets in. It does the job but fookin stinks the garage out LOL!

The kids keep asking what the smell is...

It does work though. Sometimes it pays to get the bits out after a couple of days, lightly go at them with a wire brush then pop em back in to soak.


I might try the coke next. (at least it'll smell better!!!)
