The Joy of an Acid Bath :)

So how much did you spend on the Oxalic Acid ? What do you do with the 'waste' product ?

A new chrome seat clamp-set is only about £3 off fleabay,
but then you can use the acid on other parts like rusty skewers/washers etc etc.

Thought I'd post this for anyone planning their first restoration/rebuild project.

Top tip, thanks. As it happens I have just stripped down a bike for cleaning. Can it be used on unchromed parts that just need a bit of cheering up?

Couple of non-bike related points:

Sorry to come across as some sort of "crime pedant" but Rillington Place was Reg Christie, who gassed his victims.

I work as a school lab technician and oxalic (aka ethanedioic) acid is always labelled as "Toxic"; if ingested it forms insoluble salts (chiefly calcium oxalate) in the body and those salts can accumulate to give you kidney stones. It's the same reason people are always told not to eat rhubarb leaves, which are abnormally high in oxalic acid compared with other fruit & veg. Best to wear rubber gloves when using it and wash your hands afterwards.

I seem to have got my murderers mixed up

Some good advice on the health and safety aspects, I must admit it does smell quite strong when you take the lid off the coffee jar, also it turns an odd green colour after a few hours of soaking parts.

A 500g bag is only around £3 and will last for ages. I use it where its nice to try and keep the original parts, sometimes irreplaceable parts. The seat clamp is "Made in England", well worth saving and not one of your Korean thread stripping bits of crap You can just about make out where its stamped on the back of the clamp in the second pic, can't be seen at all in the first pic.
It can also be used as a drain cleaner so I pour the waste down the toilet.

Thanks for that Rob, I'd never heard of oxalic acid until I read your post and thought the stuff was expensive.
