Title: Oxalic Bath
Post by: Swivel on September 26, 2007, 02:11 PM
Been reading about this and a bit concerned i'd mess things up, so need advice. Just bought a mongoose survivor and parts could do with being cleaned up or rust removed. I understand from what I've read that a Oxalic bath will sort out the parts and bring them back to a very good condition.

Where do you buy this stuff and has anyone does this before?

Any advice given would be useful.

Thanks in advance,

Riz ;)

My local powder coaters do the acid bath & shot blasting for free.

they only Charge £20 for f&f too.

It might be more sensible to get out the yellow pages ;)

I didnt mean it would be better than dan, but a lot easier to find somewhere local usually than spending it all on couriers.

im sure theres a lot of workshops, maybe classic motorbike restorers? that would be up to the job.

Its nice to find good trades people locally.

Easy peesey!

Buy a builders plastering bath - about £20.

There is a link on here somewhere where you can buy Oxalic acid in crystal form. It comes in a tub of about 1kg if i remember. Fill the bath with water and then put the crystyals in. Give it a stir and then sink the f+f. Leave for 2 days and presto.

Give it a clean with hot sopay water and then a light polish with Autosolvo and it comes out like new.

No good for bad pitting though.

make sure you protect the frame after Oxalic acid treat meant tho - it needs to be protected inside and out or it will accelerate the rusting process  :daumenhoch:

you know what i was going to post something regards the future rusting on the frame due to being submerged in water and acid?  surely a steel frame (let alone a 20 year old one) shouldn't really be submerged in water as you're never going to dry out the inside properly? therefore rust from the inside out!  :-\

tbh  it would takes years and i mean tens of years for the frame to rust from the inside out

basicaly  when you submerge the frame in stripper or acid a powder coater would dry the frame of

before coating then it's dried again after painting, so the rust on the outside is now sealed and the

inside has just been cleaned,  also bikes are left mainly indoors so are in a dry enviroment

only leaving it out doors for years on end would it rust ;)
