Oxalic Bath Question?

<< < (3/5) > >>

hokuspokus74:
I took the frame and forks out of the bath still has a good bit of rust on it,i had it in soaking for just over 36 hours,so i think its of to  the powder coaters for these,it did a good job on a set of gt forks though.

Any ideads of why it didnt remove all the rust with it been in so long etc.

No idea why it didn't remove all the rust, it should do. Do you mean there are black marks where the rust was? If so the chrome has worn and so too has the yellow nichol underneath back to the metal of the frame.  :-\ If it still looks good then build as a rider everyone likes a survivor bike. If for show maybe get a paint job in an original factory colour. Get some pics up of it.  :daumenhoch:

Yeah - lets see pics.

Next time use Citric Acid - OA can cause a 'bruise' stain on the chrome on thinner chrome jobs.

Bath tub half full of water, half to three quarters of a kilo of Citric and 24 hours does the job normally - sometimes quicker. You have to occasionally with an old toothbrush go over the rusty bits.
