Oxalic Bath Question?

<< < (2/5) > >>

BMX1973:
I normally leave it in overnight for about 12 hours or so.  :)

hokuspokus74:
Have the stuff in soaking now,whatabout the yellow stuff that starts to form on the parts,and how much of it did you put in?

BMX1973:
Dont worry about the yellow stuff. Its just the oxy attacking the rust. Normally come in 1kg tubs. I put in about 3/4 or about 750g so have a bit for spare. If I get a chance I normally mix the water round every few hours.  :daumenhoch:

yeah it was a 5kg one i got of ebay £27 approx,its been in about 14 hours so do i keep adding more acid to it etc i read a thread on bmxmuseum and the guy said to keep removing that yellow stuff or it will stick and wont be able to remove it,so what do i do ?

might have a bath in it  "wantit" :p

I've never had it stick just washed it off with water. If your concerned take it out and wash it off then put back in. Be careful adding more and more as it will get stronger and stronger. I personally think it could have an oposite effect. Thats why I go for a weaker mix and leave for the 12 hours, never left it longer than 18 hours. Keep stirring. Just keep an eye on it if it is strong and left for a long time. Should deffo not need longer than 12 hours if its a strong mix. Once its dry peek polish it. Try not to leave this longer than 24 hours after removing from the bath.
It can sting that stuff when you get it on your skin.  :daumenhoch:
