Oxalic acid
« on: December 22, 2017, 04:01 PM »
Going to make a start on my Peugeot build over the festive period and have bought 500g of oxalic acid so I can give the frame a bath. Does anyone know the ratio I need to be mixing this stuff? Frames not too bad just a bit of light pitting and surface rust here and there.

I don't really use a ratio. Fill the old wheelie bin up with water and mix a 1kg tub of crystals in. Normally 24-48hrs is good enough. If you have a chance rub the yellowing off the frame a few times over the time period.
