Oxalic Acid

[bike]

I have used muriatic

muiradic acid was my thoughts at home depot it is a great rust remover also.

and then stored the tightly closed container in a metal cabinet- fumes caused rust! I now have the container in a sealed plastic bag...

I added another 2.5 cups (40 tablespoons) to the 80 gallons of water . I believe the mixture is now 1 tablespoon per gallon of water.

The blue tarp soon sprung multiple small leaks (about 10 gallons a day) so I moved the operation to the driveway. Last night the temps were cold enough that the fish tank heater could no longer keep the mixture from freezing. The frame , rear wheel and drop stand had been soaking for nearly a week.

I removed the parts from the solution put them in the bath tub to soak in water and wiped down with a cloth to remove the surface scale (BTW; I wouldn't use the bath tub again, even for rinsing, it makes a huge mess). I removed the parts from the water and sprayed them down with the apply when wet spray wax to keep the parts from flash rusting. The original paint is missing in a lot of places and is very tired where it still is but my intention is to have the motorbike look as it had been pulled out of a barn so I will keep it this way.

Looks good. You may have to clean it up a few times and/or rinse a few more to be sure all the OA is gone and that the yellow stuff gets removed too.

Fish heater? I hope your fish don't mind donating that to the cause!

The stuff won't go bad in storage, but the water will disapate if left in the open increasing the acid strength. its good junk to use but it is a acid and will eat away skin and other things it will harm paint an cause it too lift off the part.

I use white crystals and start at about 2 tablespoons per gallon of water. You can use much stronger or weaker; the concentration seems only to affect the speed at which it works. You can collect in a container and re-use, adding more powder if it seems too slow.

I find it works best on chrome plating that is still mostly sound under the rust. I find it counterproductve if the plating is too far gone. It turns some types of plating green, grey or black. It quickly removes some type of plating used on spoke nipples.

I know this is a old thread but you say you use white crystals.Are you talking about oxalic acid.If so can you tell me were to buy this in a crystal form,all i have seem is a liquid

Try a paint shop like Duron, Benjamin Moore, or Sherwin Williams. Some of the small, old style hardware stores also have it. Look for Savogran Deck/Wood Bleach in the small plastic cup-type container. If you read the smaller print it should say oxalic acid somewhere.

Try ebay.. The wood bleach sold at hardware stores cost around $7 or $8 for a 12 oz container. You can pick up 2lbs on ebay for $11.50 shipped.
