Cecil Posted February 3, 2008 Report Posted February 3, 2008 I just ordered some from the local drug store. They did not know what it was, but they checked and they could order the crystals. Quote Cecil Wakelin http://home.bellsouth.net/p/s/community.dl...d=359493&ck=
Members bcurrier Posted February 3, 2008 Members Report Posted February 3, 2008 Barkeeper's Friend (stainless steel cleaner) is basically Oxalic acid. Never occurred to me to use it for leather, though. Bill Quote
Members DelNeroDesigns Posted February 8, 2008 Members Report Posted February 8, 2008 I don't think I can help you with that, I think you're supposed to dissolve a teaspoon in a pint of warm water, but don't quote me on that. However, I would love to know where you got it from. As a matter of fact, does anyone know where I would be able to acquire crystallized oxalic acid?Marlon I bought it to bleach wood when trying to color match a piece. Check with a woodworkers supply. Are you using it to bleach leather? Quote
BevJones Posted February 8, 2008 Report Posted February 8, 2008 Caledon Leather Sales has it too. They are on this site under the Suppliers. Click on the link and then select Supplies, scroll towards the bottom and you will find it. Quote
Contributing Member TwinOaks Posted February 8, 2008 Author Contributing Member Report Posted February 8, 2008 Well, I thought it could be used to bleach leather. I've done some pieces that required WHITE and I don't really want to get into partially painted pieces- keeping mostly with the natural look ya' see. So, I thought it might bleach the leather whiter than just the tanned color. I also tried it to try and pull a drop of brown spirit dye out of a piece. oops. Sometimes the obvious needs to be clearly printed on the label: If you are new to coloring leather, do not dribble this stuff where you don't want it 'cause it will NEVER come out. like I said...oops.

stelmackr Posted February 10, 2008 Report Posted February 10, 2008 Will someone please provide the uses and directions for using crystallized oxalic acid? Dissolved in water and used to clean (or bleach) leather, wood. It is poison and can be absorbed through the skin and damages the liver. If used before applying Tandy's Antique dye, it turns the color purpleish.

It is poison and can be absorbed through the skin and damages the liver. If used before applying Tandy's Antique dye, it turns the color purpleish. Bob A couple more questions: 1) Someone recommends neutralizing the leather afteer you clean it with an oxalic acid wash. How do you do that? 2) How do you apply the oxalic acid wash to the leather? Can you use a sponge or paper towel? 3) Is the wash (1 tsp/pint or whatever the mixture posted above was) safe to handle with bare hands or should you use gloves? Quote

Now this is a scary thought. Maybe my teacher was a little off, but he taught me to use Bleach to bleach leather. No acid, no crystals. 2 tablespoons Bleach, mixed with water. I use a 16 ounce pickle jar to store it. (cleaned out of course) I have NEVER used the acid stuff. He taught me bleach does exactly what the acid does, and a gallon of bleach goes a whole lot farther. Quote
