seeing is believing

What you see is a pair of very rusty 1948 huffman fenders......before and after being submerged in Savogran Oxalic Acid [wood bleach] for 14 hours. notice the one rear fender I only put partly into the solution . you can clearly see the untreated rusty part. these fenders had very deep rust. I purposely put the front fender in the solution with the Winner light left on the fender to see if the Oxalic acid would eat up the aluminum light bulb shield . As you can see there was no affect on it. Acid Magic acid would have dissolved that in about 30 seconds.
I did not clean the fenders after the treatment. took them out, wiped off and took the photo.
with a little wax and some polishing these fenders would look good I think.
I used 4 heaping table spoons full of oxalic acid powder to 8 gallons of hot water. Just guessed on the amount.
I am sold!!!

OA is a godsend. Be sure to dry them and coat them in oil soon after removing from the solution. I think this is actually the original purpose of Water Displacement-40 and it works great. They will rust back up pretty quickly otherwise.

Kool,where do you get OA??

I typically get mine at the old school hardware stores. Works too well for Home Depot or Lowes to carry it. It's a powder in a little tub that is, more often than not, labeled "wood bleach". That or you can get it on ebay by the pound. Lasts forever too since a few good spoonfuls can be used for a kiddie pool of hot water.

Hey Vince! The sun shinning hereand all is well. hope your day is going as good as mine!
Bought the stuff at Ace Hardware. Not every Ace stocks it. 10 bucks for 12 Oz. tub.
you can get it online in bulk cheap, but one 12 Oz. tub should do two or three complete bikes easily. No smell,fumes, and and what the heck I might soak my feet in it, the way it cleaned up those fenders it should do wonders for toe fungus....

most wood working places carry it, not at HD or Lowes or even ACE. There are some cleaners with OA in it but the strength is not the same.

Or order it, http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias=aps&field-keywords=oxalic+acid+wood+bleach

I caught flak for posting this before, but what the hell, I guess I'm a glutton for punishment.

As suggested by another member on this site, and I don't know if it's overkill or not, but after a OA bath, neutralize the object in a solution of baking soda and water, just to be on the safe side.
