Where do you get Oxalic acid? I tried the local Ace Hardware. The didn't have any and had never heard of it. I read that it is sold as wood bleach. Any brands I should look for it under? Is this sold at a Home Depot?

Thanks,

Doug

Got mine at Lowe's I think. You will find it in the paint section labeled as "Wood Bleach". Check the ingredients and you will find Oxalic Acid.

there have been threads where people mentioned the name brand at Lowes but I don't remember it
I got mine here

if you should read the research in regards to oxalic acid they specifically describe a purity level of 96%. I realy doubt that 'wood bleach' will be quite that pure???? And what about the impurities in wood bleach.... do you think the label will identify all harmful ingredients for a product that is designed to wash the color out of a wood fence or deck? so once again cavaet emptor...

my question; is oxalic considered to be organic or inorganic?

that's why I got it from a chemical supply warehouse
it's an "organic acid" so I would say it's the 'O' word, although to be honest, I don't know what that word means in a technical sense

hmm, dictionary.com says it means it's carbon based
that clears that up doesn't it smile.gif

Dave

[edit]I would also point out there are two different compounds running around
oxalic acid dihydrate and oxalic acid anhydride
the first has 2 water molocules stuck to it
so the second ends up being 25% stronger
the one from the chemical supply place is the second
the wood bleach guys don't mention which they use
might make a difference on effectiveness

With utmost respect, where have you seen research that describes 96% purity?

Got a link? smile.gif

Mine came from Ace. I would try any paint store, like Sherwin Williams, etc. If you're really worried about impurities, what's in that 4%? I'm pretty sure mine is DAP brand and is described as technical grade.

"Organic" chemistry is basically carbon based so any chemical with carbon present is basically an organic compound oxalic acid formula is H2C2O4 as opposed to inorganic like hydrochloric acid HCl where the Cl is chlorine. **** a BS in chemistry can come in handy. :D

Jeff,

you're in trouble now
you've outed yourself
now we know who to come to for chemistry info smile.gif
am I correct in assuming that when you vaporize the dihydrate form of OA the water is driven off as steam??

inquiring minds want to know

The wood bleach works fine.

I've been to Ace Hardware, Home Depot and Lowes. Each time I get the blank look whe I ask for either wood bleach or oxalic acid. I really needed some. I'll just do the mail order thing and wait until it gets here.

I originally bought mine at Lowes. I was there the other day looking for some and the one by me doesn't carry it anymore.

Dan,

that's what happened to me
went to home depot with the name brand Sanogran
the guy had heard of it and thought he knew where it was on the shelf, but we couldn't find any
he guessed the stopped selling it

Wish I would have checked ebay first! I paid $4.20 at www.ChemistryStore.com (http://www.ChemistryStore.com) but had to buy something else because the minimun order is $10, the ne the nailed me for $12 more for shipping and $3 for a "handling fee". I hate handling fees. They should just charge me for what it costs. If they don't make enough $ on the product, they need to raise the price. Now I'm into it for $25 for something that's supposed to cost less than $5!

GO TO LOWES, look in paint dept for a pint container that says, "Savogran (mfg name) Oxalic Acid Wood Bleach" (white container w/ red lid).

Read the container:
Bleaches uncoated wood
Removes black water spots and stains
Gently lightens wood

I just rechecked my local Ace Hardware. They stock Savogran. I also remember seeing wood bleach at Wal-Mart and Lowe's. Don't ask the workers. Few would know every product on the shelves. Just go to the shelf where the wood stains and wood finishing products are stocked. It is there.

Doug,
Go to Hi Valley Chemical in Centerville. Their address is:
1134 W. 850 N.
(801) 295-9591

Mix 1 oz. with 8 oz. warm water and 8 oz. syrup (6 parts sugar to 4 parts water)...
This solution has 1.77 grams Oxalic acid per oz.
Spray between frames (use about 2 oz. per hive)

They sell by the pound so it would be a good idea to find some beekeeping buddies (better yet your local club) and split it with them. It is about $8. They sell 10 lbs. for $46.53

Wow! Thanks to all who responded to this post! I am humbled at the time and effort you all have put into this. I will let you know the results when I have some.

kc in wv: great posts. I will remove the honey supers, but according to your posts, it doesn't look like it's necessary.

Vickie: Thanks for the local info!

Thank you all!

Doug

If your local ACE doesn't have it, they can order it. The SKU is 11221. Unfortunately, it can only be ordered in units of twelve, so they might want you to pay for all of them.
