Shopsmith Forums

It is basically oxalic acid and mild abrasives. My jointer and planer had circular stains in the cast iron tables where someone left soda cans or coffee cups. Nothing touched those dark stains until I used this stuff.

We have used the powered form of this for years but I had not thought of using on my shopsmith nor have I seen it in the liquid form.

I'll pick some up when I go to Lowes again, maybe even today. I'd like to see how it would work on a few things I have with some moderate rust stains. If it works with less elbow grease then present methods I'd like to know about it.

Thanks for sharing.

We don't have any big box type hardware stores around these parts, so I'll have to look for it elsewhere and give it a try.

Ditto on that. I've also used a similar product called Cameo. Both do a great job on stainless Steel and I was planning on trying it on my new to me SS 520. I'll look for the liquid form at Lowes. Thanks RCplaneguy for the posting this.

I found the liquid BKF at Home Depot. Used it this afternoon to clean up my new to me 520. It's doing a really good job.

I used the powder on my shop tools this fall.....I would spread it on the table of the table saw, band saw, all iron tables along with wd40 or white grease to make a slurry, then a fine abrasive pad to work it in and yes it does wonders!!!!

Cool. You might try it with a wet rag rather than the wd40 and grease. Without water the abrasives to do all the work. With water the oxalic acid powder becomes active for rust removal, forming stable ferric salts which easily wipe away. Of course you have to immediately dry and protect with JPW.

Just gotta say I tried it, it's available here at jewel/osco like 2.50 a bottle. Works great, easy no major hard scrubbing.
thanks for the tip.

I got some at Menards yesterday. Was 2.50 a bottle
