Hey fellow LJ ers

I read the blogs about rust removal and the use of citric acid or evapo-rust I have not used ether method but I have used a method pointed out in “American woodworker ” issue # 110 page 6 that uses electrolysis with the add of a small battery charger , washing soda and a aquarium . This method works great after you have the basic parts needed (I got mine in a garage sale for around $ 10.00). Other than the washing soda you don’t need to keep buying a product to de-rust with. I”m not picking on the other ways to de-rust just offering another choice. I’m not sure how to post a copy of this article and if I did It might have copy right issues.

Ok. I’ve had to bring back to life a lot of rusted tools. They were piled upon and ignored for 25 years. I tried the electolosis thing and citric. They both work well, electrolisis worked better. Two days ago I picked up 32oz of evaporust for $8+ at Autozone. A rust encrusted.. and I mean encrusted no.4 stanely plane was immersed in it over night. All the rust is gone and I’m thankful and amazed that the metal wasn’t pitted. I just rinsed the blackened film off in the sink afterwards. After leveling, sharpening, and assembling it I spent awhile shaving about an inch off a 24”x3/4 pine board just to see the thin, smooth unbroken shavings peel off. Yes, evaporust isn’t cheap, but it’s not too expensive either and it does exactly what you’d like to have happen. remove ALL the rust and leave the original metal untouched. BTW, you can save it and use it a few times over and over till it stops working. It’s my choice from now on.

David (The Folding Rule Show) has more information on plane restoration using electrolysis here including some diagrams.

Washing soda may be slightly hard to find. A tip to increase chances of finding it would be to check stores that might have a slightly older client demographic – older neighborhoods, etc. I checked three stores of the same company, only to find it in their branch closest to city center. Ask the store manager if you don’t find it at your favorite store, and they can get it for you -as opposed to paying shipping for an internet purchase.

One note I would add to this is that baking soda, which can be found in any grocery story, can be used and, while it can also be used, please avoid salt. The problem with salt is that the electrolysis will give off chlorine gas which is both poisonous and highly corrosive.

Hey Guys
That’s what I like about LJ you can pick a subject an there are so many knowledgeable folks out there that you get a whole different opinions pros and cons in and outs I always learn something. Thanks for your input.

Hey Barn Bob I have been super busy I have Intended to get some shop photos posted I have about ten projects I have to finish first. Your shop looks cool and you have done some neat projects yourself. Your work on boats must have been very interesting,I understand you have to work off reference points because you can’t use levels on boats.

Thanks for your interest

It looks like evapo wins the comparison test I guess I’ll have to try some. and give it a go.
