You could treat the saws with WD-40 initally to remove dirt/rust and clean them off with other solvents prior to storrage.

>I've used WD-40 as a lubricant when cleaning up saw blades with abrasive paper - never had a problem. I use mineral oil cut with baby oil as a rust preventative after cleanup - this works pretty well. Seems I read in one of the recent woodworking magazines (Popular Woodworking?) that WD-40 actually compared well as a rust preventative, despite all of the bad press to the contrary.

>I read it somewhere that WD 40 was designed to be a water dispersement. I dropped my water hose while washing our car and naturally it landed on the handle and with the garage door open it doused my table saw and jointer.

Liberally sprayed WD 40 on both items and it got under the water and no rust problems. The WD 40 actually pushed the water off the tools as I sprayed them. I wiped them off with paper towels to remove the excess WD 40.

>On all the saws I have cleaned up(I guess about 25 now) I have used WD40 to lubricate the 320 grit sandpaper. Lots of WD40. When I'm done with the sandpaper, I go over with a rag, and then they get a final coat of paste wax. The saws have seemed to held up pretty well in my less then dry basement.

>Roy,

Perhaps I'm thick. Nope. There's no "perhaps" about it. But I seem to remember...ahh...yes...it rises from the mists of time ago...

The focus softens...there's a gentle crescendo of sleepy music...the light slowly dims...

Wasn't it argued nearly to death a while ago that WD40 ought not to be used too liberally because of the danger of WD40's silicon interacting with various finishes? I'm not certain what conclusion was most persuasive, but my rapidly fading memory is that one shouldn't use WD40 for that reason.

Anyone else? Anyone with a better rememberer? or a worse forgetter?

>Alan,

I checked this out on the WD 40 web site. They clame absolutely no silicone. They claim it is harmless to wood, paint and finishes. I remember the discussion that you are talking about, though.

>Roy,

Thanks. I'm glad someone remembered. (Actually, I'm glad I wasn't hallucinating--again.)

I still wonder though. Do the WD40 folks say only that it contains no silicon? Or do they say it will not interfere with wood finishes?

Enquiring minds want to know.

anybody doing some test finishing today?

>I suggest somewone on this board who has the finish rag already in their hand do a couple of test pieces. Take a piece of scrap hit it a couple of licks with a plane on one side, stop and spray down the plane sole with a reasonable amount of WD40 wipe it away like you would any other cleaner then give the other side of scrap a couple of licks with the same plane. now apply whatever finish you are working with and report back to the board. Sounds easy (especially since I don't have to do it). ;>)
