Solvent cleaning NO!NO!
I recommend you not clean your machine stuff with parts cleaning solvent
(degreaser). Last week I went to pick up a 8" Spacer that I had won on eBay. The seller had a whole area of his large production shop set aside and staged with extra and machine shop equipment and accessories. Every item was clean and bright. In addition to the Phase II Spacer, I purchased a 4" Dividing Head w/4 plates and a 10" four jaw D1-4 chuck. After a long drive home, I unloaded them in my unheated work shop. I live in the Pac. NW and cold metal gets damp and flash rusts if it isn't lightly oiled. You guessed it. These new treasures were so clean that they flash rust over night. I was sick since the bright finish of yesterday was now a cool copper color on all surfaces. I tired wiping it with a lightly oiled rag but all I got was rust stains on the rag the smeared onto any surface that hadn't flashed yet. I've got it under control but I'm not sure what procedure I should follow to get it back to bright and unstained again. The best I can figure, is they ran these items through a solvent degreaser since the internal parts don't seem to have any lubricant remaining. Just my opinion and experience, FWIW. Steve |

Soak/spray them w/ any nondetergent oil for protection, esp. the innards.
PB Blaster and Kroil will remove the "flash rust", to a large degree, and protect the metal--seems to soak in. WD40, in light of my recent exp. w/ Blaster/Kroil, is a few cuts above water. You can find aerosol PB Blaster at some autoparts strores, but the gallon cans of Blaster or Kroil must be bought direct. Costco atomizers work well for spritzing metal around the shop. I spray Blaster on lathe ways, after they're wiped by the carriage or tailstock. Someone made a blend of oil using Marvel Mystery Oil for this, as well. I'm thinking of mixing something w/ Blaster for a little more viscosity. Yeah, greasy, crappy shops are rust-free shops! -- Mr. P.V.'d formerly Droll Troll "Steve" wrote in message ...

WD-40 To finish racing John's terse posting, AVOID WD-40 AT ALL COSTS. It isn't an anti-rust oil. It isn't a lubricant. It isn't a penetrating oil.

Good lubricants are usually specified in machine manuals, but nondetergent 10 wt motor oil is pretty good to start with. Good penetrating oils include Kroil, Aero-Kroil, PB Blaster and others. GWE |

Hmmm, I agree and don't.
Yes, WD-40 is a crappy oil, but it cleans way better than kero! Dave |

However, a cupla people asserted that wd40 is the best tapping fluid for aluminum they've ever used! WD40 bought out 3-in-1, and I think a cupla others--cornered the effing market w/ their own crappy product. I wonder how they did that? Sorta the Microsoft of spray oil.... Yet, they explicitly *claim* all that you correctly observe wd40 is not. In a thread some time ago, someone asserted that wd40 never claimed to be a lubricant, but indeed they do! You can't appreciate how useless wd40 really is until you've tried the other stuff. Another product I like (found it at home depot) is Corrosion Pro by lubrimatic, a "spray grease" that seems to be sorta between an oil and chain lube for motorcycles. Speaking of which, chain lube for cycles is great stuff also, if you want stuff to really hang on. Some have moly, lithium, etc. Sorta like a lower-viscosity cosmoline g, might be great for the OP. Kroil or PB also makes sumpn w/ graphite in it, as well. -- Mr. P.V.'d formerly Droll Troll Good antirust oils are what they sell in gun shops, or just use way oil.

Rust Lick makes some nice products for this too.

Kerosene is perhaps the most common cutting fluid for aluminum, and WD-40 being largely kerosene, it ought to work. I buy my kerosene a gallon at a time, costs a couple of bucks. Those spray cans of WD-40 cost what? Who cares? Why pay it? GWE |

Those posters seemed to indicate that wd40 was better than plain kerosene.
But it would be interesting to do an A/B comparison, to see if there really is a diff. .. fyi, a gallon of wd40 from HD is about $10-11. Mebbe sprinkle a little perfume in yer $2 gal of kerosene, a little graphite, and voila, DIY wd40!! Yeah, calc out the cost/gal of wd40 in those li'l midget purse-sized spays. Really cute, really good marketing, proly calcs out to $150/gal! -- Mr. P.V.'d formerly Droll Troll "Grant Erwin" wrote in message ...

Wipe some WD-40 on the anvil of your micrometer and see how well it cleans.
Then figure out some way to remove the film it leaves, which BTW, you can measure since your mic won't completely close anymore. Bob Swinney wrote in message ups.com... Hmmm, I agree and don't. Yes, WD-40 is a crappy oil, but it cleans way better than kero! Dave |
