2) Keep steel blocks coated with a rust preventative oil such as Starrett M-1 when not in use.
It is recommended that if the gages are going to be stored overnight or be taken out of use,
that they be wiped all over with a chamois dampened with a rust preventative oil such as
Starrett M-1. Use the handling procedure as above, and do not touch the blocks during
handling or placing them in their case.
3) Before use, we recommend cleaning the gages with mineral spirits. Mineral spirits leaves a
slight oily film which can offer short term corrosion protection while the blocks are in use.
(The slight oily film left by the mineral spirits will not affect the use of the block.)
Cleaning blocks with alcohol is acceptable, but may leave the blocks so clean they may be
susceptible to corrosion. Also alcohol is a greater fire hazard than mineral spirits.
I wipe my tools with Fluid Film on a leather chamois cloth. It goes a very long way, doesn't discolor metals and is easy enough to wipe off. I keep the cloth in a ziplock bag. Many guys use it for guns, cars and farm implements too. It's lanolin, a natural wax from sheeps wool and its pretty much weatherproof. Never seen any rust on anything I've used it on.
I couldn't easily find a supplier in Canada or a price for the Starrett M-1 "All Purpose Lubricant".
The KBC web site frustrates me, sometimes. I searched before posting but could not find "M-1" or "Starrett M1". Thanks to your pointer, I found it in the paper catlogue and got the part number:KBC sells M-1 in a 12oz aerosol for just over 11 dollars.
Thanks! Never heard of that store before and they don't have much of a web presence. I'm planning to head down that way tomorrow so if time allows I think I'll stop and have a look!E N Tool in Stoney Creek has the Starrett M1 for $9.99 a can (Canadian Funds).
