The company I work for sells a lot of medicine cabinet stuff including Purell hand sanitizer in small squeeze bottles or in a flask with pump. And with the flu pandemic going around everyone in the office was given a couple bottles of the stuff.
Yesterday I needed to use my Browne and Sharp dial caliper and discovered it on the bottom of a heap of swarf. I have no idea how that caliper got on the bottom of that pile of swarf, Officer Oppie...
Anyway, something got picked up in the rack and gear so that at every inch of travel it went clunk. So I pulled the rack off, careful not to lose the four motes they call screws, and noted that the rack, while pretty cruded up, did not have any swarf wedged in it. That left the gear which is pretty much impossible to get to.
Now right there on the kitchen table when I was disassembling and analyzing things and stacking threaded motes was a small container of Purell. I pulled the cap off and dunked the rack into it and then slid it into the caliper then gently swashed it about some. Then I pushed it further in and wiped it down with a paper napkin, then removed it.
Now the deal with Purell is it is mostly water and alcohol with a little bit of oil so your skin doesn't dry out. But it's thick so clings and transports like grease but then goes away, finally.
I cleaned it up and tried the rack again and it's better but not perfect. Dunk, swash, wipe, repeat as necessary. Voila, as the French say, it's cleared and smooth again. Next I got out the utility tooth brush, dunked the rack again, and used the toothbrush to clean out the leettle bitty teeth on that rack. It worked a treat.
Before I put it away I dropped a spluge on a piece of 12L14 which I consider to be the least happy metal to be found the the Pacific North Wet and this morning I checked it for rust - nothing there. Not to say that Purell can't affect things, but so far, so good.
I put a flask with pump on my chem shelf.
