Guys,
i'm not getting in a urinating contest.
Have you ever seen what a loaded abrasive or coarse sisal mop will do to human skin?
If you got a job in a jobbing polishing shop and DID NOT wear gloves or preferably gauntlets in front of a spindle, you would be shown the door by the boss sharpish, hand and eye protection being part of the safety wear, and often face masks too, depending on how grimey the particular job was.
All i can say is you guys are well hard to be able to polish bare handed and must have crocodile skin on your hands…
