You will notice I use the back of my hand which does not have the same oil issue as the palm. If you are going to use cotton gloves beware of lint. Rust only becomes an issue if the blocks are left wrung together after use rather than taken apart, cleaned properly, and put away. The acids in your hands will rust the blocks.

Nice video. Don't pay any mind to the over critical. If you were woking in a sterile enviroment in a clean room, then yes, gloves and alcohol are the right choice. But for normal use on the floor, I was taught the way you just showed. Wring the blocks together after rubbing on the back of hand to ensure a friction fit, and get on with it. When finished for the day, I always cleaned with alcohol, then rub them down with a clean oil dampened cloth (3-in-1 oil) to get a film on them

By the way, one more thing, the oils from your hands will RUST the gage blocks!!

How can you ensure the gage blocks are clean when you have oils from your hands being transfered to the blocks? Use CLEAN cotton gloves to handle the blocks and use a lint free wipe and alcohol to clean them. This methodology will ensure that your gage blocks will not rust!! If your going to teach people how to do something, please ensure you are training them PROPERLY!!!
