Actually that's about the only thing I agree with that he does. Your skin can absorb chemicals through your pores, like how you are heavier when you come out of the shower because your body absorbed the shower water.
Companies that make and the companies that regulate the safety of the chemicals in a lot of household cleaning products determine the acceptable safety level based upon the assumption that people will only use those chemicals occasionally, like a couple times a week or so.
They are intended for HOUSEHOLD use, and not routine professional use. because of this, various household cleaning products may not be completely safe for regular professional use.
Because of this, I always wear gloves when using cleaning chemicals. If you don't, your hands smell like chemicals, and it doesn't wash off right away. It has to wear off. I don't want those chemicals wearing off on my finger foods and going into my mouth. Your hands don't taste good after you use chemicals with bare hands, so I think it's better safe than sorry to use them. That said, the nitrile gloves are what I use, not those big bulky gloves he uses in the video.
I have used those gloves for other things, and they make it difficult to reach into narrow areas and they reduce your ability to feel what you are working on.
Also, it seems to me that many women would not appreciate you having hands that smell like cleaning chemicals.
