Great tip.
All my career I've always made it a habit to wash my hands when it comes to applying the LSP and removing it but never once shared that in a post, so thanks for adding this to the thread.
For the grunt work of removing swirls and such it's not a big deal but when you go to the last step, even when working by machine, take a moment to wash your hands and clean-up a little, same thing when it's time to remove you LSP, make sure your hands are clean and then to some level try to enjoy this last step procedure.
