We are excited to announce we will be upgrading our website! The changeover will take place on Thursday June 13th starting at 1 am PST – 4 am EST the site migration will take about 30 minutes, the forum migration will take a little longer. We will update this message with the progression. Thank you, ~The Wicked Edge Website Team
I've never tried to clean my strops. I think there will always remain some particles which will screw up your intention. Clay wrote somewhere he used rubbing alcohol on his strops. Not to clean them, but to give them a touch up .
That said, I don't think there'd be a problem if you used a lower grit compound on a strop previously used for a higher grit compound (e.g., use some 1 micron spray on a strop previously used with a 0.5 micron spray). The other way around would surely create problems.
And don't clean your strops too soon, or reapply paste too soon: the wicked edge pastes get truely wicked when your strops have dried out a little and get almost as sticky as chewing gum...
