I may try that blue masking tape. My blades spend a lot of time taped up for various operations during construction. When the tape has been on for a while it will leave a behind a horribly gunky mess when removed. The absolute best thing I've found for cleanup is a spritz of WD-40. While we think of WD-40 as slippery like a lubricant, I believe it is technically more of a slovent. It will desolve the tape residue in seconds. The gunk will easily come off by wiping it with toilet paper.
