i'm cheap...frugal. I bought a 8 oz can of spray silicone for about $5 and
soaked my MB blade overnight. all chattering, squeaking, streaking stopped
and I've been using this same blade (heretofore embarrassingly vocal) for 3
yrs now. I clean and wipe down the blade with same silicone spray every
couple of months as a rejuvinating wipe down. guess it acts like moisterizer.

the two spare Bosch blades i bought to replace the bad blade are still sitting
in box, new.
