I was cutting some thick stuff yesterday -- some glued up elm and beech scraps. Not sure which one was the culprit but boy the tablesaw blade started cutting slower and even smoking a bit.
Today I dismounted it and gave it a bath in this resin remover stuff from LVT ... pour it on full strength and scrub at it with an old toothbrush. Then rinse it with water and dry it carefully. The end result is a sharp clean blade. I've owned and used this for the past few years and I'm amazed every time.
I'm just totally impressed with this stuff.
Clean your blades! Maybe they aren't so dull after all!
