    Cleaning router bits

    What is the best way to clean built up wood tar or resin from router bits. I just came across some that are pretty caked up and have been that way for some time. Thanks much, Jim.

    some people soak em in simple green. I find that Easy Off foaming bar b Que cleaner works great. you just spray it on and watch the foam take it all away.

    We now divide our time between southwest Florida and southwest Vermont.
    I use CMT Formula 2050 Blade and Bit Cleaner; works well.

    The pessimist says it's half empty.
    I say the glass is twice as big as it needs to be.

    One more issue.

    If the router bit has an integral bearing, remove it. The solvents in the cleaner can leach out the lubricant in the bearing. Sealed bearings are not immune to this.

    I use the CMT cleaner. I've had the one pint bottle for over ten years; it isn't even half empty and I use it for saw blades as well. Good stuff.

    I simply spritz some on, wait a minute or two, then use a fingernail brush (or any stiff bristled brush, but these are inexpensive) to brush off the debris, dry it with compressed air and move on.

    I do what John does but I use "L.A. Awesome" from the 99cent store.

    In front of my router table is a small rack that holds my lift crank, collet wrenches, depth gauge and a nylon brush. When I raise the motor to remove a bit after use, I use the brush before I loosen the collet to remove the bit. This doesn't work well if I have left the bit to set overnight or anything but, right after use, pretty much everything brushes right off.

    I have reduced my wet cleaning of bits by a factor of 10 by spending 3 seconds with the brush right after use. I also put a drop of oil on the bearing before I set the bit onto a bit of paper towel stuffed into the compartment I keep them in. I haven't trashed a bearing in a couple of years.

    Arm & Hammer Washing Soda (no, not baking soda.... different chemical) usually found in Laundry aisle of Grocery stores (Or maybe in SWMBO's Laundry room already)

    Mix up a warm stiff solution and soak a few minutes and then Tooth brush clean (either an old brush or her brush will do) Wipe dry and hit with a little WD40 wipe dry.

    You will find the edge seems sharper as that goo builds up on the cutting edge as well as the leading "Gullet"

    A while back there was a discussion about Simple Green (I used to use it till someone posted a disclaimer from Simple Gree company warning not to use it for carbide blades.

    Oven Cleaner is too Caustic and has been traced to carbide bond failure, besides, it is too expensive, it stinks and really burns when you get it on small cuts.

    Cost wise the Oven cleaner is the most expensive, Simple Green is next and Washing Soda is Cheap. My washing lady also uses it to presoak and super clean my nasty drawers. (ever sense she found my stash in her cabinet)
