I thought I would pass this one on. I have been using simple green to clean my blades and router bits for years. My son recently used the Trend cleaner and was impressed so he sent me a bottle. I just cleaned about 15 solid carbide router bits with it and it is way better than my previous method. Almost effortless and they are shiny clean.

Been using Simple Green, also. I did have some stuff I got at Woodcraft many years ago, can't remember its name. Thanks for the tip!

Simple green here as well, I might have to look around for some of that stuff.

Wondering if it would loosen melted nylon stuck to a router bit.  Tried cutting some nylon with my CNC and all it did was melt.  Bit is ruined unless I can shock the nylon off of it.  

Interesting comment on the bottle. It’s says it actually lubricates the router bearings and there is no need to remove the bearings. Not sure about that one.

Trend makes some good products.

 

I've been using L.A. Awesome. for a good while now. Used to be $1/ bottle at Big Lots, Dollar Tree and Dollar General until COVID supply chain inflation. Anyways, either Wood or Woodworkers Journal did an article comparing various speciality and "generic" options. IIRC L.A. Awesome rated much better than Simple Green in their test. I do remember they recommended NOT using Oven Cleaner or any thing with ammonia. Either has an ill effect on the carbide. I use the L.A. Awesome full strength.

Acetone may do the job.  It readily dissolves plastics.

Thanks.   I put the bit in my freezer to see if it might harden up the plastic to where it might pop off the bit.  That didn't work, but i was able to use a razor blade to chip off most of the plastic.  still some between the flutes.   I don't have any acetone on hand but i may have some lacquer thinner.   I've melted plastic cups with lacquer thinner so may give that a try.  Nylon is pretty tough though.
