dremel tip cleanrs

You could soak them in lacquer thinner, MEK or Tenax to disolve the plastic off them.

I don't know if it would affect the burrs or not but I wouldn't think so.

Maybe you could sent Micro-Mark and email and ask them.

This works great!  It's a soft stone-like manufactured material that abrades the stuff clogging the bit, but doesn't damage the bit.

My thought is, why use a diamond burr for plastic? 

There were designed to cut hard materials. Get a steel bit and slow the Dremel down to get the desired results.

Mainly because a single steel bit could be 10-15$ but the whole set of diamond ones I bought were 13

Diamond burrs are abrasive in action; metal or carbide bits cut.  Different functions and uses.

These are $8 for a set of four:

With a different collar size in your Dremel you could use standard drill bits as well and the collar will not cost you but a couple of dollars.

I trust micromark not to put out crappy products like that, eveything I have purchased from them has been top notch, and if I do get shrapeneled, they will get laywered

It's still a good idea to ALWAYS wear safety glasses when using a Dremel.

You only have one set of eyes.
