The 0.5mm ones from tepe are my faves... but others are available... These come in various sizes Ive been using them for a while now on new belt projects with great success For brass flywheels I get the majority of to goo out, and then dip the brush in thinners (very carefully), and then clean the flywheel. Rinse the brush of in thinners & repeat until its all gone. For plastic wheels I use Isopropyl instead of thinners for obvious reasons. Works a treat.
very smart idea Never thought about dental brushes to clean the melted belt and goo I just ordered it from Amazon . Thanks
So, I tried it today buy unfortunately the brush is too weak for tightly set-in gunk. I had better luck with a safety pin and lens cleaning cloth.
another tip... I get the majority out using a pin as well. Then use the dental brush. Finally, for those super small traces, I soak a length of cotton thread in isopropyl, and then loop it around the offending flywheel and pinch it closed. I then manually turn the fly wheel and tighten my pinch on the cotton. I do this about three times with a fresh piece of cotton each time. Finally, back to the dental brush to give a good clean up.
