Thread: Looking for advice on brush restoration

I tried twisting the knot loose, but it turns out the cracking I heard was the hairs and not glue. This is where I'm at and will now have to drill out somehow:


edit: Now, I've cleaned out the inside with a dremel and measured. It's about 7mm deep and 20mm diameter. I understand the insides of these are hollow? That's what it feels like. I'll probably drill out the top part and fill with epoxy.

Polished it up with some blue magic and it looks cleaner - but can't get the dirt out of the lettering on the bottom yet. Any tricks to getting in those tiny grooves? Just using a microfiber cloth atm.
