Ok here is what i did. I put some baking soda and a couple of small squirts of shampoo in a pan of water with the brush in it and boiled if for like 20 minutes. All i had to do was take the brush out smack it against the sink a few times and it got most of the build up off. Than i turn the faucet on spray and sprayed the rest of the gunk out. Worked BEAUTIFULLY!!! Thanks all who responded. I appreciate it.
