Product review (5 stars): Highly recommended replacement!
If you could love such a product!  I always removed and cleaned the bottom of this part of the disposal every couple of days. Since installing this anti-Microbial version I notice that although it needs some rinsing off, it doesn't seem to 'grow' disgusting garbage like the one I removed.  FYI: the bottom of these are where gnats breed if not kept clean, but with this anti-microbial version the problem is greatly reduced.

I clean my disposal interior by putting a couple tablespoons of Dawn in a small glass and run the water into the glass while the disposal runs until the soap is totally rinsed out of the glass.
