My wife bought a garbage disposal cleaner so I decided to try it out. How well does foam clean your drain? I'd say it does a pretty good job, it won't be spotless but it does do more than just running under hot water and Dawn.
A really nice thing about cast iron porcelain sink is they are so quite the garbage disposal barely makes a sound compared to stainless steel sinks, it makes a huge difference I'll never go back to stainless steel sink.
Yes! Until I renovated the kitchen in my 1920 craftsman I'd only had stainless sinks. I put in a 36" Kohler Whitehaven and the red Insinkerator Evolution. When I run it, the running water actually drowns out the disposal (ha! Pun!). I can only tell it's running by the vibration or if I turn down/off the faucet. It's wonderful.
