How do I get rid of midew in the kitchen sink?

There are many products to get rid of midew, I find bleach works well.

Chucks correct about the bleach. Most bad smells in kitchen sinks are caused by rotting hair matted with grease from the soap and from rotting food in kitchen disposals Try this for the smell. Tonight before bedtine Take a 1/4 gallon of bleach and pour it down the drain and let set over night. Next morning ,(and this is important) flush out the drain with two large pans of boiling water to loosen the grease and flush the mess out. The bleach will make the build up slippery and began to dissolve it and the hot water will melt the grease and flush the mess away.
This should make your drains smell better. With all chemicals used in drain cleaning proper ventalation should be observed. Good luck, Tom
