If you dry your sink after you use it every time, you will almost never have to do a serious scrubbing. I use a dishcloth in the kitchen and a washcloth in the bathroom and when they are too damp, use them to wipe down counters and then toss them in the laundry and pull out a dry one.

I use watered down white vinegar to clean just about everything. It works on glass, stainless steel, ceramic, vinyl, etc. It's cheap and is good for people with allergies as well as for the environment.
