Plastic sink maintenance

I have a 2005 27rl with the white plastic kitchen sink. The sink is becoming discolored, what is the best cleaner for this sink?

The wife says to use hot water and a cup of bleach,let it sit for a while. this will work if it is coffee,or food stains. But if the plastic is yellowing we don't know of anything to fix that.

This will sound kinda funny but I use car polish on it once or twice a year. This removes the staining around the drain and (maybe) makes it harder for future stains to set in. Mine is still in like-new condition though mostly because we use sink protector mat thingy to keep scratches to a min.

Bravo ScottandGrace...An ounce of prevention.I like that one.

I had mine replaced after two years. It is started to turn yellow again. I think the sun is doing it. I wish I could find a Stainless Sink to replace it.
