My family and I recently moved house and the new house has a large, white, plastic sink in the kitchen. My wife doesn't know what to use to clean it as it gets pretty stained very easily.
Any ideas what's safe to use, and what'll get it clean? She's tried bicaronate of soda, Borax, and dish detergent. They all work to an extent, but are they safe to use, and are they the best thigns to use? Is it safe to use bleach to clean not only the sink but to pour down to clean the drains?
