I am trying to figure out the best way to clean grime off of a washer. The main problem I have is the top of the agitator and wash tub where the top water level sits. I got the agitator clean with some simple green, a rag, and some elbow grease. The tub however is stainless and the grime seems baked in somehow haha. Any suggestions? Also on washers that are all caked up with detergent scum, what do you use to cut through that, a wet rag just creates a slimy mess!
