I'm in the market for a new washing machine because the portal where I add bleach in my current top loader is rusting around the portal--in fact, the rust seems to be around the top of drum rim also. I'm attirbuting this to the stong concentration of bleach. I thought I would try a front loading machine this time around and my thinking is if I buy such a machine that has a plastic portal for adding the bleach and a stainless drum, I will eliminate this rusting problem or will? Your help in making the right decision would be much appreciated.
