GUNKY WASHERS
The plastic outer tubs don't get any dirtier than metal ones do and its much easer to clean off. Any one who has cleaned the porcelain tub cover on an old MT or BDWP washer compared to cleaning the newer plastic tub covers knows what I mean, the plastic will look like new with almost no effort. The blue staining that you see in dryer drums is not fabric softener but dye from blue jeans etc. This is caused by washing in cold water, the excess dye is not washed out and when it gets heated in the dryer it stains the drum and other clothes in the load. This problem is also much worse when the dryer has a nearly clogged or very long vent system. The vent problem causes the dryer to get hotter and steamier and to run twice as long to get things dry. You can tell a lot about peoples washing practices by looking in thier dryers, I was working on a KM electric dryer the other day and the whole drum was gray-brown dirty and when you looked at the washer you could see why. Cold water, too little and cheap dollar store detergent and the washer smelled.
