I was doing a load of wash today. As I was putting the clothes in the machine, I noticed filth build up on the tank and agitator. I use liquid fabric softener which can create sticky residue if used with cold water. That collects dirt and clings to the basin. I regular clean that away, but today I looked a little deeper. I saw that same sticky dirt collected under the rim of the tank. Washing machine tanks are like toilet bowls, which also collect yuck just under the rim.Washing Machine Maintenance Tips I Almost Missed
