Not exactly a hard-hitting topic, but still applicable to those trying to live efficiently. This NY Times article talks about how most people use way too much soap in their washing machines and dishwashers, which is both wasteful and can shorten the lifespan of the appliances. How do you tell if you’re using too much soap?
Take four to six clean bath towels, put them in your front-loading washing machine (one towel for a top loader). Don’t add any detergent or fabric softener. Switch to the hot water setting and medium wash and run it for about five minutes.
Check for soap suds. If you don’t see any suds right away, turn off the machine and see if there is any soapy residue. If you see suds or residue, it is soap coming out of your clothes from the last wash.
“I’ve had customers that had to run their towels through as many as eight times to get the soap out,” Mr. Schmidt said, who lives in Indiana
I’m pretty sure I’m guilty of this. I would imagine too much soap also makes clothes more irritating to the skin.
