I noticed recently that a well-known company is now selling a touch-free liquid soap dispenser. I need to say that this is a huge waste of money. No doubt hundreds of people will buy it without thinking. It clearly is meant for the germ-fearing portion of our population. But think: What are you doing when you push down the pump on a liquid soap dispenser? You're washing your hands. Do you touch the soap dispenser after you have washed your hands? No, you don't. So any germs or dirt that end up on the soap dispenser are inconsequential since you are washing them off your hands immediately after they come in contact with your hands.
Don't waste your money. Don't buy the soap dispenser. If you use liquid hand soap, go buy a refillable, manual (the kind you pump yourself) soap dispenser and a huge bottle of "refill" soap. Better yet, to keep that plastic bottle out of a landfill, use bar soap.
