Mistake 2: Using Too Much Detergent
Excess suds can hold dirt pulled from clothes and get caught in areas that won’t always rinse clean, like under a collar, leading to bacteria buildup. The remedy: Use only half the amount of detergent that you normally do, then gradually increase that amount if your clothes are not coming out as clean as you would like. An exception: If you have hard water, you may actually need more soap than you are using. Check the recommendation for hard water on your detergent bottle.
