Query: If you have a front loading washer, buy this ! No more musty smell

After years of having a smelly front loading washing machine and trying so called cleaners from Tide and others, this actually worked. A few detergent scoops of citric acid, boiling water poured into the drum and the machine set on wash. After the wash cycle was completed, I stopped the machine, let it sit with the water still in the drum. Finished the wash cycle in the morning and drained the clean out hose and lint trap. After repeating this again, no more mildew, musty odor! ! ! This big bag of citric acid is handy because I also use this in the dishwasher in the main wash cup with detergent in the pre wash cup for spot free glasses.
