Another thing I learned about dishwashers is that it is not enough to clean the front. My appliance repairman visited recently and reported that the bacterial and dish soap buildup around the gasket/door seal of my dishwasher is best removed occasionally.
Fortunately, I have a handy dandy grout brush that looked up to the task!
Fortunately, the grout brush combined with some liquid dish soap quickly dissolved the mess and all was wiped away with a damp rag.
We can add this to my list of Things I Never Thought to Clean. My repairman will be so impressed--if ever we need him to return...
