Dishwasher build up...

“How can I clean soap residue from the inside of my dishwasher ? ”

The most likely cause of this problem is hard water scale and/or over-using dishwasher detergent.

Try these techniques :

First, try not filling the soap reservoir all the way.  You’d be surprised at how clean dishes can get using less soap.  This will help to avoid deposits.

Second, to get rid of the current deposits try using a damp sponge sprinkled with a little dishwashing powder.  Remember, never clean the inside of any dishwasher with anything but dishwasher soap or else you will create excess suds.

Finally, to get rid of hard water deposits, place a bowl of vinegar in the top rack and put it through a normal wash cycle. This should get rid of any mineral deposits. Repeat if necessary.
