My dishwasher is corroded with dish detergent... I have put vinegar in bowls on the bottom of the dishwasher and this has helped but the dishwasher still has a thick layer of dish soap that needs to be removed so the dishes aren't covered. I have also raised the water temp. to 140 degrees which has helped with the dishes being cleaner... How can I remove the rest of the residue??

Do you have hard water? And wt kind of dish soap are you using? And how old is it ? It sounds like build up from hard water and soap being used try some frozen orange juice this ahs more acid in it and should take more of it ouit you will also need to scrub it good if you have a lot in there if that does not work I would put some clr in it spray it aorund in there a few times and then dum a bunch in and run it dooing this a few times should get rid of it all
