Can anyone help me with this. I had the dishwasher masked off 2.5 feet up. Everything above the plastic is now dulled. The chemistry was either Modern Stone Easy Etch or Stone Pro quick clean. I know I did not spray and chemistry onto this dishwasher. There is not spots or drips. The color change is very even. The only thing I did different on this job was I didn't use my pump up sprayer, bad gasket wouldn't hold pressure. So I used by battery sprayer. I didn't spray full force but it was a little stronger then the pump up and sprayed a cone pattern. The other really odd thing is the discoloration didn't show up for 3 days. What caused it and most importantly what can I do to fix it. I am really hoping I don't have to buy it.
