racks
At the very least, I would open the dishwasher door and let any remaining moisture escape at the end of a cycle. Letting racks sit in the moisture laden environment any longer than they have to be, would only accelerate potential rust in small hairline cracks/imperfections in the rack's coating.
The racks are quite warm when the cycle terminates. The residual heat should expel any moisture trapped in scoring in the rack's coating.
I personally always use heat for drying, but that is just my preference. Do what you think is right. If you ever see any small pinpoint rust spots beginning, you can always switch to heated drying. If you don't opt for heated drying just open the door slightly after the cycle and I think you will be fine.[this post was last edited: 5/28/2024-19:28]
