This ramp went through the dish washer. My dish washer has a 5 min quick rinse cycle. I run them through twice. First time I do use a very small amount of soap. 2nd time, no soap, just water. I've done this a few times w/ different ramps. I personally have had no problems w/ the decals. But caution is always advised. Then I dry them w/ a paper towel and proceed to wax the ramps w/ Meguires Caranuba wax. They come out great.
