These are great for wiping under my hood, truck and door jams after I wash my car. I do not use these on my shiny painted surfaces, not that they will scratch but I don't want to test if they will or will not. They absorb water extremely well and I used them all summer and the box is still full, so I expect three summers of use from this box. I also took out several and folded them to keep in a ziplock bag to keep in my glove box for emergency spills.
