Hi Maria- not sure what you mean by "wet towels" can you explain?

If you mean diy wet spa-type towels you might find this article helpful.
just run them under water
Maria: maybe this will help
We cut a roll of paper towels in half and set them down in a container such as an old plastic coffee container, put a slit in the lid and pull them out one at a time. The liquid you put in the container will determine what you want to do with them. I put Simple Green in mine as it disinfects and deodorizes and is a degreaser too.
