I bought a small storage bin with a lid and I store them there until next wash. I live in a small apartment and I don't have issues with a smell.
If you are looking for reusable pee pads, I highly recommend T.Bumpkins pee pads (
Washable and reusable dog and puppy pee pads, belly bands, and diapers by T. Bumpkins & Co.). She is also a member on this forum and offers a discount. I had her pee pads for about 2 years now and could not be happier. They are environmentally friendly (don't add waste to landfills) and are extremely well made. Also, I notice that my dog consistently goes on her cloth pee pads when traveling while with one time use ones she tends to miss.
