Separate the paper towels at their perforations, then stack them on top of one another. If desired, cut the paper towels in half or in quarters.
Place the stack in an air-tight container, such as a large plastic food storage container or baby wipe container.
Pour 3 cups of all-purpose cleaner into the container. The cleaner will be absorbed by the paper towels.
Seal the container using the lid so that the paper towels do not dry out. Whenever you would like to use a wipe, open the lid, remove the paper towel, then replace the lid.
