First off, please don't use Clorox wipes to clean his tank. I'm fairly positive those chemicals are dangerous for the animal. Simply use a diluted solution of 10 parts water to 1 part bleach. Then rinse extremely well with very hot water.
If you only need to keep him somewhere for the amount of time it takes you to clean his tank then simply put him in a pillowcase. Be sure you turn the pillowcase inside out so there's no risk of the snake becoming entangle in any loose threads along the seam. I have heard of this happening. Carefully tie off the pillowcase (just be sure not to get the snakes head! My Milks frantically try to escape as I'm trying to tie their snake bags off. Wouldn't want to hurt them).
