I've had many snakes that I've gently handled within a 24 hour period in order to clean out the enclosure. Just be gentle and try your best to avoid sudden movements that might startle the snake. You should be fine.

Since I use tubs I have one ready to go so that I can just transfer the snake from the dirty tub to the clean tub and back into the rack. Most of the time they don't even have enough time to register whats going on before they are nice and cozy again.

As for cleaning her with a cloth this might be best to do after a 48 hour period.
