Hi Chedva, The best way to deflate the inflatable is to turn off the blower and open all of the yellow air tubes. Allow most of the air to escape on its own, and then you can fold the inflatable lengthwise a few times. From there, you can slowly roll the inflatable up like a sleeping bag, kneeling on the inflatable to squeeze out any excess air as you go. To dry the bottom, you can move your inflatable to a dry spot in the yard, and flip the entire thing over (still inflated) so the blower can run for a little while, while the bottom side gets some sun. Many people find that towel drying helps to speed the drying process as well. I hope that helps! Sincerely, Blast Zone Support
