Some folks do not like the "No soap" deal and drying them is pretty important and can be hard, unless you know a few tricks.
I have used Climax burst on all my Fleshlights with no ill effects so far, just stay away from harsh soaps and super hot water. As far as drying goes, I have turned mine inside out many times, but I only turn it inside out from the small end and only about 3/4 of it. This keep the entrance from tearing and allows me to dry pretty much all of it. You can use a hair dryer on no heat too. Another way is to place the sleeve part way in and stand it up in the big cap with the small end down. This allows gravity to help dry it and lets air flow threw it too.
My only complaint with all my Fleshlights is I wish they were tighter, the material is so soft that it can be hard to feel the texture. Of them all the clear ones feel the best and seem to be firmer than the flesh tone sleeves.
