Traditional heating method: Place the Fleshlight in warm-hot water for 15 minutes until warmed.
Variation: Replace the water every 5 minutes with hot water. You might also want to keep the hot water flowing down the drain, this way your fleshlight stays warm.
Bring a pot with hot water with you and place your lube in it to keep your lube warm, prolonging the warming experiance.
Use a Warming blanket, set it to medium heat and let warm for 2 hrs, the fleshlight keeps warm for a long time.
Try a sealed heating container for faster heating.
Cleaning: Recommendations include everything from simply washing your fleshlight out with hot water to using alcohol as a disinfecting agent every so often.
That concludes todays tips by me, but feel free to leave your own tips. Thanks!
