Here's what I do with my Maverick:
After use, wash with soap and water. Dry. Put back in plastic sleeve (don't bother with the lid), toss in toybox.
Here's what I do with my silicone toys:
Wash with soap and water. Dry. Toss in toybox.
Have had no problems. I've had the VixSkin for over a year, and the silicone toys for up to 10 years. That's why I love silicone.
