not a big deal until it has more than one built up on it. however when they do build up I do one of two things to get rid of it: 1 put it in a sweat box(shoe box with a warm wet wash cloth or tea towel) usually takes 15 to 20 minutes. or 2 wet a q-tip and gently wipe it across the eye cap. Make sure the sweat box isnt directly over the basking area but keep it warm. This also works great with a poor shed. Good luck and happy herping!!!! Damon
