Cleaning dome

Okay stupid question. I did search for half an hour before posting this. We have a hurricane headed for the coast of S.C. I am about 3 hours away but even thos far inland it can get bad with power outages. So I charged all my batteries and checked all my lights. I noticed the dome on a Utilitech I seldome use needs some cleaning. Not really sure what is safe to use. Most of mine are so well maintained. Stupid question so my apologies. Thanks for any help.
