Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

I recently bought a 250mw laser pointer and as I have not made such a purchase before, I need some tips on how to look after the laser. Just simple things like how to store it, what temperature it works best in, how do I clean the lens and stuff. Basically, what the experts on these forums were to do with their lasers.
Many thanks in advance.
