There are common paintball problems you will run into from time to time, fortunately most are completely avoidable.

The number one avoidable problem you will run into is when you go to play another game of paintball and you can't see out of your mask. Yep, dirty gear will slow you down big time. Clean all your paintball gear after each game. The clothes you wear to play paintball can become quite ripe if you just wad them up and stuff them into your gear bag. Unless your goal is to have a ring of dirt around yourself like Pigpen from the Peanuts cartoons, keep your gear and clothing clean.

Another common problem is your paintballs are shooting badly. If you haven't stored your paintballs between games in a climate controlled area, chances are they have gotten warped from too much heat or too much exposure to cold weather. Leaving your paintballs is convenient so they are always there when you're ready to play, however they may not work as they once did as exposure to extremes of heat and cold can badly warp your paintballs rendering them useless.

Sand and dirt in your pods is another issue that goes back to keeping your gear clean. Just rinse your pods after each game and you'll be rid of the build up of sand and/or dirt that can seriously degrade the performance of your marker. Ditto for your marker, clean it after every game so it's always ready to play.

In addition to keeping your mask clean, you will need to replace the lens on a regular basis. Additionally, sweat will break down the foam around the interior of the mask. You can slow down this process considerably by cleaning your mask after each game and getting the sweat and dirt out of the foam of the interior. And those are just a few of the avoidable issues for paintballers and almost all of them can be avoided by keeping your equipment clean.
