When you have a controller, you want to make sure that it is taken care of properly. When you are not using your controller, make sure that it is set on a dry surface. If you have a stand, set it on the stand. Make sure that the controller is away from pets and children. These two do not mix. When the pad needs to be cleaned, you can use brushes or Q-tips to help clean. If you would like to make sure it is fully cleaned, you can use a small amount of rubbing alcohol on the Q-tips. You may also use water. However, if you are unsure of what to do, do not use anything except a dry Q-tip.
