How do you soften a basketball?

i have a spalding infusion basketball and it is hard as a rock, when i dribble it , its not like a regular b ball. its pumped correctly and its hard in the grip. it bounces like its flat but everything is fine with it|||1st bounce it as much as possible that will soften it 2nd let a tiny bit of air once a week for 3 weeks only that will do it and remember just a tiny bit|||if it bounces like it's flat, you don't have enough air in it.....|||Buy a new one. The rubber on yours has deteriorated beyond help. Cannot leave basketballs out in the weather for this reason. Basketball is an indoor sport.|||get a new one for christmas........Merry christmas!
