You've been doing the absolute opposite of what you're supposed to!
These things are designed to be under pressure, when they're not under pressure the seals start to lift and shink... that's what causes leaky magazines.
Keep your mags under pressure!! (I keep my mags full.. some people debate this, but I've had mags that were only partially full start leaking.. but my full mags are still doin' just fine)
