Problems with a car bra and car wax

From Trackpedia

Recently, I applied Turtlewax Platinum Series Liquid Wax on my Porsche 996 and I gotta say, it went on really easy, a little white residue but it looked great and still looks great a couple of months later and several washes later.

I use a Porsche vinyl car bra and it rained with the bra on. We'd a couple of hot days also. I took the bra off the car to wash it yesterday and found the wax was milky under the bra. I've since received quite a bit of advice on the best way to fix it.

I'm currently just leaving the car in the Sun to extract the moisture. After a day, it does look to have gotten better slightly. Time will tell.
