Recently I tried removing silver plating from mylar balloons. I used a water solution of caustic soda (used to unclog sewage pipes) to do this. I dissolved a small amount of soda in warm water, and then I dipped the uninflated balloon. The aluminum layer was etched from the balloon in about 2 minutes. Then I washed the balloon in running warm water and left it to dry.
In addition to the nice appearance, I'm surprised how durable such a balloon is... One burst under me with a really loud bang after inflating it very hard
