Peroxide, H2O2, breaks down into simple water and oxygen gas when it gets exposed to air or sits around too long. Your peroxide might have been outdated, but it was probably tightly sealed and still active. But, even if it's old, you can see that it wouldn't harm your fabric once it is watery, it just wouldn't do the job of bleaching or killing germs any more.
