Does hydrogen peroxide clean pillows?

I'm curious, does hydrogen peroxide actually work to clean pillows? I've heard some people swear by it, but I'm not sure if it's truly effective or SAFE to use on bedding materials. Could you provide some insight into how hydrogen peroxide might affect the fibers and fabric of a pillow, as well as any potential risks associated with using it for cleaning purposes? Are there any alternative methods you would recommend for keeping pillows clean and fresh?
