so im trying to get the mold(mildew i think) stains out of what i think is silicon rubber wristband. I left it in my swim bag for a week with wet swim gear, and now there are mold stains on it. I got some of them off but cant seem to get the rest off. I’m iffy on using bleach since there is writing on it in black and i don’t want that to come off. Any tips/is bleach safe? I’m soaking it in some simple green(cleanign junk) right now to see if that helps.
