I didn't get your message last week! I checked my inbox and it wasn't there, so sorry you've been waiting to hear back from me.

I have always used borax- found on the top shelf of the laundry aisle above the stain removers and such. I have heard others say that they had success with things like Oxyclean as a substitute for the borax. Borax is just basically a laundry booster and so is Oxyclean so I think it would be worth a shot.

I hope that helps!
