Retroclean cleaned a 40 year old tea stain our of a cutwork tablecloth that had been washed and dried several times. The same solution was used for several more pieces of work. That's probably not the recommended, but I like to stretch a penny. Cat urine was in some quilts for over 5 years (I didn't know). It took out the stains and any residual smells. Retroclean also removes yellowing. You can check here using 'antique clean' to search for more thoughts on this product. I am not affiliated in any way, but just a happy customer. It took out rust from pins, too.
