Getting Stains out of Doll Clothes

I have had a hobby of collecting dolls & doll clothes for over 10 years now.  I have found that using Rit Laundy Treatment White-Wash Stain Remover & whitener for non-bleachable whites has cleaned some really stubborn stains off of clothes as well as the colors did not blend when the outfit was soaked.  I usually only put in the white part of the outfit into the Rit laundry treatment.  Sometimes even on white & red clothing, like silken flame dress for Barbie, the mixture got on the red bodice, but it didn't bleed onto the white and even got out ink stains that were on the white part of the dress.  I have had good success with cleaning multi-colored clothing without the colors running or bleeding into each other.  You can soak for 5 minutes to several hours, but becareful if you leave colored clothing in mixture overnight, there could be color fading then.  Good luck, tell me if this works for you!
