I took the quilt and soaked it in my bath tub with a little synthrapol and a couple of tablespoons of dawn dish soap. After 24 hours,I rinsed it and put hot water in the tub with about 1/2 cup of retro clean( I get it off the internet). I swished it around in the tub two or three times a day,just letting it soak....for 5 days. ( thank goodness we have a shower). Then,I put it in my washer( it doesn't have an agitator) on a short,cold rinse and spin cycle. All the yucky,smelly,yellow discoloration,plus the old stains came out. It is very good quality fabric to start with,which helps.
