How can I get mildew stains off a down mattress puff?

Question

My friend and I have been camping for six weeks up in Maine. We were just hit by a huge rainstorm, and our pillows and blankets got soaked. We went to the laundromat last night and washed everything to get the water stains out.

We have a down mattress cover puff thing that we sleep on, and it now has mildew stains on it that we can't get off. We tried washing it with bleach, but it didn't go away. I don't really know anything about laundry. Is there any way to get the stains out?

Answer 1

Most mildew stains can be removed during regular laundering if they are moistened beforehand. If a stain remains, test fabric for colorfastness. If color doesn't change, cover stain with a paste of lemon juice and salt. On cotton and linen, make a paste from an oxygen bleach, water, and a few drops of ammonia. Let paste cover stain for 15 to 30 minutes. Flush thoroughly with water and launder again.

I used Tilex bathroom cleaner on my stroller and it worked great. Rub into spot and let sit then rinse .
