I have the prettiest rug for my patio. It's an indoor/outdoor rug and I love the colors. I love the feel. I love the look.
It got gross.
I took it out to the driveway and hosed it off. That didn't do much.
I sprinkled some Comet bathroom cleaner on it and scrubbed it in using the brush I use in the bathtub. I let it sit in the sun for a few hours. I rinsed and let it dry. . . .
If I do it again:
I'll probably go straight bleach and hope it doesn't ruin the rug. Mildew really grosses me out.
