Pomegranate/Blueberry Stain

Try some vinegar. Saturate the stain in vinegar, rubbing without streaking. Let it sit for a while then use boiling water and or a steamer if you have one. I've used this method for everything from coffee to pink nail polish.

I swear by Kids and Pets in the carpet cleaner section of Walmart! It removes printers ink from the kids clothes as daddy is not always quick to change after work. It works on lipstick, vomit, pet and child accidents and a huge list of other stuff. I've never had a pomagranate/blueberry stain but it got up everything else we have ever tried it on!

Spot Shot took black raspberry stains out of my carpet so I would think it would do the same for your stain.

Have you tried oxyclean or hydrogen peroxide? Get a tooth brush and lightly scrub alternating with a dry cloth. Maybe that will help?

i always use spot shot to clean up spills. it took purple koolaid out of my carpet even though the same koolaid stained my fingers and foot. so it works well. it even takes smells out too. i swear by it. getting the metal container that foams is slightly better than the spray bottle imo, but both have worked fine for me. good luck. i hope you find somehting that works.
