How do you get bubble bath soap out of carpet??

My son spilled a full bottle of bubble bath on our carpet. I can't figure out how to clean it. When I get a rag and try to get it out, there is just more and more foam.How do you get bubble bath soap out of carpet??
You need a carpet extraction cleaner (the kind that sprays liquid into the carpet and vacuums it back out). You can use a residential unit, but a larger, rented one will probably get the job done faster. Use only plain, warm water (do not add carpet shampoo), and pour a full cup of cider vinegar into the receiving tank before extracting (the vinegar limits foaming in the tank when the soap is extracted). This can require extracting the carpet numerous times, using plain water and vinegar each time, but you will eventually extract all of the soap. You really do want to extract all of the soap you possibly can, though, because soap remaining in the carpet is sticky and will soil very quickly. You will also want to ventilate the area very well, as all of that extraction will probably soak the carpet all the way through to the padding.How do you get bubble bath soap out of carpet??
Easy. I got jet black paint out of tan carpet this way. First, use a wet dry vacuum to get up as much of the bubble bath as you can. Then pour water on the spot. Lots of water, like a gallon and a half. Vacuum it up with the wet dry vac. Repeat. You'll probably have to do this a dozen or more times but, the soap will come out. When your done point a fan at it and run your air conditioner to dry, and dehydrate the carpeting
