How can I remove an energy gel stain from my carpet?
No need for vinegar yet. The stuff is very water soluble.
If you get the carpet too wet, you'll just transfer the sugars to the floor under the carpet.
I'd put a wet, not slopping wet, towel on it, and let it sit overnight. The sugars should be drawn into the towel. It might take several applications. Once you've got most of it, go ahead and attack w a wet sponge/vinegar.
