have an 09 audi a4. Wife went and got coffee and one x-large completely dumped onto carpet. Spent evening with hot water extractor and appeared to get all of the coffee up out of the rug.

I am more concerned that the coffee seeped into the pad underneath and I cant get to it without lifting the carpeting up.

Is it possible to easily lift the carpeting to check/clean underneath?

Thanks in advance - all advice is appreciated
