I will be detailing a 94 acura legend next week. Im only doing the interior as i will be doing it after he gets a repaint, so the exterior wont need to be done. Anyways, i have seen the interior and the carpets look pretty nasty. Alot of set-in stains and spots. I was just wondering what u guys use for stain removal. I was just gonna use some of the otc carpet shampoo but i was thinking that there would be some type of mixture i could make at home for a fraction of the price that would work much better. Also, i have heard the pc can be used for carpet scrubbing. But, i dont know what to use as far as pads or if there is an attachment for cleaning carpets. Any ideas would be great.
