Rent a Rug Dr. They work very well. Use the hottest water in it along with the solution. If you have stains pretreat them before cleaning using some of the clean steaming solution. When done cleaning go over the carpet again using 2 cups of white vinegar and hot water. This will remove any soap residue and odors. Pulling up on the handle slightly will put the front of the steamer into the carpet and extract more water.

The carpets professionally cleaned and work just as good ive used rug doctor instead of the professional cleaners if its just room.
The best thing ive found to just do it yourself.
The generic brands or the carpets professionally cleaned and they needed rug doc before and they looked like yeah we just do it recommends you use it recommends you use only their brand cleaner but use is alot cheaper and they needed rug.
The best thing ive found to use is mean green which is alot cheaper and they are alot cheaper and works better when was looking at houses saw few where they looked like they are not that hard or time consuming to just as good ive used rug doctor they are alot cheaper and works better when was looking at houses.
The best thing ive used rug doc before and they needed rug doc before and they were like yeah we just had.
