So all these car gurus will tell you that you need those $1000 machines just to clean your carpets, that is completely false. After being in the industry for 1o years we will teach how to just clean your car carpet in just 3 easy steps with no fancy machines.

1.  Spray The Shampoo – You can find many different types of shampoo on the market, In order to make your own shampoo just take some dawn dish soap in a spray bottle and fill the rest with water, after vaccuming the area of loose debri you can just spray this solution on the carpet, you dont have to spray the whole bottle. 10-12 sprays will do just fine.
2. Get A brush or a Rag And agitate – So after spraying the solution just with the brush scrub the area for a few minutes, make sure to get the corners of the seat where most of the dirt lies
3. Suck the water/soap – If you have a shop vaccum you can easily suck the water from the carpet, but if you dont just take a dry rag or a towel and go over the carpet again, but with this it may be a little damp for a while, so turn up the car heater or park it for a few hours in the sun.

and vallah now you will have clean carpets, ofcourse this technique will not result in professional results but you will be mostly there.
