Is there a substitute cleaner for Kirby carpet shampoo?

I found one and I would just like to share it. It works just as good if not better than the Kirby dry foam shampoo. Please test a small area first. (This recipe is for shampooers that use dry foam cleaner)

Mix all ingredients in a large bucket then lightly stir to mix. Add the WATER first to cut down on all the bubbles.

3 quarts WATER

3 Tbs DISHSOAP

1 Tbs WHITE VINEGAR

1/2 tsp AMMONIA

If you have any stubborn spots you can pre-treat with any window cleaner.
