Another idea from Pinterest is this simple cleaning solution to run through a carpet shampoo machine.
I had to make a double batch to fill the tank on our machine.
I used about 3 quarts of hot water, a half cup of hydrogen peroxide, a good squirt of dish soap and a good glub of vinegar. The original blogger added essential oil for scent. My scented dish liquid was scent enough.
It seemed to work fine and certainly as good as the expensive store bought kind that is more than $10 a jug.
This dish soap is Meyers Lavendar scent. I really liked the scent for carpet cleaning, but I don't much care for it on the dishes. I don't plan to buy store bought solution again so this pin is a great money saver.
I did not take before and after carpet photos. The carpet I cleaned is 14 year old white carpet that is in our 3 extra bedrooms and the big hall that connects them. The carpet is much cleaner after today's cleaning but it hardly looks new. It is better and for now, that is fine.
