Bought a Bissell Crosswave on weekend . So far surprisingly useful/effective. It came with a small sample bottle of cleaning solution. I went on line to Amazon and ended up buying Bissell carpet shapoo by mistake ( less than a liter ` $25 ) but then relised that the precribed product for Crosswaves was $75 for approximately the same volume. When I compared the ingredients the shampoo contained many of the same ingredients but in a much higher concentration ( and some soap like surfactants as well ). Can I dilute the Bissell shampoo that I have already purchaed or do I have to bend over and spend $ 75 on being sc****d for something that seems to be no more expensive to manufacture?
