This company uses products on your carpet that are organic and plant based, also non-toxic. It is made with ingredients that you can find outside in your garden. I had no idea that those types of ingredients would be effectivein spot removal and carpet sanitization, but they are. My animals mean alot to me and I'm glad that they are safe when I get my carpets cleaned. I've been doing it for the past year and my lil dog is safe and sound and has never had an adverse reaction to the cleaning products.
