I’ve got a home carpet cleaner but we need a professional deep clean. I know there are cleaners like Chem-Dry, waterless, etc. etc. But what really works the best?

Thanks!

We have only had to clean once since our carpet is newer but Wife wanted to use Zerorez. They don't use chemicals and cleaner told me you could drink the cleaning water they use..dont know if I would but that was how sold he was on the natural cleaning of the product. They are self contained, bringing their water on the truck, never hooking up to your house.

We were very happy with results and its still holding up.

I have always heard that when you clean with chemicals, the carpets pick up and retain all the gunk that would normally just be vacuumed up.

I have used Stanley Steamer for years at my business. Completely self contained and they do an amazing job on our commercial carpet. They also do hard floors. They steam our tile floors and we are always amazed how well they clean the grout.

No location in your profile, but if you're in my area, email me and I'll set you up with one of my rental units. I have had customers tell me that this machine pulled an amazing amount of dirt out of a carpet that had been cleaned by one of those van-mounted services.

Very kind of you but we are about 2300 miles apart. A bit much unfortunately.
