Hi! I got a Hoover Steamvac. My carpets have gone at least 2-3 years with no cleaning. I have been working on one room. I have completed gone over it 7 times now. I wait about a week in between for the carpet to dry. The dirty tank is still pulling nearly pure-black water from the carpet. I don't know if I should just accept that and give up or just keep going at it until it's clearer water. Do you think it will ever get better or will I be wasting my time if I keep going at it? |

Have a pro with a truckmount clean it first then your Hoover will do just fine maintaining it. Or simply just keep cleaning until the water clears up. But you run the risk of over-wetting and damaging your carpet. ------------- Kleen Kuip Supply Mart Inc. http://www.kleenkuip.com - New & Used Professional Carpet Cleaning Machines, Restoration Equipment, Training, Service and Supplies |

if it isn't mold in the underpad...what couldl it be...
when the last time you cleaned the machine out???
personally I think your carpet is wet for 3 or 4 days... it needs to dry in 24 hours anything more than that causes mold..
exactly how long does it take the carpet to dry...
with a small machine like you're using it will take days if you do more than one pass on the carpet..
the black has to come from somewhere

You do not need to keep cleaning the carpet until the recovery water is perfectly clear. It is quite common for the water in the waste tank to remain dark even after several cleaning passes. Carpet can hold a surprising amount of deeply embedded soil, old cleaning residue, pet contamination and fine particulate matter. Some of that can continue releasing into the recovery water even when the carpet itself is already much cleaner. The important thing is to watch the condition of the carpet rather than just the colour of the waste water. If the carpet looks clean and you are no longer removing significant soil, continuing to make wet passes can do more harm than good. Too much water can lead to over-wetting, slow drying, wicking, browning or even problems with the carpet backing and subfloor. A few additional dry extraction passes are usually more useful than repeatedly adding more cleaning solution. Best Regards, KingCarpetClean  |
