Recently one of my clients asked me an unusual question, "Can you use Windex Glass Cleaner for carpet cleaning"? I immediately said no and asked why he would ask such a question. He said that the last carpet cleaner he had hired told him that he uses Windex Glass Cleaner on all of his carpet cleaning jobs.
First let me state for the record that S.C. Johnsen & Son, Incorporated, the makers of Windex Glass Cleaner, do not recommend that you use this particular product on your carpets and for good reason. Windex Glass Cleaner is comprised of (3) ingredients - about 90-95% water, 1-5% isopropanol (alcohol), and 0.1 - 1% ethylene glycol n-hexal ether. These three ingredients, when combined, make ammonia with a pH level of 10.5 - 11.0.
If you were to ask Mohawk and Shaw, the two largest manufactures of carpet, they recommend that you have your carpets professionally cleaned every 6 - 18 months using a cleaning agent with a pH level no higher than 9.0. If you use a cleaning agent with pH level higher than 9.0 you will void your carpet's warranty and possibly ruin your carpet. The high pH and the alcohol in Windex will eventually make the carpet fibers brittle. Kind of like split-ends for your hair. Just like your hair needs to be rinsed with a conditioner carpets also need to rinsed with a conditioner that will return the carpet's pH to 7.0 leaving it soft and fluffy.
When asked by the client why I thought the other cleaner would use Windex Glass Cleaner to clean carpets my response was "Drying Times". The alcohol in Windex evaporates water, when exposed to air, creating faster drying times.
The next time you hire a "professional" carpet cleaner make sure that they right type of cleaning chemicals for the job. If you have questions about this or any other cleaning matters email me at firstname.lastname@example.org or give me a call at (916) 525-2456.
