Just recently I received a panicked call from a client of ours. They had purchased a cushion back vinyl floor from us at the beginning of 2011 and their daughter who had visited over the holidays had discovered that it was covered with a grey film. They thought that it was wearing poorly because their daughter had to scrub the floor for hours to get about half the grime up.
I asked what they had been using to clean the floor because I thought it odd that a quality floor would act that way. And of course, they were using a wet Swiffer-Jet. You see, the soap that Swiffer decides to put in their cleaner leaves a soapy residue which just collects dirt, dust, and grime.
So, because they had limited mobility, I decided to go out and help them clean their floor and show them how to properly keep it clean. Boy, I had NO idea what I was getting myself into! I spent TWO HOURS scrubbing their kitchen floor (which wasn't a large space) to get rid of about 10 months worth of residue and grime!
So, PLEASE, PLEASE NEVER use a wet Swiffer Jet or similar tool to clean your floor! Instead, always talk to your flooring consultant on how to best care for your floor and I personally HIGHLY recommend Armstrong's Once-n-Done vinyl and ceramic cleaner!
