I have seen other posts about this, and wanted to hear what people think.
I recently did a big carpet tile job in a public library. It hadn't been cleaned for 4 years and was possibly the most dirty carpet I have ever seen. I cleaned it using HWE with a porty (ninja) and a power brush. I got tons of dirt out and all the stain, but it seems like I did get some dirt wicking to the surface.
In the end, the people thought I did a fantastic job, which I guess is what counts. But several people will say that they would only use texathem or dry fusion on carpet tiles. But this doesn't really clean the carpet either does it??
So what is the best way to clean rubber backed carpet tiles? The cleaners before had used a rotary system and shampoo, and I think that is why it was so dirty.
On another note, I started carpet cleaning 6 weeks ago, and have now payed back for all my equipment, Ninja, powerbrush, wands, steammate etc. Just an encouragement for those starting up!
