I cleaned a Triexta, aka Smartstrand carpet and it was interesting. The customer told me it was this new fiber and all she had to do was use water to clean up spots. So, I walk into her living room and see this beige stuff that was covered in these little gray spots.... everywhere (except under the furniture). I presprayed it with MB Redline and it was STILL hard to clean. It took quite a few wand passes to really get those spots out. It looked good when I was done, but I was concerned of overwetting so I bonnet-dried it. Is the best way to clean this stuff is to just treat it like an Olefin? It was very soft to the touch I will say, and it supposedly never needs protector. Has anyone else dealt with this kind of carpet?
