Just a quick note to let you know that the purple rags are the best cleaning tool I have ever used. I have textured floors in the tubs and showers of all three bathrooms in my home. Nothing, not even a cleaning eraser would get all the grime out of the texture.The purple rag did it with just water! Soap film and hard water spots come off the glass shower enclosures with nothing but water and a purple rag. I was skeptical when I first read about the rags, but now I am a believer!
