I would like to get some opinions from anyone familiar with teh Maas cleaning products. I purchased 2 tubes (kind of expensive) after reading about them in a magazine. I bought the product to clean all my brass knobs in the kitchen. I feel like I keep cleaning the knobs over and over again. No matter how many times I clean them, very black tarnish comes off on the paper towels as I clean. I could seriously clean one knob for several minutes, and black keeps coming off as I add more polish in an effort to remove what I assume must be tarnish. Is this product a gimmick? I feel as though I will never get these solid brass knobs really clean. And the thing is, I did not think they were in terrible shape when I bought the polish. Just thought I would give it a try over what I can buy in the grocery store.

What have others experienced with this product? I would appreciate some feedback. Thanks
