First of all, this does the job. However, you can expect to get something that more powder based than granules. This is different than other absorb products. I guess that’s the whole point, this product is different. The product is also very abrasive. For concrete, this is a feature because you can rub it into something like oil to help lift it out. I would not use this on shiny floors unless you can contain it because you run the risk of spreading around abrasive powder. As for reusing the product: you better have a “used bin”. You wouldn’t want to put this back in the bag. Speaking of the bag, I wish it were a bit thicker and potentially had a zipper close. Your best bet is to have a bin for “new” and “used” and empty the content into a bin and not try to use it out of the bag. Overall, different and effective.
