I often ask myself , “Which would be better, powder form or paste?”
Activated charcoal is so fine and messy yet a paste is the opposite. After testing both products for a month I have to say that powder form is best. I found it removed stains much better than the paste and also made my teeth look whiter. The only negative is the mess but to combat this I placed my jar on top of a piece of kitchen roll. If any of the powder spilled, it was collected onto the paper, was easily folded up after use and threw into the bin.
