After trying the scrubbers I found that I don't particularly like these for cleaning.... BUT I found another awesome use for them... I cut them in half and soaked them overnight in liquid fertilizer, then placed them into my pots when I repotted my houseplants. They are fabulous for drainage, they stop the soil falling out, and they'll break down and become part of the organic matter. Despite that not being their intended use, I'm still stoked with the product.
