This sweater stone is an easy and natural way to remove pilling from your clothes. It is made out of a pumice-like stone and is a healthier alternative to using dry cleaners.
I just got new sweaters so they have not pilled yet but my fleece and microfiber cloths have been pilling. I used the sweater stone to get them out and it did a great job. I could be rougher with a fleece cloth but it didn't do anything but pull the fabric a bit and "scraped" off the pills. It left a grit behind. Next time I will put a towel underneath. The grit fell right off the cloth I was de-pilling and swept up neatly off my washer (where I was testing it). It is doing as I need it to and I haven't even got to the sweaters yet!
