they don't smell bad or burn your hands like most strong cleaning chemicals
These things are a lifesaver. I lived in an apartment with a nasty stained bathtub and NOTHING would get the tub clean until I tried these. It took several of them and a lot of scrubbing. My arms hurt afterwards, but it was worth having a clean bathtub. I don't know what's in these, they don't smell bad or burn your hands like most strong cleaning chemicals. Maybe they really are magic.
