The sponge has a good marketing gimmick.....the way I see it, EESO is just a another Co with unremarkable products in a sea of green cleaning product......
for example, I've been using Simple Green for decades, it works great on many things, from carpet stains to swimming pool tile (actually works better than the stuff from Leslies Pool Supplies, and like 1/5 the cost), its cheap, and I can buy it about anywhere, like $8 or so for a big concentrated jug that makes many gallons when diluted, and last me easily a couple YEARS.....
how can you beat that????
so, why should I spend more, and jump through hoops trying to find EESO's elusive cleaners, being sold in some MLM scheme????
and there you have it, I have no compelling reason to switch, or, "if it ain't broke, don't fix it".....
