I just got back from the store looking for some Simple Green, but couldn't find any. I picked up a bottle of Mrs. Meyer's Clean Day. It says its an organic all purpose cleaner and the only warning on it is that it is an eye irritant. I got the concentrate Lemon Verbena scent. Should be safe to use to clean a bong right? INGREDIENTS: Water, Decyl Glucoside, Sodium Methyl 2-Sulfolaurate, Polysorbate 20, Sodium Citrate, Fragrance*, Citrus Medica Limonum (Lemon) Peel Oil, Abies Alba (Fir) Leaf Oil, Cymbopogon Schoenanthus (Lemongrass) Oil, Betula Alba (Birch) Bark Extract, Glycerin, Caramel, Disodium Ethanoldiglycinate, Methylisothiazolinone, Benzisothiazolinone
I have a little bit of some 91% iso, but I've had a hard time cleaning the inside of the arms on my perc. I heard with Simple Green you can just fill it up overnight and rinse the next morning.
