Pros: No petrochemical residue; biodegradable; no chemical fragrance; smells nice; TONS of bubbles; effective on grease
I love this dishwashing liquid. All those mainstream kinds that derive their fragrance (and their suds, and everything else about them) from weird chemicals smell terrible to me now - and the scent clings to my hands and sponge for ages.
Fortunately, Trader Joe's would never do that to me. When I use this dish soap, I don't have to worry about friends with chemical sensitivities. Or what weird invisible residue I might be eating off the plate afterwards. It comes in lavender and in orange; I think the orange one is particularly effective on grease, but that might just be my perception because I know that orange oil is great for that. Both smell good; not too strong, just a pleasant smell that comes from essential oils.
The best part about this soap, in my opinion, is that it makes FANTASTIC bubble bath. I toyed with a long line of costly bubble bath gels and foams and balls before this, always struggling to find one that didn't have weird chemicals and didn't cost a ton of money. I finally had to admit that none of them stood up to Trader Joe's dish soap.
A few squirts make a nice long-lasting foam; a lot of squirts make a huge foam head on the bathtub. And it's ridiculously cheap at three dollars a bottle. I could never find regular old bubble bath in a bottle this size, and certainly not at the same cost and with the same big white fuzzy piles of bubbles. And it lasts a long time... at least, until I get in the bathroom with it!
