I somehow suspect that this is supposed to be a similar to product to Earth Friendly Products' excellent Wave dishwashing gel. It looks vaguely similar to EFP's version in the bottle and the texture is comparable. However, Trader Joe's version doesn't seem to be as effective. Most of my dishes come out clean, but my silverware is typically cloudy looking, and it doesn't do anything for the tough jobs, like my dogs' food bowls with crusted-on homemade wet food that I slacked on soaking in the sink before tossing in the dishwasher. (Let it be known, the dishwashing products I like pass this test.)
It's fine for most dishwashing jobs, it's just not good enough. Any time I have to re-wash things when they come out of the dishwasher, I won't re-buy. It's a big waste of water and effort.
Sad, because the bottle claims it "dries spot free". It's also labeled "biodegradable, phosphate free, chlorine free, removes dried on foods, removes tough stains, built-in rinse aid." If you can't find other eco-friendly options, give it a shot and post here to let me know if it works.
