Do Natural Dishwasher Detergents Actually Work?

Over the last couple of months, dish washing in our house has become an experiment of sorts. One of the last household items to go natural in our home was our dishwasher detergent. I was having difficulty finding one that REALLY worked. And you, Dear Reader, gets to benefit from my trial (and error).

The Round-Up:

Palmolive Eco+ - liquid in lemon splash

Planet - powder

Seventh Generation- powder and liquid

Method- Smarty Dish Detergent tabs in pink grapefruit (20 count unwrapped in tub)

Ecover-tabs (25 count individually wrapped in clear plastic)

Let me start by saying, I’m not a fan of powder dishwasher detergent and avoid it. My favorite are tabs because I know the right amount is being used and there is no mess. Liquid falls in the middle.

The Palmolive Eco+ ($2.99 at Fred Meyer/Kroger’s) is basically a greenwashed product. The only ecological benefit of these dishwasher detergent is that it is free of phosphates. IMO, it didn’t clean nearly as well as I expected. This will not be used in our home in the future.

I didn’t like the Planet ($4.59 at Fred Meyer/Kroger’s) powder AT ALL. My dishes came out with residue and most had to be rewashed. It was a trying few weeks. I will not use Planet again.

The Ecover ($3.99 at Whole Foods) tablets worked okay. The tablets had a tendency to crumble somewhat when taken out of their wrap. They would fall in a decent cleaning range, but definitely far from what I experienced with traditional cleaners. While the outer package is cardboard and therefore recyclable, each tablet is individually wrapped. While the wrappers are said to be recyclable, they aren’t in my area and I suspect in most areas. I would use these tabs again if my number one or two choices weren’t available.

My favorites are the Method tabs and Seventh Generation Liquid. Both these products provided a great clean with no noticeable difference from traditional cleaners.

As for what they are made of, Method’s website proclaims “Instead of the nasty phosphates and bleach that make up conventional dishwasher detergent, smarty dish is made from super effective ingredients so green that one of them won a presidential green chemistry award (yes, that really is an award). The blend of mineral cleaning salts, anti-spotting agents and enzymes give smarty dish some serious kick, while the biodegradable and non-toxic ingredients mean no harmful residues or fumes to worry about in your home… and happy fish after they rinse down the drain. The formula is DfE-recognized, with packaging made from 25% recycled plastic. What’s more, smarty dish is specially formulated to be effective yet gentle on glass and flatware to prevent etching.”

Seventh Generation claims, “Non-toxic, No Chlorine bleach or phosphates, No dyes, No NTA or EDTA, Safe for septic & greywater systems, Not tested on animals, Kosher certified.”

The Method ($4.99 at Target) tablets come in a small, squarish, plastic container with a snap close lid. The container is made from 25% recycled plastic and I find it a useful tub to reuse around the house. I would love to see refill packages that use less material since we have no need for a new plastic container every month. Smarty Dish is available in (YUMMY) pink grapefruit and go naked (sans perfume and color). The tablets kept their shape well, without crumble. There was little residue left in the container once the tabs were used.

The Seventh Generation ($4.59 at Fred Meyer/Kroger’s) liquid comes in the traditional plastic squeeze bottle with snap cap. Once emptied the bottle can be rinsed and sent out with recycling (at least in my area, check with your local curbside pick up). I have to monitor the kids on their dish nights to be sure they don’t overuse the liquid cleanser.

  1. Thank you so much for this review of dishwashing detergents! I’ve been suffering through so many different brands and so far I’m disappointed with all of them. I can’t wait to try the Method tabs!

  2. I am new to dishwashers, but we use seventh gen. powder or ecover, and they both work really well.

  3. Trader Joe’s “Next to Godliness” dishwasher powder works well too.

  4. I too just discovered my new eco dishwasher detergent, the Bright Green brand from Safeway. I wasn’t happy with other eco detergents’ stinky perfume or oily residue. I’ve been using Cascade powder, and I like this even better. I don’t know enough about the ingredients to be sure it is totally eco, but it seems to be. The carton is recycled and recyclable, no phosphates, no VOCs, no dyes, no fragrance. I love it, but if there is something bad in it, please tell me what to look for in the ingredients!

  5. Thank very much for the great info. I have been meaning to research re a green dishwasher detergent. You have saved me the effort..Thanks..

  6. I tried the bright green dishwasher detergent. In the past, with products like Cascade Total, I have not had to rinse my dishes, thus saving lots of water. I could just scrape the big stuff off and stick the dishes and pots straight in.
    Bright green requires me to wash my dishes first. If I have to wash them, then what is the point of my dishwasher?

  7. I found your website in attempt to see if others had as much trouble with Palmolive eco as we did. It leaves horrible residue and we had to rewash everything by hand….so much for eco-friendly. I’m excited to try your suggestions of Method and 7th Generation. Thanks!

  8. I have tried all you mentioned as well as bioKleen. My fav by far, washing scrambled eggs off of a stainless steel pan, and greasy residue off everything is Shaklee’s Dishwashing Powder from their Get Clean line. Bummer that you have to order it online, but one bag lasts me almost 2 months. I’m telling you, you can’t find a better detergent, I won’t use anything else!
