I bought my first bottle of this in October 2007 and just started on my second bottle in June. I cook and do dishes by hand daily, so an economical dish soap is a good thing. The member price is $6.90 for 16 oz. This breaks down to about $1.15 a month. I can't beat that deal!
I usually take claims of concentrates with a grain of salt.
This one proved to worth it. A little bit did last me a several months with daily dish washing use. I must have saved a lot of water from being shipped by using this one.
I miss it terribly, Thought I would try other brands for a comparison. This concentrate out cleans Ecover for sure.
I started using this after I got hooked on the Basic H. Only a few drops washes my pots,pans and other things that are left over after loading the dishwasher. It's also very gentle on the hands.
I find that this is a good bang for your buck. It works well with just a small amount, suds are nice and the smell is fresh. I use it mostly to hand wash my cast iron pots and pans and it gets those clean so I imagine it can get just about anything off with a little elbow grease.
