At Costco, I decided to get the Dawn Ultra Advanced Power, and man it knocks the socks off of grease, with just a small dollop on a sponge. While my cooking is simplistic and I wash sparingly in large batches, I don’t eat out often and I’ve only used a 10th of the 2.66L bottle in 2 months.
If you don’t use a sponge then I think any dishsoap will do, so long as you can tolerate the smell.
