It's household. Here's a website that explains what it is: http://www.homemadesimple.com/sites/...issolver.shtml and here is a snippet from that site:

Forget scrubbing. Forget soaking. Dawn Power Dissolver removes burnt-on, baked-on food and grease so you don't have to! And it's more than a powerful grease-fighter. With repeated use, this revolutionary product will help keep your favorite cookware and dishes looking like new again. Just spray it on and let the power foam go to work.

I don't know if it's available in your area, but you can get it online if that's an option for you. Details on the website.
