It's a good recipe and works as far as I can tell. Took the smell of gas off my hands after over-filling the boat.
However, a story I read said not to use the 3% peroxide that you can get in a little brown bottle in the store because it has a slight smell all of it's own, but to go to a pool supply company and guy a gallon of their oxidizer stuff...which is 27%. IF you do this, it then has to be diluted down from the 27% to 3% buy using a 9/1 ratio with distilled water.
I mix mine in a container like this bucket. It has an air vent on top...which you need in the first couple of days as the items mix and produce gases. It also has a spout at the bottom to fill your field bottles. Lastly, it does not let in light which will render the product useless after a short period of time.
The recipe and directions are on here, but the search feature is not working at the moment.
Here is the bucket.
