Hi Mike ..If you look at the ingredients in your laundry soaker you will probably find that the active ingredient is Sodium Carbonate..not Sodium Bicarbonate,but sodium carbonate...That is the best grease killer and probably works on rust too..with electrolysis..
Any laundry soap with that formula,sodium carbonate will do..
Grandma was using that 100 years ago by the name of washing soda..great stuff..I use it mixed up in a spray bottle around the oven..and stove..takes off grease that has been burned on with ease..
Love the stuff and cheep..that is the kicker.
