Here’s my recipe for dish soap:
1/2 bar Zote soap
1/2 cup washing soda
1/2 cup borax

Grate bar soap( I used a food processer) use 1/2 of the bar, place in a sauce pan with 4 cups hot tap water.

Cook until all soap is melted – add soda and borax, stir until dissolved. place a large bucket( I used a 5 gal. one) into sink and put about 3 gal. hot tap water.

Add soap mixture and stir well.

Next day stir well and put in bottles(I used water bottles) and label.

I put 1/2 bottle of $1.00 Dawn into it to make it suds, and I also added 1/2 cup white vinegar for grease cutting.

Add scent if you like. I scented mine with watermelon! The kids love it! Zote soap is from Mexico and Big Lots sells it for 80 cents a bar. I used the pink bar.
