This is what I have been using so far (and for bar soap I was using Fels Naptha soap, but want to try it with my owns soap, which might be lard soap): Hot water 1/2 cup Washing Soda 1/2 cup Borax 1/3 bar Soap (grated) In a large pot, heat 3 pints of water. Add the grated bar soap and stir until melted. Then add the washing soda and borax. Stir until powder is dissolved, then remove from heat. In a 2 gallon clean pail, pour 1 quart of hot water and add the heated soap mixture. Top pail with cold water and stir well. Use 1/2 cup per load, stirring soap before each use (will gel).
