FREE: The Complete Soapmaker, by Norma Coney

If you mean another book about soapmaking, no, I don't.

It doesn't seem to have any; just some liquid soaps that seem to be basically hand cleaners. Just do an internet search; here's a couple that came right up;
Homemade Dish Soap
Do you ever wonder if you can make homemade dish soap? Yes you can. It is actually quite simple. Here are two easy dish soap recipes for you. They will leave your dishes sparkling.
Homemade Dish Soap Recipe #1
2 cups of Castile soap
1 tsp lemon juice or white vinegar
1/2 cup of warm water
Pour all ingredients into a cleaned out old dish soap bottle and shake until well combined. Give it another good shake before each use. The lemon juice or vinegar helps cut through the grease on your dishes.
Homemade Dish Soap Recipe #2
This version takes a little longer to make, but is even more frugal
1/4 cup soap flakes or soap shavings (any bar soap will do)
2 cups water
1 tsp lemon juice or white vinegar
Get out a sturdy sauce pan. Pour the water and soap fakes in and slowly heat it over medium heat. Stir the mixture and keep heating it until all the soap flakes melt into the water. DO NOT let the mixture come to a boil. Turn down the heat if needed.
Allow the soap mixture to cool a bit, then stir in the lemon juice or vinegar. Keep it sitting in the pot until it is completely cooled, then pour it into an old dish soap bottle.
With either of these two homemade dish soap recipes you can add a few drops of your favorite essential oil to make them smell better. I find that if I use the lemon juice, I don’t need the essential oil. Bottled lemon juice works just fine.
