Old Fashioned Laundry Soap recipe
For the best results, please follow the instructions very carefully. This is not difficult, just a precise formulation. You can create a minor soapy explosion and a BIG mess, otherwise.
These measurements are for one 16 oz. bottle of Ithaca Soap Liquid Unscented. It's very important that you use Ithaca Soap Liquid Unscented. The essential oils may cause undesired results (like an explosion, which I have done). I have not done this with any other soap. I have no idea what would happen with another soap. If you try this with another soap and you have an explosion, all I can say is I warned you. It's not my problem. When you do this correctly, you will end up with a creamy white thick laundry soap. It is a little more caustic, just like laundry detergent, so it's not pleasant to touch it too much.
Important!! Do this outside or in a well ventilated room by an open window or door. When you add water to the washing soda, it will off gas irritating fumes for 30 seconds. Keep pets and children away during the mixing process.
Collect all of the ingredients and tools before getting started.
16 oz. Ithaca Soap Liquid Unscented
3 teaspoons washing soda
16 oz. white vinegar
16 oz. water
1 dry plastic gallon jug
Plastic or rubber gloves
Do this in a laundry sink by an open window or outside in a wash basin, just in case you make a mistake. If you do it right the 1st time, there will be no mess. If you do something out of order or not exactly right, it will still work as laundry soap, just not as well and won't be a thick creamy consistent soap.
1. Put the washing soda in the plastic jug.
2. This is the fume-y part, so do not look into the jug when you add the water. Definitely hold your breath.
3. Slowly add the water and gently swirl it around. This will dissolve the washing soda.
4. This is another fume-y part, so do not look into the jug when you add the soap. Definitely hold your breath.
5. Slowly add the Ithaca Soap Liquid Unscented. Gently swirl it around. The mixture will cloud up and thicken.
6. This is another fume-y part, so do not look into the jug when you add the vinegar. Definitely hold your breath.
7. Slowly add the vinegar and swirl around.
8. Leave the jug UNCAPPED and in a ventilated place where it will be undisturbed for 30 minutes before capping.
9 You have successfully made laundry soap (not detergent). Use approximately 1/4-1/3 cup per laundry load.
