When you’re using homemade laundry soap you can ruin your clothing. I know this from personal experience, but lets take a little bit deeper look into why.
If you use soap on your hands in the kitchen or bathroom sink you’ve probably had to deal with soap build up or soap scum.
That’s happening to your clothes, and worse… your washing machine which we’ll address in the next heading.
Every time you wash your clothing soap build up buries itself inside of the textiles. This build up can create a water repelling effect which might be why your reusable towels aren’t super great at absorbing water, but can also leave an oily residue behind.
