My Mom shared this recipe that she uses with me so I thought I should pass it on. It's easy and healthy!
Combine the baking soda and castile soap together in a bowl, and then add the water and lemon juice. You should need about a tablespoon of each but gauge it based on the consistency, which should be a soft paste. Once you have your paste you can scrub the shower and tub clean. Once you rinse your shower should be sparkling!
Bonus cleaning tip – pour some baking soda into your toilet and then add some vinegar! Of course it's not magical, you'll still have to use your muscles and a sponge, but it's a great cleaning solution.
