DIY Soap Scum Remover – natural soft scrub alternative



I was recently hired by someone to clean their home naturally, and I had the pleasure of cleaning one VERY yucky tub & shower! I can’t even tell you how a shower would have so much black and brown grime growing in it.. but I CAN tell you that this cleaning formula worked MAGIC in that bathroom!! It’s stronger than soft scrub, and made using only TWO ingredients that are so natural you could eat them. But I don’t recommend it…

This is my go-to formula for soap scum, mold, limescale, toilet bowls, and many other REALLY tough jobs in the kitchen and bathroom.


Supplies :

  • baking soda
  • castile soap – I use Dr. Bronners and I LOVE the lavender scent, but any castile soap will work. :)
  • bowl & sponge

Directions :

  1. In a small mixing bowl pour in about 2 tablespoons of baking soda, give or take.
  2. Next, mix in enough castile soap to form a paste. This is not a science so just make it thick like the consistency of luscious icing.
  3. If it’s too thick, add more soap. Too runny? Add more baking soda.
  4. When you have it a nice consistency, simply scoop a dollop of it with your sponge and start scrubbing!

To scrub this shower, I used a homemade cotton scrubbie sponge and it worked fabulously. Of course, it does take a little elbow grease so you get a free workout and in the end you will rejoice in the success of a fantastically clean shower!!

  1. Thank You. I have been looking for this homemade things for a long time. Any suggestions about wood floor mopping – what sort of natural things to use? Also, how did you make that homemade cotton scrubie?

    • Citrus & vinegar is really good for wood floors. In a spray bottle of some sort put 1 part vinegar diluted with 4 parts water and squeeze a whole lemon into the concoction. Or you can use an essential oil like lemon, pine, tea tree, orange or sandalwood & add a few drops into it. Then spray your floors and mop as you go! It uses far less water, and NO chemicals!

      The cotton scrubbies were crocheted. I sell them in my online shoppe here –

      I am going to be doing a tutorial on making them in the future! 🙂

    • Let me know how it works out for you! I was TOTALLY AMAZED with the results of this! I wish I remember where I got the recipe from… it was another blogger somewhere out there and I want her to know I am SUPER thankful! 🙂

  2. I love cleaning with baking soda, especially since my kids love baths and I no longer have to worry about harsh chemicals left in tub after rinsing and hurting their eyes and skin. Never heard of the other soap but it looks like it does wonders! Thanks for sharing!

    • Baking soda works wonders on so many household chores! I just love the reaction of vinegar with baking soda and that wild cleaning power. But for really bad soap scum and mildew, I have found this recipe to be THE best!! Castile soap is available at natural food stores and many normal grocery stores. THe most popular brand is called Dr. Bronners. It is just an oil based soap and can be used for dishes, in the shower, laundry, and to make the paste for this soap scum remover recipe. 🙂 Let me know if you try it.

  4. I can’t find Borax and I can’t buy that Castile soap. Is there anything I can replace these things with. I am trying to change over to natural cleaners but I am very limited in what I can get here for ingredients. Please help

    • Hi Angela. The soap scum remover I make is with baking soda (not borax) and castile soap. This is what I have found to work best for me. You could try with just baking soda and water. Baking soda is a cleaner and has a wonderful scrubbing property because it is very gritty. You can find it in the baking section of your grocery store. Castile soap can be found online, through amazon or another site. The main things I use the borax for is laundry and dish washer detergent. In both of those recipes you could use baking soda instead. See more natural cleaning recipes here –

      • So glad you all are trying to be more health minded. I get a large bag of ‘Arm and Hammer’ baking soda at Costco for under ten bucks. I use 1/3 cup baking soda to 1 TBS natural castile liquid soap which I buy at, most of their products are organic and they are running a sale on the Castile soap right now. Just mix the baking soda and soap together and place in a wide mouth jar, great for cleaning everything, especially stainless steel. The soda is mildly abrasive, and the soap smells good and gets it foamy clean, YAY!

  5. I’m 8 months pregnant and….ITS JULY! We only air condition our bedroom so a lot of cleaning has fallen to the wayside as I just cant handle the heat and clean. Tonight I really wanted to clean *something* and I figured I could try my hand at the bath/shower again as I could clean it in the buff and wet myself cool as needed. (haha) Anyways, the shower had gotten quite nasty as I had not been able to come up with a natural cleaner for it that ACTUALLY WORKS! Although not as bad as the shower in your photo :shudder our shower was getting to the point that my husband and I were grossed out being in there. Sooo, I found this recipe and tried it out (I had to sub natural castile based dish soap for pure castile soap) and it worked SOOOOO well! It wa WONDERFUL. I dont think the shower in this apartment has been this clean ever- it wasn’t even that clean looking when we moved in! And I was shocked that it didnt take a fraction of the elbow grease I was expecting to have to put in (being used to putting in a lot of elbow grease for a lot of my natural cleaners. ) I’m just shocked and amazed. THANK YOU!!!! The really cool thing about it was that I *was* able to stand in the shower naked with this stuff and it is not dangerous- you cant do that with a commercial soft scrub! The baking soda dries out your hands a bit but nothing a little coconut oil cant fix. 😉 Oh, and a word of caution for those planning on cleaning their tub while standing in it- this stuff gets slippery!!

    • Congratulations on your baby!!! Wow mama, 8 months prego in the heat of July… I’m 5 1/2 months pregnant now so I’ll be experiencing that 8 month mark in SEPTEMBER! Yeesh… not looking forward to it, lol!
      I’m so so glad that this recipe worked so well for you! I have used it many times with great ease and success. It always amazes me how such a simple little recipe can work so well! I did the same thing the other day – cleaned my shower in the nude and rinsed off while I was cleaning. It was very nice! 🙂

  7. How could I accomplish this if my local store only has castile in bars?
