This DIY soft scrub is a simple, non-toxic alternative to store-bought cleaners—and it actually works on tough bathroom grime. You only need a few basic ingredients, and it’s safe for your home, your kids, and your pets.

Store-bought soft scrub cleaners often contain stronger chemicals and/or synthetic fragrances that some people choose to avoid.

Not all DIY soft scrub recipes are created equal, though. Some popular versions online combine ingredients that cancel each other out—or worse, can create irritating or unsafe mixtures.

This recipe skips those mistakes and keeps things effective, simple, and truly safer.

Cleaning bathrooms isn’t exactly my favorite chore (are you with me on that?). And when you’ve got multiple people (especially men?) using the same space… well, let’s just say things can get interesting.

I mean if you have a cleanie husband or at least one cleanie son, then things might be different but let's talk dirt and other “stuff” especially if you have littles or non-littles with bad aim.

Let's just say I do not like cleaning bathrooms, but definitely ones that are mostly used by other people.

That’s where this easy homemade soft scrub comes in—it gives you the extra cleaning power you need without bringing a bunch of questionable ingredients into your home.

I'm not saying it's going to make you happy to actually do the cleaning, but you will like it when it's done.

Is Soft Scrub Toxic?

Some store-bought soft scrub cleaners contain ingredients that many people prefer to avoid—especially when cleaning areas used by kids, pets, or for food prep.

While they can be effective, they often rely on harsher chemicals or strong fragrances that aren’t ideal.

The good news is that you don’t need those ingredients to get a great clean.

This DIY soft scrub uses simple, familiar ingredients that are generally considered safer while still being effective on tough grime. It skips unnecessary additives and avoids combinations that can be irritating, ineffective, or potentially problematic when mixed or stored.

This formula gives you an effective clean without those concerns.

Why Some DIY Soft Scrub Recipes Don’t Work (or Aren’t Safe)

You might notice that some DIY Soft Scrub recipes on the internet have hydrogen peroxide or vinegar in them.

While it sounds like both of these ingredients would add a more powerful punch than just plain old water, there are good reasons why I didn't include them in this recipe, or made them optional.

Why Vinegar Shouldn't Be Used for This Scrub

Vinegar reacts with baking soda, so if you choose to use vinegar instead of water for this scrub, you'll want to make only small batches and use the scrub immediately. If you don't, the result will not be any more potent than just using water, so you might as well save money and just use water.

Why Hydrogen Peroxide Shouldn't Be Used for This Scrub

Peroxide mixed with baking soda makes carbon dioxide so it's possible by storing this mixture (or the vinegar and baking soda mixture) you could break your container.

You also don't want to mix vinegar with peroxide. It will turn into peracetic acid which is corrosive and potentially harmful to you, your kids, and your pets (source).

Other Ingredients to Keep Out of Your DIY Soft Scrub

Just in case you're tempted to use other strong ingredients like bleach or isopropyl alcohol, the fumes from those aren't great for you, so it's best to skip them as well.

How To Use

Put a small amount of scrub on a damp cloth, damp sponge, toothbrush (a toothbrush is particularly good for cleaning small areas like tile grout or around the base and crevices of sink fixtures), or scrub pad. Apply to the surface, then scrub in a back and forth or circular motion.

Alternatively, put some of this all-natural DIY soft scrub cleaner on the area you want to clean, the scrub with a cloth, sponge, pad, or brush.

This tub and tile scrubbing tool is a great option for tackling tough jobs.

Where to Use

Making your own soft scrub is a great way to save money and be kinder to the environment.

AND there are all sorts of places you can use this around the home:

  • showers
  • bathtubs
  • kitchen counters
  • countertops
  • tile floors
  • tile grout
  • stove top
  • kitchen and bathroom sinks
  • bathroom and kitchen faucets and knobs
  • microwaves (inside and out)

Storage

You definitely want to store this homemade scrub in an airtight container. A glass jar like a shallow mason jar or jelly jar works well and that's what I like to use (basically because they're cute. Am I right? I mean, it really is true that mason jars make everything better), but you might choose a plastic container to avoid glass breakage in the bathroom.

These jars are for holding yogurt, but they'd be so cute with homemade scrub in them. Truth is, they'd be cute with ANYTHING in them.

  1. Glad to know it works! 🙂 And that I have all the ingredients on hand. My son is 13 and has yet to clean his own shower. This weekend he takes the plunge. He’ll thank me later.

  2. I make my own cleaning products too! I kind of use the same thing, but I made my own “comet” cleanser.
    It is just baking soda and (optional) essential oils, in a canning jar with holes poked in the lid. I shake it on and the scrub, I also use it with my vinegar based glass cleaner, So basically I shake on baking soda spray on a little vinegar and water and scrub.
    I have no doubt your soft scrub recipe works, because what I do works amazingly well too! It will scrub off gunk and grime you didnt even see was there until you started scrubbing and saw that the “white” sink was not actually white at all until the layer of scum was scrubbed off. The scrubbing too takes very little elbow grease.
    Baking soda is awesome for scrubbing off stuff like that!
    Also I had no idea about acidic things and castille soap, that is really interesting!

  3. I haven’t made this before, but we do the baking soda/vinegar cleaning for most everything. I recently started using table salt to get some of the tougher stuff off the tub, it seems to work pretty well. But, I think I will have to give this a try!

      1. Yes! It works quite well. I also use it for unclogging drains, and cleaning the toilet. Plus, my kids like to watch it all bubble up 🙂

        1. That’s interesting seeing all the comments about the vinegar and castile soap canceling each other out. I think my father-in-law was right…the acid base combo unsaponifies the castile, causing the gunk.

          1. I made that mistake when I first started “natural” cleaning, thinking I was getting the best of everything. I made a batch of an “all purpose” cleaner that had vinegar and dr. bronners, and when I came back to it the next week, it had all separated. So I tend to stay away from mixing too many things now. But I stick baking soda in an old parmesan cheese container and sprinkle that, spray with white vinegar, and scrub scrub scrub 🙂

          2. Heather said she uses BAKING SODA and vinegar. They don’t cancel each other out at all….however you are RIGHT about any type of soap bought or homemade and vinegar, they WILL cancel each other out.

            1. Yes, I know. I’m a little confused now about those comments. It’s possible that something got posted out of order or w/ the wrong time stamp. Obviously baking soda and vinegar react and make CO2 and sodium acetate. They work well together but react immediately.

  4. borax and your favorite dish soap mixed to the consistency of frosting and add some essential oils to your choosing! my favorite recipe!! try it

  5. Hmmm, I’ve just been using baking soda and my homemade knitted scrubby sponge which works fine. Do I need to add in the castille soap?

    1. I don’t know…..we did a little testing here and it seemed that this worked better. Maybe give it a try and let me know what you think :).

  6. I Love this idea and I love that you are willing to say, “I was wrong!” I’ve been buying handmade soft scrub cleaner from Etsy, and I am so into it! But, I really want to give this a try. If I do, I’ll be sure to come back and let you know how it’s working!

    1. Thanks!!! It’s rough to have to come back and admit it, but I sure don’t want you all getting the icky film. Bleh.

  7. I just always use straight baking soda..it’s my go to cleaner now, it gets all the yellow hard iron well water gunk off the tub every time. I use an old shower scrubby just for this purpose. No chemicals no fragrance. Although I would love some essential oils smells, just don’t have any right now. I also use baking soda for my sinks and smooth surface cook top. It’s a great cleaner and cheap:)I was an old Flylady follower..she always said “it’s not the potion but the motion”..always stuck with me.

    1. Thanks! I think this works better than the straight soda, but I am glad you are happy with that!
