GIY Soft Scrub with Dr. Bronner’s

This GIY trick is the magic of chemistry right before your eyes!

Soft scrub is a great aid to clearing away soap scum, ring around the tub, mold, stubborn water spots on glass.  It’s a great way to shine up your kitchen sink.  You’ll probably find that you keep this bottle just as handy as your Dr. Bronner’s All Purpose Spray.

This soft scrub will remain blended in your cabinet, so you don’t need to remake it every day.  Unless of course, you use it up.  Which you will.  Because you’ll love it, too.

Here’s the recipe from the video all written out:


1 c. Dr. Bronner’s Pure-Castile Soap OR ¼ c. Dr. Bronner’s Sal Suds
3⅓ c. baking soda
1 c. water
¼ c. white vinegar

In a big bowl, combine the baking soda with the Pure-Castile Soap OR the Sal Suds.  Mix it with a fork until well blended and no lumps remain.  Add in the water and mix thoroughly again.  Add in the vinegar and keep stirring until no lumps remain.  (If you’re wondering about the vinegar with the soap, check out the video for an explanation!)  Pour the solution into an empty quart bottle, using a funnel.

To use this, squirt it over the surface and wipe with a damp microfiber cloth.  Rinse with a wet cloth.

(And remember: since these ingredients are totally safe and non-toxic, kids can use them, too!  Hand this bottle over to them and let them scrub away!)

    Add in a few drops of lavender essential oil or a favorite other scent and it’s even nicer!

    I love this! Fun to make, effective to use. Keep them coming!

  • Is the Baby Mild okay to use for this? My understanding is that there is additional olive oil in the Baby Mild. I have a huge container of it and I’d like to use it up (I have found that I prefer the peppermint soap for my showers so I am not using the baby mild like I once was).

    • EricSyre

      Mix together the Baby Mild and the Peppermint (50/50). You’ll prolong your peppermit soap and the scent will still be strong. I’ve been doing that for a year, both with the peppermint and almond scents. Works like a charm.

    • Yes, there should be no problem using the Baby Unscented soap for this.

    Will be sure to try this! I’m sure it’ll be great. Dr B has never failed me on ANY cleaning project. Even got MUSTARD out of clothing once! Have been sold on all the wonderful Dr Bronner ever since.

    What is the shelf life for this mixture? It would be helpful if you could add this information to all your post. 🙂

  • RK

    I made this and it filled 1.5 32 oz bottles so have an empty spare ready or cut The recipe in half. This will last a long time, what is the shelf life?

    • We haven’t tested the shelf life, but in our experience this easily lasts for 6 months or more. The only thing that might happen is that it would dry out or the ingredients would separate.
