The BEST Soap Scum Remover {DIY Picture Tutorial}

May 12, 2014 43 Comments | Disclosure

Monica saw this on pinterest and asked me to try it out and let y’all know how I liked it. It is similar to the Tub/Shower cleaner but you don’t use as much soap. I had everything on hand so I made up a batch.

Here’s what you need:

{PIN THIS}

1 cup white Vinegar

1 tbsp. cornstarch

2 tbsp. dish soap

Spray bottle

soap scum remover-2

Add 1 tbsp of cornstarch to 1 cup of white vinegar. {Don’t add more cornstarch, the first time I made it I thought I was supposed to add 3 tbsp, it was so thick it wouldn’t even go down the funnel, much less spray from the spray bottle!}

soap scum remover-1-2

stir to combine, I used a fork

soap scum remover-5

You can tell it is already thickening up a bit.

soap scum remover-3

Microwave for 2 minutes

soap scum remover-1-3

Add 2 tbsp. of dish soap to your spray bottle. As you all know I prefer blue dawn, I think it is the best, but use what you have on hand.

soap scum remover-6

Take the vinegar/cornstarch mixture out of the microwave and stir a few times. It is more gel like.

soap scum remover-7

Add it to the spray bottle and shake gently to combine.

soap scum remover-4

I decided to try it on my dirty bathroom sink. Looks gross I know

soap scum remover-9

I sprayed {but forgot to take a picture, my 2 year old was trying to help} I let it sit for about 10 minutes then wiped it with a damp washcloth. Everything came right off an it looked nice and shiny.

There weren’t a lot of suds to deal with either {like with the tub/shower cleaner}. I also cleaned my glass shower doors. I have a hard time getting them clean and shiny and getting the water spots off. I sprayed them down then left them for about an hour. I came back and wiped them down with a wet washcloth. I think next time I will only leave them for the most 30 minutes. The cleaner had dried on a bit and I had to apply more elbow grease than I did with the sink. I dumped water on them to rinse after I wiped them and they looked great. {I couldn’t get a good picture of my glass doors so you will just have to trust me.} I liked this cleaner a LOT. I also tried it on my kitchen sink and it was nice and shiny after I wiped it down. I loved that it was just 3 ingredients that I always have on hand. {Are you buying vinegar by the gallon yet? It is the only way to go!! If you haven’t noticed it is in most homemade cleaner recipes.}

  1. So do you just use the dish soap and vinegar and cornstarch mixture or are you supposed to add water to fill the bottle? Seems pretty thick to spray from a spray bottle without adding water.

    • It actually sprays just fine through the spray bottle. You want it to be gel like so it will cling to the sides of your tub or shower. Good luck!

    • Used the cleaner and it works great. I used the dawn, vinegar and cornstarch but can you make a double or triple batch and can you just store it in the cabinet?

  2. I don’t have a microwave. So I will have to heat on stove until gel consistency. Any suggestions as to the particulars? Low heat? Tks.

    • I would do it on medium heat and just stir it constantly. Mine bubbled up in the microwave while it was cooking. Hope it works for yo!

    • I just tried this and forgot to microwave it. Still works, just might not be as gelled. Still clings enough to be effective without cooking it. It even took rust stains off my shower walls! Great stuff.

  3. to be honest…the cheapest and easiest way to clean soap scum is to buy a cheap plastic shower pouf and lather it up with whatever soap you use when you shower. It removes the soap scum quick and easily. You can do it when you shower or at another time, but it really does work. You can buy a super cheap shampoo or bar soap instead if you like. I have tried them all. No mixing…

    • great idea! Thanks for sharing! I will have to try that!

    • I just tried this and forgot to microwave it. It still clings well & WOW does it work! It even took off months of rust stains from our well water!

  4. I’ll be sold when someone uses it on their tile shower and doesn’t end up with a sore neck from scrubbing soap scum. I detest this job, not just because it’s gross, but because it hurts my shoulder and neck!

  5. I couldn’t figure out how cornstarch could be helpful but keeping the cleaner stuck to the walls of the shower? So Helpful! Thanks for the tip

  6. Amanda Gomez says:

    I am letting this sit as we speak on my marble and stone in my daughters bathroom shower. Looks like it’s going to work!!

  7. So do you like this better than ‘The BEST Tub/Shower Cleaner’ or are you sticking to that one? These are great tips! Excited to try it (and bummed I just bought and used a new shower cleaner recently).

  8. I’ve been using the warmed vinegar and Dawn for quite some time and LOVE it! What does the cornstarch do to the equation? Also, I use about half as much Dawn because it was a little soapy when I made it the first time.
    To answer Athena’s question about adding water to fill up the bottle…NO!!!!
    Also as a note, the cleaner works just as good after it had cooled – once it is heated the first time, no need to reheat.

    • I’m not positive, but I would think the cornstarch is just to help it adhere to the surface (especially shower doors) without dripping down.

  9. Anybody have a good one for removing hard water deposits off clear shower door? And for the sink fixtures? I love the dawn, vinegar, cornstarch….works great for the soap scum!!

  10. Did this today, I doubled the recipe because of the big job I had. I did my master ….

    First – let me say I am a LAZY housewife, soap scum doesn’t completely do my shower justice, it was more like soap cement.
    Second – I DON’T SCRUB!

    I have not been able to get our shower door haze free in the 12 years we have lived in our house……except today!!! and no scrubbing!!! This worked much better than I expected on the tile, plexi-glass, mildew, and chrome all is sparklely. I am so so so tickled.

  11. I don’t use the cornstarch, nor do I heat anything up. I do add essential oil, though. Right now it’s a blend of clove, eucalyptus, lemon, thyme and cinnamon.

  12. I hate cleaning the shower stall. I’m excited to try this, sounds just like what I’m looking for. I’ve spent so much money by trying all the different products out there and not finding anything that works.

  13. This is amazing. The bottom of my shower was brown. I cleaner after cleaner that said they would work. No dice, It wasn’t until I tried this that my shower got clean. I am sold. Don’t care much for the smell, so next time will add some lemon juice

  14. Well, it worked well but wow was it stinky~ I don’t have a window in my bathroom so I was gagging! (store bought products would have been worse I’m sure)
    Thanks, it was cheap at least.

  15. I absolutely love this! So much easier than store bought products and I feel I am being green! Thanks for the tips.

  16. Does it have to be Dawn? Or can it be another dish soap like Sunlight? I have a HUGE amount of Sunlight because I can buy it cheap in bulk. I’d like to use that if it works rather than going out and buying Dawn.

  17. I haven’t actually scrubbed yet… my “concoction” is sitting on my walls now. I just wanted to say one thing… USE AN INDUSTRIAL BOTTLE! Don’t be an idiot, like me, and use one of those extra little $1 bottles from the dollar store… they melt! Ha ha ha!

    I really hope this works, as my husband works in industrial work with rust and other black and red chemicals and he’s FILTHY every day he comes home… I cannot keep my shower clean.

    Also, the smell is terrible, so if you’re asthmatic and have twitchy lungs like me, at the least tie something over your face… the vinegar is strong. Here’s to hoping it works!!

    • Stephanie says:

      OMG thank you I thought I had accidentally put bleach in there the smell is so terrible I could barely breath!!

  18. Used this today and it worked like a charm. I hate trying different cleaners and prefer to just use household ingredients (for those who are trying to peddle a store bought cleaner, lay off! Some of us just don’t like to waste money on store bought cleaners when we can mix them at home!) Did take several times tossing water on the shower after wiping to get the last of the cleaner off. Well worth it in my opinion. Also helped remove some of the scum from my fixtures that have been there since before I moved in. I do agree that the smell is strong, but if you leave it on for about 20 minutes it at least dies down before you start wiping!

  19. I got overwhelmed by the steps…so, after scrubbing bubbles did zippo, I grabbed my toothpaste, a.k.a baking soda, and applied it directly and wiped off. Baking soda + water + minimal rubbing = clean bathtub. Works like a charm. Haha! :)

    What’s with all of this BioWorx crap? That guy is getting annoying and his repetitive plugging under different usernames is getting old. He was all over the other post about the best tub/shower cleaner too.

  21. Sloan Jackson says:

    Well… I never thought that would work, but it sure did!

  22. Melissa J says:

    So, I have tried scrubbing bubbles, cleanser (scratched my tub…grrrr), bleach, a kitchen scrubby with other cleaners and STILL had horrible soap scum issues. I admit that scrubbing the tub is NOT one of my favorite things and it kills my back so I always end up waiting TOO long and it’s usually pretty gross. I don’t understand how you stand in a shower and CLEAN yourself with soap and water and RINSE it down the drain, and yet your tub is disgusting…BAFFLES me! lol

    ANYWAY, sorry for the digression. The point being, I have tried everything and nothing seems to work and that is why I hate cleaning the tub! Today, I finally decided there had to have been SOMETHING that would work on soap scum, so I did what everyone probably does…I Google’d it! That is how I found this “recipe” and boy am I glad I did!!!

    Can I just say, SERIOUSLY??? Really, it’s THAT easy to get rid of soap scum? This worked like a charm and yes, the vinegar odor is SUPER strong (use your bathroom fan), but it is no worse than many of the other cleaners I’ve tried. The only difference between them and this was that THIS WORKED!!! Literally, I sprayed it on and left it for about 20-30 mins and grabbed a kitchen scrubby expecting to use some elbow grease, but NONE NEEDED!!! I mean…yes I wiped it down with the scrubby and yes there were 2 little spots that needed another round of the spray, but within 45 mins to an hour I had a clean tub!!!!

    I am in shock and awe at how amazing this works! I might have to google “how to get rid of a yard full of dandelions” next!

    Thank you for posting this. I am SO happy (and not JUST from the fumes!) lol :-)

    This stuff is magic!! I mixed up a batch and sprayed it on the shower doors, let it work for 30 minutes, and it cleaned them right up. I then mixed up another batch, and tackled the tub…magic again. My tub sparkles. I also don’t like to use harsh chemicals, and make my own cleansers. This one is definitely a keeper.

  24. What is the difference between this and the DIY Tub/Shower cleaner?

  25. Does this keep in the bottle for what you do not use or do you make a mixture every time you want to clean?

  26. I made this recipe today could not spray this . In stead I poorer it on a rag an spread it all over now I’m waiting for it to dry to see if it worked or not . Will get back to you soon to let you no .

  27. Just could not spray it from the spray bottle . I got a rag an poured it on . Then wiped all the walls an tub area with it . Now waiting a little to see my results . Will let you no one way or another .

  28. Just could not spray it from the spray bottle . I got a rag an poured it on . Then wiped all the walls an tub area with it . Now waiting a little to see my results . Will let you no one way or another . After waiting for 10 min I rinsed it off an wala it works very well . Did it twice an very clean . Very impressed with the job it has done . I could not spray it so I used a rag an spread it on .

  29. You are my new hero!!! My husband works in an auto body shop so you can imagine what our shower looks like!! I have tried EVERYTHING to get it Clean…you just saved me hours of scrubbing!! THANK YOU!!!

  30. I think you’re getting your pH mixed up. The lower the pH, the more acidic. The higher the pH, the more basic. The lower the pH, the better it would work well with getting rid of soap scum. So citric acid is technically more acid (lower pH) than vinegar. But vinegar and citric acid is so close that it would barely make a difference. The dish soap (surfactant) is what really helps to dissolve it.

  31. Lower pH (acid) is better at dissolving scale. Higher pH (alkaline or basic) is better at getting rid of soap scum. Some cleaners have acids in them but then they are buffered to a higher pH for soap scum. This is why cleaners have a very hard time getting rid of scale and soap scum all in one because one works better at low pH and one works better at high pH. Dawn Dish soap has a pH of around 9. This is high and good but mixing with a weak acid buffers the pH incorrectly.
