How to Naturally Clean Hard Water Stains on a Bathroom Sink

We have a history, hard water stains and me. When I was growing up there was a time my family lived in an old farmhouse with a well and our water was so hard that it deposited reddish stains on our sinks, tubs, clothes, and even hair. These mineral deposits were hard to clean – even with strong chemical cleaners. I hated those stupid hard water stains!

I can remember one time when I was about 13 or 14 and it was my job to clean the family bathroom. I was determined to get the hard water stains off of the tub and shower. I used one of those scrubby sponges, powered cleaner, and I went to town. After much scrubbing, the tub and shower looked white again! I was pretty pleased with myself. The only problem was the scrubby sponge I used was so abrasive that it completely ruined the finish on the tub and the shower. Oops. (Sorry, mom!)

Needless to say, that experience has stuck with me and I’ve always been super cautious when it comes to cleaning tubs, showers, and sinks. Sure, I want them clean and I do my due diligence when it comes to disinfecting and cleaning off the dirt, grime, and hairs (Does anyone else think stray beard hairs look like… umm…. hairs from other places? Ew, right?). But I’m always hesitant to clean off tough hard water stains. The last thing I want to do is ruin the finish again!

When I looked into options for a good cleaning product, the selection was limited and my standards were high.  For our family, using a strong chemical cleaner isn’t an option we want to pursue. There’s no way I want to subject my kid or pets (or myself!) to toxic fumes if there’s an alternative. But realistically, I wasn’t sure if I could find the perfect scrubbing cleaner.  Let’s be honest, finding the perfect cleaner is like finding the perfect guy…

  • Must be strong, yet gentle
  • Must be good with children (and pets!)
  • Must smell nice
  • Must be all-natural and chemical-free
  • Must get the job done… 😉

Am I right, ladies? 😀

And then I found Scour Off. The product description states:

…It’s a paste, so it doesn’t form dust clouds, yet it gently removes stains other cleansers can’t and is great for cleaning tubs, ovens, sinks, and tiles and it will even remove rust, and is great for cleaning these surfaces: copper, grout, cement, ceramic, and imitation marble… Natural ingredients remove the toughest dried-on splatters and spills, burned-on grease, baked-on food, and sticky messes without hazardous chemicals or toxic fumes.

My bathroom sink is vitreous china, which means it’s a ceramic that has been glazed and sealed – pretty common for modern toilets and sinks. Lately, the hard water stains on my bathroom sink have been preettttyyy bad. What can I say? Deep cleaning the bathroom just hasn’t happened much lately. I blame the tiny human in my house that needs 24/7 supervision. And for whatever reason, I have been dreading that bathroom sink. It’s one of the things I’d rather not clean. Give me a pile of laundry or a stack of dirty dishes any ol’ day! I know, I know. I’m weird.



I used a wet rag and just a small bit of Scour Off paste. The tiniest bit went a long way! I’m always surprised by how efficient this cleaner is.

Unedited side-by-side comparison. Ooohhh yeah!
  • Scour Off is made from natural mineral abrasives and biodegradable cleaning agents. It does not contain chlorine, bleach, or dye.
  • Wide-mouth jar makes it easy to use.


I used maybe 1/2 teaspoon of product total to clean the sink. At less than $10 for a 9 ounce tub, that means it costs me pennies to clean this sink! And there were zero fumes and zero mess. My kid was running in and out of the bathroom and even grabbed the container of Scour Off at one point. I didn’t let him have it, but there was no need to freak out since this stuff is all-natural. Yes! Mama needs all the non-freakout moments she can get these days!


I think I’m in love. So glad to have a cleaner that is safe, that works, and doesn’t ruin the finish. :)
