Looking for a heavy-duty Natural Polishing DIY Tub & Shower Scrub?

Living in hill country if you will, we have hard water. I mean seriously hard water. When we installed a new water softener a few years ago, we had to spend a day without a softener after uninstalling the one that wasn’t doing the job.

Or so we thought

… It turns out it wasn’t doing that bad of a job. Without the softener, our water was straight up orange! And all that iron in the water made it smell like blood. I had to brush my teeth with distilled water that I had on hand for making skincare products and stuff.

Long story short, our shower, sinks, and a cast iron bathtub can really acquire hard water stains. Maybe you’re wondering the same – “How can I get my bathtub white again?” This DIY tub and shower scrub does the job without harsh chemicals!

For everyday bathroom clean up or let’s be honest, in between deep cleanings – I use my Daily Natural Shower Spray to help keep everything white and clean.
