Hard water stains have the ability to make even the nicest shower doors look dingy and straight out of a barely-cleaned motel room.
Our tip? Make a natural epsom salt solution to scrub the stains away.
What you'll need —
- 1 Cup Epsom Salts
- 1/2 Cup Baking Soda
- 1/4 Cup Soap (We recommend our Castile Soap!)
- Cotton Cloth
- Paper Towel
- Mixing Bowl
What to do —
- In a small bowl, mix together the epsom salts, baking soda, and soap.
- Work the ingredients together to form a paste.
- Scoop a handful of the mixture onto a clean cotton cloth, and work onto a dry hard-water stained surface in circular motions. (Like when you're cleaning your face!)
- Let sit for 3 minutes.
- Lightly scrub in circular motions with the cotton cloth once more.
- Rinse with warm water, and wipe with a paper towel (you don't want new stains forming!)
The science —
Ok cool! You did it! Here's how. Hard water stains (the bad guy) form when hard (aka mineral-rich) water evaporates, and leaves behind the minerals in a film-like grimy residue. The epsom salts (🔍Magnesium Sulfate) naturally soften the remnants away from their surfaces and also can serve as a mild abrasive. Baking soda (🔍Sodium Bicarbonate) is also gritty and can help scrub away the deposits. Soap helps provide cleansing power.
