Frequent use of bathtubs often leads to tough stains. Soap scum, hard water, and bath bombs can leave unsightly marks, and typical cleaning products sometimes fail to do the job.
That's why many cleaning professionals recommend a throwback approach: using Bon Ami powder to tackle stains effectively without harsh odors or toxic residues.
Here's how it can help clean your bathtub effortlessly.
Why Bon Ami Powder is Perfect for Tough Bathtub Stains
Bon Ami is a gentle powder cleanser that employs natural abrasives like feldspar and limestone, along with biodegradable agents, ensuring a scratch-free clean.
Whether you're dealing with hard water stains or discoloration from bath products, Bon Ami powder is the safe cleaning option for your needs.
According to Scott Schrader, a cleaning expert, this non-toxic cleaner is effective without risking damage to your tub. He emphasizes, 'It's very mild and non-abrasive; it won't scratch porcelain or enamel, yet it effectively removes soap scum and mineral buildup.'
Additionally, it's rated 'A' by the Environmental Working Group, indicating a low environmental impact and minimal health risks when used properly.
1. Apply the Powder
Start by wetting the surface of the tub to eliminate loose debris and create a surface for the powder to adhere, suggests Scott. Then, sprinkle a light to medium layer over the stains.
For tougher stains, mix Bon Ami with a bit of water to form a paste. Spread this over the stains and let it sit for 5 to 10 minutes before scrubbing, Scott advises.
2. Gently Scrub
To avoid damaging your tub, Scott recommends using a damp non-scratch sponge or soft cloth. Scrub in a circular motion, focusing on the most soiled areas, while keeping a gentle touch.
A Scrub Daddy Sponge can also help reduce pressure and ease strain on your arm.
3. Rinse Well
After scrubbing, rinse away the powder. If your tub lacks a detachable showerhead, consider using a measuring pitcher or a slip-on tub hose, like the Rinseroo.
4. Dry the Area
Complete the process by drying the bathtub to prevent watermarks and any lingering powder that could leave a chalky appearance.
A shammy towel makes this task quick and easy.

Common Questions
Can bleach harm a bathtub?
Yes, bleach is corrosive and can damage most bathtubs, often worsening stains. It's better to choose natural alternatives like Bon Ami powder for cleaning.
What causes yellowing in bathtubs?
Yellow stains in bathtubs often result from limescale buildup. Using Bon Ami powder or baking soda can brighten it, but regular cleaning and drying after use can help prevent this.
