Why is My Porcelain Sink Stained, and How Can I Get That Spotless Shine?

As a retired plumber with over 30 years in the business, I’ve seen the inside of my fair share of homes and dealt with every porcelain sink stain imaginable. Rust, hard water buildup, soap scum – you name it, I’ve gotten it out. So if your porcelain sink is looking a little worse for wear, take some advice from an old pro like me on how to get it cleaned up and shining like new again.

Let me tell you, I’ve been around sinks all my life.

After decades in the field, I’ve mastered the tricks for making stained porcelain look brand new.

In this article, I’ll share all my tried and true methods for erasing stains and restoring your porcelain sink. I’ll even give you a few tips I’ve picked up over the years on how to prevent new stains in the future – take it from this old plumber.

Why Does My Sink Get Stained in the First Place?

Now I know no one likes a stained up sink, but let me tell you, it happens to the best of them. Over years of use, sinks see all kinds of grime, minerals, and just plain old dirt that leaves stains behind. Here’s what usually causes the stains I’ve seen in my years as a plumber:

  • Hard water stains from mineral deposits
  • Rust stains from aging pipes
  • Soap scum buildup from daily use
  • Discoloration of the porcelain from wear and tear

But don’t worry, no matter how old your sink is or how long those stains have been hanging around, we can get that porcelain looking new again.

Best Cleaners and Supplies for Porcelain Sinks

When you’ve been in this business as long as I have, you get to know which cleaners work best for tackling all the usual porcelain sink stains. Here are the supplies I always keep on hand for stain removal jobs:

  • Baking soda – This stuff works great as a gentle abrasive. Mix it with water to make a paste for scrubbing away grime.
  • White vinegar – Cuts right through soap scum and hard water gunk. I usually pour it straight onto the stain.
  • Hydrogen peroxide – A milder bleach that whitens and disinfects without harming porcelain.
  • Bar Keepers Friend – This oxalic acid cleaner is my go-to for really tough rust spots and stains.
  • Soft scrub cleanser – I swear by this stuff for scrubbing away daily grime buildup.
  • Sponges – Have some abrasive ones and some soft non-abrasive sponges on hand.
  • Scrub brushes – Help me really work cleaners into stubborn stains.
  • Pumice stone – This gently abrades stains away from porcelain without damaging it.
  • Microfiber cloths – I prefer these over paper towels, they don’t leave lint behind.

With the right supplies and a little elbow grease, you can conquer any staining situation. Now let me walk you through how I’d clean some common sink stains.
