Here’s an easy, cheap and effective way to clean your grimy shower doors —without a trip to the store
With all due respect to shower curtains, there’s just something about a glass shower door that elevates the otherwise mundane act of bathing to a spa-like experience. That blast of steam when you open the doors, the draft-free oasis when you pull the door shut behind you—sometimes you never want to leave. But when that crystal-clear shower enclosure gets cloudy with soap scum? Not so much.
Even with all the commercial bathroom cleaning products on the market, there’s an even better solution for keeping soap scum off your glass shower doors—and it’s made from a household product you likely already have on hand. We spoke with cleaning experts Jocelyn Garcia, a team starter and trainer at Maid Brigade, and Abbey Waterworth, owner and operator of The Cleaning Rag, to learn the best DIY method for keeping shower glass clean. Read on to learn their proven pro secrets.
What’s the secret to sparkling glass shower doors?
Soap is meant to clean, and it does its job well. But it also does us dirty when it turns into soap scum on shower tiles and glass doors. And if you live in one of the many parts of the country affected by hard water—that is, water that contains a higher concentration of calcium and magnesium—then soap scum is inevitable.
“Soap scum is usually a combination of hard water minerals and oils and product residue,” Garcia says. That combo isn’t always the easiest to clean, unless it’s up against the killer combo of vinegar and dish soap. The vinegar works to break down the mineral part of the soap scum, while the dish soap takes care of the oily part, she explains. “Together, they loosen the whole layer so it can be wiped off instead of smeared around.”

Can you use dish soap and vinegar on all shower doors?
Garcia says to skip vinegar altogether if your glass shower has a protective coating that’s meant to repel water or soap scum in the first place. “Vinegar is acidic and can wear the coating down over time,” she explains. The same goes for any showers that have tinted or specialty glass. “When in doubt, check manufacturer instructions,” she says.
Another word of caution is necessary if you have natural stone around the shower, like marble, limestone or travertine: Keep vinegar away from it, as it can etch the surface, Garcia warns,
