People swear by the incredible soap scum-slaying ability of distilled vinegar (heated first) mixed with grease-cutting dish detergent such as Dawn, in equal proportions. If your shower is made of stone, however, the vinegar could damage it. Instead, mix some liquid soap with baking soda until it's the consistency of frosting, says Kris Koenig, CEO of Natura Clean. Scrub it onto the glass shower door with a nonscratch sponge.
Clean the shower door as you're finishing up your shower. The warm water has already loosed up the grime, plus you don't have to worry about getting messy or wet. Use a sponge or foam cleaning pad such as a Magic Eraser, and you won't need to mess around with additional cleaning products or chemicals.
Leslie Reichert, aka The Cleaning Coach, offers this trick for cleaning your glass shower door: Cut a lemon in half. Dip one half in baking soda, then rub on the glass door. "Once you get the glass clean, I like rubbing it with a little lemon oil, too," she says. "The oil will repel the water so the soap doesn't dry on the glass."
Use a toothbrush for scrubbing the metal frame around your shower door. A paint scraper can help get the gunk where the metal meets the shower or door, and a razor, carefully and gently applied, can scrape mineral spots off flat glass.
Squeegee, Squeegee, Squeegee
Prevention is key. "The best thing you can do is squeegee the door after each use," Koenig says. Keep one hanging in your shower to make it easy. "It'll help keep hard-water deposits from building up, so you won't have to scrub so much later," she says.
DIY Daily Shower Spray
Using a shower spray daily builds time between deep cleans. Make your own on the cheap -- and without harsh chemicals -- by mixing 1 cup water, 1/2 cup vinegar, a little dish soap, and 10-20 drops of your favourite essential oil. Keep it in the shower, and spray the glass door down after squeegeeing. (Skip the vinegar if you have a stone-tile shower.)
