Your kitchen sink is one of the most-used fixtures in your home—and also one of the easiest places for grime, stains, and unpleasant odors to build up. Whether you have a granite composite sink, a classic cast iron basin, or a stainless steel setup, regular maintenance keeps things fresh, sanitary, and functional.
At EcoSpark Cleaning Service, we specialize in deep cleaning homes in Santa Rosa and surrounding areas, including Airbnb cleanings, move-out services, and more. Below, we break down how to properly clean each sink type, plus drain maintenance tips to keep things flowing smoothly.
How to Clean a Granite Composite Sink
Granite composite sinks are popular for their sleek appearance and durability. However, they require special care to avoid discoloration or surface damage.
Step 1: Daily Cleaning
Wipe down your sink with a soft cloth and mild dish soap after each use. Avoid abrasive pads or harsh cleaners, which can dull the surface.
Step 2: Stain Removal
For stubborn spots, use a mix of baking soda and water to create a gentle scrubbing paste. Rinse thoroughly and dry with a microfiber cloth.
How to Clean a Cast Iron Sink
Cast iron sinks have a glossy enamel coating that can chip or stain if not cared for properly.
Step 1: Scrub Gently
Sprinkle baking soda over the surface and scrub with a soft-bristle brush or non-abrasive sponge. For tough stains, make a paste of baking soda and hydrogen peroxide. Let it sit for 10 minutes before scrubbing again.
Step 2: Rinse & Protect
Rinse thoroughly with warm water, then dry the surface to prevent water spots. Applying a thin layer of car wax can help protect the enamel and extend its shine.
How to Clean a Kitchen Sink Drain
Clogged or smelly drains are common—but avoid reaching for harsh chemical cleaners. Here’s how to clean and deodorize them naturally.
Step 1: Clean the Drain
First, remove any visible debris. Then, pour a pot of boiling water down the drain to loosen buildup. Follow with a half cup of baking soda and a half cup of vinegar. Let it sit for 15 minutes, then flush with another pot of boiling water.
Step 2: Deodorize Weekly
To keep odors at bay, repeat the baking soda + vinegar method once a week. You can also add a few lemon peels and ice cubes for a fresh scent and light scrubbing effect.
