How to Clean Smarter: Answers to Common Cleaning Questions
We’ve gathered some of the most common cleaning questions and broken them down room by room. From the kitchen to your bedroom, you’ll find simple answers, pro tips, and the right products to help you make cleaning fast and easier.

Kitchen
Kitchens can seem intimidating to clean due to the number of appliances, sanitary needs, and other sensitive surfaces. Protecting surfaces while cleaning is key.
Q 1: What’s the best way to clean a dishwasher filter?
A: A clean dishwasher filter helps to keep your dishwasher operating efficiently. To clean:
- Remove the filter and toss any food debris
- Wash gently with soapy water
- Rinse and return to its place
Q 2: How do you clean burnt food off stainless steel pans?
A: For burnt pans or grease stains, a heavy-duty cleaner like Zep Heavy-Duty Citrus Degreaser & Cleaner is recommended.
- Spray the product and let sit for 1 minute
- Scrub as needed and rinse thoroughly
Avoid plastic handles and don’t allow the product to dry on the surface.
Q 3: How do you clean the inside of a microwave?
A: The key to a quick and easy clean is contact time. Allow the cleaner time to penetrate stuck-on food and grease before wiping.
- Allow to sit up for 2-3 minutes for quick clean up or 2-3 hours for a deep clean
- Rinse thoroughly with water
Q 4: What’s the best cleaner for granite countertops?
A: Granite and other natural stones need a gentle touch. Acidic or alkaline cleaners can etch and discolor the surface. Instead:
- Use a non-caustic granite cleaner
- Spray evenly, let sit as directed, and wipe clean
- If used on a food contact surface, rinse thoroughly with water
This will preserve the granite’s finish while keeping it safe for everyday use.

Bathroom
Bathrooms can be tricky to keep clean due to constant moisture, soap scum, hard water, and grime.
Q 5: What’s the easiest way to clean my shower head?
A: Mineral deposits can block water flow over time. To clean:

- Reattach shower head back
This is also a good time to replace the plumber’s tape under your shower head to help prevent leaks.

- Reattach the cover to the fan once dry
Q 8: How do you remove mold from a bathroom ceiling?
A: Mold is both unsightly and unhealthy, tackle stains and growth quickly.

To prevent mold from returning, always use the exhaust fan when showering.
