Summer Bathroom Deep-Cleaning Checklist to Prevent Mold
Bathrooms are a mold magnet in the summer—thanks to warm showers and poor ventilation. Without regular attention, mildew creeps into grout lines, under sinks, and even behind toilets.
What to clean and how often:
- Scrub grout and caulk lines with an acid-based tile cleaner every two weeks.
- Wipe down shower walls and doors after each use using a squeegee or microfiber cloth.
- Disinfect high-touch surfaces like faucets and handles weekly.
- Empty bathroom trash bins and clean with disinfectant spray every week.
- Deep clean exhaust fans monthly—dust buildup slows airflow and traps humidity.
- Launder and dry bathmats, towels, and shower curtains at least weekly.
Let TopClean handle your deep bathroom clean!
“How do I stop mold from growing in my bathroom?“
Keep humidity under control, clean surfaces regularly, and use mold-resistant products like caulk and paint.
Basement and Crawlspace Dehumidifying Tips
Basements and crawlspaces are notorious for mold thanks to cool, damp conditions. Dehumidifying these areas is key to prevention, especially during the humid Colorado summer.
Tips for moisture control:
- Run a dehumidifier continuously when humidity is above 60%. Aim for 40–50%.
- Install a vapor barrier in crawlspaces to block ground moisture.
- Seal cracks in foundation walls with waterproof caulk or hydraulic cement.
- Use a hygrometer to monitor humidity levels in real time.
- Keep basement windows closed on humid days to prevent moist air from coming in.
- Don’t store cardboard boxes or fabric directly on the floor—use plastic bins.

“Is it normal for a basement to be damp in summer?“
Slight dampness can happen, but persistent moisture is a red flag for ventilation or foundation issues.
AC Unit Drip Pan and Filter Maintenance
Your air conditioner is supposed to keep things cool—but if you’re not maintaining it, it can actually contribute to mold growth.
Here’s what you should do:
- Inspect the AC drip pan weekly. Empty any standing water and check for cracks.
- Flush the condensate drain line monthly with a 1:1 mix of water and vinegar.
- Change your air filter every 30–60 days—especially during peak summer usage.
- Check for musty smells when the unit kicks on. That’s an early sign of mold inside.
- Have your system professionally serviced at the start of each cooling season.
If the drip pan is regularly full or leaking, that’s a major warning sign. Mold can grow there quickly. TopClean helps with cleaning tricky HVAC areas, too.
“Can mold grow in an air conditioner?“
Absolutely. If not maintained, mold can form in the drip pan, ducts, or filter—spreading spores throughout your home.
