The Grossest Things We’ve Found While Cleaning (And How to Avoid Them!)

Cleaning can be a rewarding experience, especially when you see the transformation from messy to spotless. But every professional cleaner has encountered some jaw-dropping, cringe-worthy messes that you wouldn't believe unless you’ve seen them firsthand. At Maids of Livermore, we’ve seen it all—and we're sharing the grossest things we've found while cleaning (along with tips to help you avoid similar disasters in your own home).

1. The Forgotten Fridge Catastrophe

The Gross Find: Imagine opening a refrigerator only to be greeted by mold-covered leftovers from years ago. We're talking about science experiments gone wrong, with food turning into unrecognizable, fuzzy blobs of green, black, and white.

How to Avoid It:

• Do a quick fridge check every week.

• Label leftovers with dates and toss anything older than 3-4 days.

• Wipe down shelves regularly to prevent spills from becoming breeding grounds for bacteria.

2. The Mystery Under the Couch

The Gross Find: What happens when you don’t move your couch for years? We’ve found everything from petrified food, dust bunnies the size of small animals, to (brace yourself) long-forgotten pet accidents that went unnoticed.

How to Avoid It:

• Move furniture and vacuum underneath at least once every few months.

• Use a flashlight to check under large items during routine cleaning.

• If you have pets, be extra vigilant about inspecting hidden areas.

3. The “What Is That Smell?” Situation

The Gross Find: Foul odors with no obvious source often lead us to the most unexpected discoveries. We've uncovered rotting food tucked behind appliances, moldy towels stuffed in closets, and even dead insects hiding in dark corners.

How to Avoid It:

• Address strange smells immediately instead of covering them with air fresheners.

• Regularly clean behind and under large appliances.

• Keep closets ventilated and check for damp items that may be harboring mold.

4. The Overflowing Garbage Disaster

The Gross Find: Overflowing trash bins are bad enough, but we've encountered garbage that had been left so long it became its own ecosystem—complete with maggots and an odor strong enough to clear a room.

How to Avoid It:

• Take out the trash regularly, especially if it contains food waste.

• Use bins with lids to contain odors.

• Clean and disinfect garbage cans weekly to prevent buildup of bacteria and grime.

5. The Dreaded Drain Disaster

The Gross Find: Clogged drains filled with hair, soap scum, and gunk are bad enough, but we've discovered drains completely blocked by mystery sludge that looks like something out of a horror movie.

How to Avoid It:

• Use drain covers to catch hair and debris.

• Pour boiling water down drains weekly to prevent buildup.

• Regularly clean bathroom sinks, showers, and tub drains to keep them flowing freely.

6. The Pet Hair Explosion

The Gross Find: Homes with pets can quickly become overrun with fur, but one house we cleaned had enough pet hair to fill an entire vacuum bag… multiple times. It was embedded in carpets, stuck to walls, and even inside light fixtures.

How to Avoid It:

• Brush pets regularly to reduce shedding.

• Vacuum floors and furniture frequently, using attachments to reach corners and crevices.

• Wash pet bedding weekly to control dander and fur buildup.

7. The Forgotten Food Drawer

The Gross Find: One of the worst surprises? A drawer filled with forgotten snacks, spilled crumbs, and… bugs. Yes, bugs. Ants, weevils, and even cockroaches love dark, undisturbed areas with food remnants.

How to Avoid It:

• Regularly clean out kitchen drawers and cabinets.

• Store food in airtight containers to prevent infestations.

• Wipe down shelves and drawers to remove crumbs and spills.

8. The Mattress Mystery

The Gross Find: Mattresses can harbor some unpleasant surprises. We’ve uncovered stains of all kinds, dust mites galore, and even signs of bedbugs in extreme cases.

How to Avoid It:

• Use a mattress protector to prevent stains and allergens.

• Vacuum your mattress every few months.

• Flip or rotate your mattress regularly and inspect for signs of pests.

9. The Hidden Mold Problem

The Gross Find: Mold can grow silently behind walls, under sinks, and around windows. We’ve uncovered black mold lurking in hidden spots, posing serious health risks to homeowners.

How to Avoid It:

• Check for leaks under sinks and around windows regularly.

• Use a dehumidifier in damp areas like basements.

• Clean bathroom tiles and grout to prevent mold buildup.

10. The Carpet Catastrophe

The Gross Find: Carpets can trap dirt, spills, pet accidents, and even bacteria. We’ve pulled up rugs to reveal dark, sticky patches that had soaked through to the floorboards.

How to Avoid It:

• Vacuum carpets regularly and schedule professional cleanings at least once a year.

• Blot spills immediately to prevent stains from setting.

• Use area rugs in high-traffic zones and wash them frequently.
