5 Cleaning Mistakes That Cause Persistent Bad Odours at Home

Persistent smells around the house are frustrating, especially when you feel like you have cleaned everything. Many homeowners do not realise that some habits contribute to lingering smells. Understanding the most common cleaning mistakes that cause bad odours can help you keep your home fresh and comfortable all year round.

5 Cleaning Mistakes That Cause Bad Odours at Home

Even small habits can lead to smells sticking around longer than they should. Here are the top cleaning mistakes that cause bad odours and how to avoid them.

Not Cleaning the Source of the Smell Properly

Masking smells with air fresheners or surface sprays does not remove the underlying issue. Rubbish bins, drains, pet areas, and forgotten spills often hide deep odour-causing bacteria. If the source is not cleaned thoroughly, the smell returns quickly.

Ignoring Soft Surfaces

Soft surfaces trap odours far more than hard surfaces. Carpets, couches, curtains, bedding, and cushions absorb smells from cooking, sweat, pets, and moisture. Without regular deep cleaning, they continue releasing bad odours.

Using Too Much Cleaning Product Without Rinsing Properly

Using too much detergent leaves residue. This residue traps dirt and bacteria, eventually causing unpleasant smells in bathrooms, kitchens, floors, and laundry.

Forgetting to Clean or Replace Air Filters and Vents

Air filters, rangehoods, air conditioners, and exhaust fans collect dust, grease, and moisture. When dirty, they circulate unpleasant smells throughout the home.

Not Tackling the Source of Moisture and Humidity

Moisture encourages mould and mildew. Damp towels, wet carpets, leaks, and poor ventilation cause smells to keep returning.

How to Keep Your Home Smelling Fresh Long Term

  • Let fresh air in daily
  • Wash or steam clean soft furnishings regularly
  • Use moisture absorbers in humid spaces
  • Deep clean drains, bins, and pet areas
  • Wash towels and gym clothes promptly
  • Check vents and filters every few months

Consistency is key. Small, frequent cleaning habits are more effective than occasional heavy cleaning.

What to Do When Cleaning Alone Cannot Solve the Issue

Some smells come from deeper issues such as:

  • Hidden mould behind walls
  • Leaking pipes under sinks
  • Blocked drainage
  • Carpet padding absorbing liquids
  • Persistent pet accidents
  • Water damage
  • Old ventilation systems

If the odour keeps returning, contact a professional cleaner, pest controller, or plumber. Fixing the root cause is the only permanent solution.
