Battling Grease Trap Odours: Tips & How PuraAir Can Help

Grease traps are essential for any commercial kitchen or food service business, but without proper maintenance, they can quickly become a source of unpleasant, lingering odours. These smells are typically caused by the buildup of fats, oils, and grease (commonly referred to as FOG), and if not addressed, they can become more than just a nuisance — they can pose a health hazard and damage your brand's reputation.
5 Ways to Control Grease Trap Odours
1. Clean the Grease Trap Regularly
Routine cleaning is the first and most crucial step. Depending on your usage, schedule a thorough cleaning at least once a month. Heavy-use kitchens may require more frequent cleanings to prevent FOG buildup and control odours.
2. Use Hot Water and Degreaser
Flushing the grease trap with hot water and a strong degreaser breaks down stubborn grease layers and kills odour-causing bacteria. This should be part of your deep-cleaning routine.
3. Add Bacteria-Based Cleaners
These biological treatments introduce safe, effective bacteria that actively break down FOG and neutralise smells. They’re eco-friendly and a smart way to maintain grease traps between physical cleanings.
4. Check the Venting System
Improper or blocked venting can cause odours to escape into your kitchen or dining area. Ensure your grease trap is properly ventilated to direct odours safely away from customer-facing areas.
5. Install an Odour Control System
Odours often persist when all the above measures are taken this is why PuraAir has so many contracts all around Australia to effectively neutralise odours in grease traps. It may be time to upgrade your odour control strategy – and PuraAir has the experience and expertise to tailor a solution to your needs.
