How we clean grease traps

1. Access, inspect, and assess

We locate and open your grease trap, checking grease levels, condition, and any signs of overflow or poor performance. This helps us identify what the issues are before cleaning begins.

2. Pump out and clean the system

Using our specialised vacuum equipment, we fully pump out all grease, fats, oils, and sludge. We then thoroughly clean the interior, using high-pressure water jetting where needed to remove stubborn build-up and restore proper function.

3. Final check and clean-up

Once cleaned, we inspect the trap to ensure it’s operating correctly, then safely dispose of waste and leave the area clean and tidy with everything flowing as it should.

Prevent issues before they start and stay compliant

Grease and fat from the kitchen are major contributors to blockages in commercial sewer lines. If you don’t manage grease properly, it can lead to blocked wastewater lines, council compliance issues, and failed health inspections.

Routine servicing keeps your grease trap working as it should, protects your business’s reputation, and helps you avoid costly emergency callouts.

Answering your questions about grease trap cleaning

  • Grease traps require full pump-outs and thorough cleaning which involves completely removing all fats, oils, grease, and sludge, then washing down the trap and checking it for any issues. A quick rinse or chemical treatment usually isn’t enough to maintain a healthy system.

  • Most commercial kitchen grease traps need cleaning every one to three months. High-use kitchens may require more frequent cleaning to prevent build-up and avoid costly problems.

  • Our grease trap cleaning starts from $175 for standard commercial grease traps. This includes a full pump-out, thorough clean, and responsible waste disposal.

    Final pricing may depend on the size of the trap, level of build-up, and site access. We’ll always confirm pricing upfront so there are no surprises.

    A call out fee may also apply for after hours, weekends and public holidays.

  • While grease traps are more common in commercial kitchens, some rural homes and septic tank systems also use them to help stop fats, oils, and grease from entering the wastewater system.

    If your property has a grease trap, regular cleaning can help prevent blocked drains, bad smells, and unnecessary strain on your septic system.

  • Build-up in grease traps is caused by fats, oils, and grease (FOG) from cooking, dishwashing, and food prep entering the system. Over time, these substances cool and solidify inside the trap, along with food scraps and debris. Without regular cleaning, this layer thickens and reduces the trap’s ability to work properly.
