For any kitchen, the grease trap is the last line of defence between your fryers and a blocked sewer. Clean it on schedule and you’ll forget it exists — let it lapse and it’ll remind you at the worst time.
Why the grease trap matters
A grease trap catches fats, oils and grease (FOG) before they reach the drain. In the trap, FOG cools and floats while water passes through. Left in place it hardens into a solid mass that narrows the pipe — which is exactly how F&B kitchens end up with a sewer blockage during the dinner rush.
How often should it be cleaned?
Most busy kitchens need the trap cleaned monthly. High-volume operations — fried-food outlets, central kitchens, food courts — may need it every two to four weeks, while a small cafe might stretch a little longer. The honest rule of thumb: when the combined fat and solids reach about a quarter of the trap’s depth, it’s time.
Signs your trap is overdue
- Slow-draining kitchen sinks and floor traps.
- A foul, rancid smell near the trap or drains.
- Grease visible at the trap lid or backing up.
- The trap is more than a quarter full of FOG and solids.
Why it matters beyond the smell
A neglected trap doesn’t just block your own drains — FOG that escapes into the public sewer is a known cause of mains blockages, and keeping a functioning, regularly serviced grease trap is part of operating responsibly as a food premises in Malaysia. A clean trap also means fewer emergency call-outs and no nasty surprises during an inspection.
Set a fixed monthly clean for a busy kitchen and keep a simple log. A scheduled programme is cheaper and far less disruptive than an emergency jetting job mid-service.
Make it somebody else’s problem
We clean and pump out grease traps and dispose of the waste through licensed channels, and we can set a recurring schedule so it never backs up on you. See our desludging & grease trap service, and if a grease-heavy line is already blocking, our sewer cleaning & jetting clears hardened FOG from the pipe itself.
