How to Clean the Hood Filters of Your Food Trailer

If you operate a food trailer, cleaning the hood filters isn’t just maintenance — it’s about safety, efficiency, and health code compliance. One of the parts that gets dirtiest — and often overlooked — is the exhaust hood filter.

These filters trap grease and airborne particles to keep your trailer from smelling like fried food all day and, more importantly, to keep your mobile kitchen safe. But if you don’t clean them regularly, they can become a silent danger: fire, smoke, bad odors, and loss of efficiency.

At The Fud Trailer Company, we don’t just build your kitchen on wheels — we give you tools to keep it in top shape.

Today, we’ll teach you how to clean hood filters for your food trailer step by step.
And yes — it’s easier than you think!

Step 1 – Carefully Remove the Filters

Before getting your hands dirty, make sure the hood is turned off and cool.
Safety first!

Locate the metal filters (they usually have tabs or clips) and remove them gently.

Pro Tip: Wear gloves.
Some edges can be sharp, and you’ll avoid direct contact with the grease.

Step 2 – Soak Them in Hot Water with Degreaser

Fill a deep bin or tray with hot water. Add a commercial or kitchen degreaser to loosen up the built-up grease.

Why is soaking time important?
Let them sit for 20 to 30 minutes. This softens the grease without needing to scrub aggressively.

Step 3 – Scrub with Sponge or Brush

Use a green scouring pad or stiff-bristled brush to scrub the filters. Focus on the corners and grooves.

Extra Tip: Rinse with hot water.
This removes residue and helps ensure a deep clean.

Step 4 – Let Them Dry Completely

Rinse thoroughly and let them air dry.
Never reinstall them while wet.

Step 5 – Reinstall the Filters

Once dry, put them back properly.
A poor installation can affect the suction power of your food trailer’s hood system.

How Often Should I Clean the Filters?

It Depends on Usage

• If you cook daily: once a week

• If you operate seasonally: every two weeks

Don’t wait until they’re black or dripping with grease.
Prevention is key.
