How to Clean Grill Grates After Cooking Fish (Without Ruining the Flavor or Your Grill)

Cooking fish on the grill gives it that smoky flavor we all love, but it also leaves behind a mess — flakes, skin, and that distinct fishy smell.

If not cleaned properly, the next time you grill, those leftovers can stick, burn, and ruin the taste of your food.

Luckily, cleaning your grill grates after cooking fish doesn’t have to be hard or time-consuming.

Here’s a simple, step-by-step guide to keep your grill spotless and ready for your next BBQ.

Why Cleaning After Cooking Fish Matters

Fish is delicate.

It tends to flake and stick to the grates, especially if the grill isn’t well-oiled or hot enough.

When fish residue remains, it creates build-up that can:

• Cause sticking the next time you grill

• Make your food taste like old fish

• Lead to uneven heat and flare-ups

Cleaning your grill after every cook — especially fish — keeps it hygienic, extends its life, and helps you achieve that perfect sear every time.

It’s a great way to prevent delicate fish from sticking and breaking apart while still getting that ideal grilled flavor.

Heat Up the Grill

Before cleaning, fire up your grill for about 10 minutes.

This step burns off loose food particles and softens any stubborn residue.

Whether you’re using gas, charcoal, or pellet, heat makes it easier to remove what’s left behind.

After heating, turn off the grill and let it cool slightly so it’s warm but safe to handle.

Scrape Off the Fish Residue

Once the grill is warm, use a scraper or brush to remove the stuck-on bits.

A wood grill scraper is a great choice because it naturally shapes to your grill grates and won’t scratch or damage the surface.

The Easy Function Wood Grill Scraper makes this step quick and safe.

Unlike metal brushes, it won’t leave behind bristles that could end up in your food.

Move the scraper along each grate line to lift away any fish skin or charred residue.

Soak Grates for Deep Cleaning (Optional)

If your grill grates are especially greasy or smell fishy, remove them and soak them in warm water with a little dish soap and baking soda for 15–20 minutes.

This helps cut through oils and odors.

After soaking, rinse with clean water and dry thoroughly before placing them back on the grill.

Always make sure the grates are completely dry to prevent rust.

Brush Away the Remaining Bits

For any small particles left behind, a bristle-free brush is another safe tool.

These brushes use coiled wire or mesh to clean without sharp metal bristles.

The Easy Function Bristle Free Grill Brush is designed to clean between grates and remove stubborn residue safely.

It’s a solid choice for those who grill fish often since it helps remove oils that cause odor and smoke buildup.

Neutralize Odors

Even after cleaning, fish smells can linger.

To remove them naturally:

• Use vinegar and water (1:1 mix): Spray the grates while they’re still warm and wipe with a clean cloth.

• Rub with lemon: Cut a lemon in half and rub it directly over the grates.

• The acidity helps break down oils and deodorizes the surface.

• Burn off with heat: After wiping, run the grill for another 5–10 minutes to burn off any remaining residue.

These quick steps ensure that your next batch of burgers, veggies, or steak won’t carry a hint of seafood.

Oil the Grates Before the Next Cook

Once your grill is clean and cool, apply a light coat of oil to the grates using a paper towel or cloth.

This prevents rust and makes it easier to clean next time.

For fish in particular, this step is key to preventing sticking.

Keep a Routine

The easiest way to keep your grill fresh is to clean a little every time you use it.

A few minutes of scraping after cooking fish can save you a deep clean later.

Make it part of your routine — right after grilling and before shutting the lid.

If you grill often, tools like a wood scraper or bristle-free brush are worth keeping close by.

They make cleaning faster, safer, and more effective.
