Grill Grates Cleaning featured

Cleaning grill grates is a nasty job, but not if you want your food to taste nasty too!

I’ve heard people say they don’t mind a little leftover grime on their grates,  with the claim that “it adds flavor”. No, this is not a thing. Only lazy people say that. Grease, oil, and marinade get caked up during grilling. After they sit there for a while, they turn rancid and will make your food taste bad. Just clean the grates, it’s not that hard.

You never think of using a frying pan and want to cook something that has left-over gunk and dried sauce everywhere. Well, your grill is pretty much the same principle and should have proper hygiene you need for a fine BBQ.

Let’s talk about heavy metal for a second. Not the kind that you listen to that makes the neighbor’s wonder if you’ll ever grow-up. The kind that gets hot enough to put an excellent sear and crust on your steak. Below well cover everything you need to know about grates, DIY cleaning hacks, maintenance tips, and our top picks for the best grates and cleaning tools.

Common Cleaning Methods

To prove to you just how easy it can be let’s review the three most common methods of cleaning.

1. The Obvious Approach: Brushing

This method works best if it is done immediately after grilling while the grate is still hot. Before the grates cool off, scrape each grate with a brush, both top and bottom sides. You can also dip the brush in water which will create a steam that loosens the grease.  Not only will this make cleaning time shorter, but it will discourage insects from hanging around your grill. Depending on your grate you may need to wipe them down with a cloth after scrapping.

2. The Lazy Approach: Burning

The idea behind this method is simple, get the grate super hot (550° F) until all the caked on grease burns up. You can throw the grates in a self-cleaning oven or simply place some aluminum foil down on top of the grate, close the lid and light up the grill. After about 10-15 minutes all of the grease should be a white powder, simply brush it off and you’re done.

3. The Neat Freak Approach: Soaking

Although, brushing and burning are the standard methods for cleaning, all grates should be soaked at least a couple times a year.

Just fill up the sink or a large bucket with water and a bunch of dish soap. Add a little baking soda and let the grates soak for an hour. Afterward, scrub and rinse.

4. The DIY Approach

You can easily make your own scrubber with a block of hardwood. Use the block to scrub the grates after grilling, eventually, you will carve grooves into the block that fit perfectly onto your grate.

Aluminum foil is another easy DIY scrubber and also a lifesaver if you have to use a lazy person’s grill. Simply heat up the grates, then wad up some foil and scrub away. Let’s jump into some do-it-yourself methods to cleaning up those nasty grates.

DIY Cleaning Methods



After any cooking on your grill, you’ll need to give a general clean up. This is when the grill is still warm but never when it’s hot. Mix in a spray bottle some white vinegar and water. Use about 60 percent vinegar to 40 percent water for the ratio to work best. Spray this generously onto the surfaces you want to be cleaned and wait a couple of minutes.

Use an onion on a BBQ fork. The onion has acids that break down fat and the water inside the onion works like a steam cleaner. Rub-down the grates after cooking and scraping as usual and when the grates are still pretty warm. You can add some salt on the onion’s scrubbing side to get better traction and scrubbing power. The onion can also be sliced thinner to reach between the grills.

Use the fork to angle under the grill edges to remove anything stuck underneath. You won’t need to peel the onion, just slice it with the skin still on. After that, give a generous spray down with vinegar and water mix to wash away the onion build-up. This will further break down oils and fat that has dried onto the metal grill surfaces.

Tin Foil VS Corn Husks

Some people like using tin foil to scrub but there is a better cost-effective solution.

Use dried-up corn on the cob husks. You can split them down the middle or into quarters when they are still fresh. This is so they fit easier between the grates and in tight spots. You can also dip them into the vinegar so they will act as a natural toothbrush that scrubs off the dry stuff easier. Get under the grilling grate too so you don’t have left-over build-up. Then use a wire brush dipped in the same vinegar and water solution to wash down the rest.



Caked on grills will need a strong cup of coffee. Brew up a batch of your favorite mud and put your grill into a washing tub. Pour the coffee over the grill until it’s submerged. Let it sit until the natural acids in the coffee break down the fats and dried-on food. This can take 3 hours of soaking, so sit back and have a cup as well. Afterward, you can scrub off the grill with any scrubby sponge or pot cleaner.

This method is great for cleaning both sides of the grill and should be done at least once per season. It doesn’t matter what kind of coffee you use, but the stronger you make it- the better. Arabica coffee is good to use, and it should be made from coffee grounds on a drip machine.

Vinegar Revisited

You can’t beat the power of white vinegar and water at getting any grill sparkling clean. Put your grills in a plastic tub and fill it up with a 60/40 mix of vinegar and water. Let it sit for 5 minutes and then use a lemon to scrub-off the remaining caked-on grill grate. You could use nearly anything handy such an onion, lemon, or dried corn cobs. This method is especially strong to remove very gunked-up grates in a hurry.

Especially if you didn’t have the time to clean your grill in a while! Not only is this method safe and chemical-free, but your metal also isn’t getting scratched by using scraping tools. The left-over vinegar and water mix can simply be flushed without harm to the environment.

Recommended Bonus Tool: Bchoice Scraper

key chain cleaner


It’s so small it fits in your pocket and can clean your grill too! It’s handy enough to pop the top of your beer if you’re careful enough. Works in any kind of grill no matter which model and has several scraper slots to clean. There are 5 rounded notches and 5 V-shaped notches. If you need something useful to clean your grill, this is certainly the right choice for you.

Why We Don’t Like Brushes for Cleaning Grates


Everybody thinks that wire brushes work best, but in reality, they can be dangerous if not used properly. You need to use a scraper to knock down the dried-up stuff that a wire brush can’t do easily. Like brushing your teeth huh? Not really, since little wire hairs can snap off and stick to the greasy spots you can’t get to. You won’t see it there until it gets in your food. Sending your BBQ guests to the hospital is never part of the plan.

Only use a wire brush after you’ve scraped off all the grease and given the grill a good inspection. Dip your wire brush into water before doing any scrubbing after the grill is free from oil and junk. If the grill is still hot, the water will vaporize and causes steam to remove anything left-over. This will also prevent little wires from sticking to the grill surface too as they’ll drop down into the grill bed.

When is the time to buy new grates?

No matter how it can happen, grates will eventually wear out if you don’t take care of them. The issues of rust, wear-n-tear, and rough cleaning can end them sooner for all the wrong reasons. When you see that the grates are getting too pitted from scraping too hard will be a sign. Rusted to the point they are nearly falling off is another! Perhaps you forgot that the weather damaged them through water and rusting.

When you see these signs, it’s time to get a new grill surface that fits onto your grill. Since this is your cooking table, you better buy a quality metal. If you take good care of that grill, it will last longer without needing a replacement for many decades.

Are rusty grates ok? If so, how much rust?

A little rust is ok since all metal surfaces can oxidize with the right conditions. Even foggy weather will make this happen and you can get a light rusty coating that is easy to clean off. But if you go full Titanic mode and see rust taking on a life of its’ own, your metal might be too damaged. Seeing big rust chunks is not a good sign and that means there’s also a water or moisture problem.

Metal grills naturally react with water and start to break down like everything else. Keep your grill covered and away from moisture.

How to keep rust from coming back?

After any good cleaning coat your grill surface with vegetable oil on both sides. The oil can keep moisture from attacking the metal. If you want to store your grill for long-term over the winter, put your grill grate inside a plastic bag. When you’re ready to use the BBQ again, take them out of the bag and give them a good wipe down with paper towels. You’re then ready to fire-up the barbecue again and start cooking.

Since you don’t have to put them in a bag all the time, always wipe the grill down before cooking on them. Vegetable oil also attracts little bugs, dust, and debris. Clean surfaces work better if they don’t have any kind of build-up. The oil just helps you keep rust from ruining an afternoon BBQ.

About Grill Grates

If there has to be the nagging question that determines what kind of grill grate is better, I’ll admit it’s a jaded subject. The whole issue here is simple when you are cooking anything on an outdoor grill. But it’s one of those things that also will make people go nuts about the specifics on which grill is better. Let’s not forget why grilling on outdoor grates is part of the appeal of BBQ and especially for flavor. So how do grates affect these points?

Each grate surface is designed to keep your meats and foods off the coals, that’s all there is to it. How the grill pattern looks isn’t so much an issue as heat dispersion and access to smoke is needed. If you haven’t figured it out yet that your flavors get better when meat can cook slower with an even coloration on the outside. It also absorbs the smoke and gives a richer flavor than cooking on a stovetop.

But for the sake of giving an idea what grate will be more suited for BBQ grilling, here are the most common kinds of grilling grates you’ll find on the market.

Best Grill Grates

When it comes time to move onto a new set of grill grates, here’s our recommendations.

Cast Aluminum GrillGrates

best grill grate winner

These are special add-on plates that fit into a standard rectangle BBQ set-up, they also have a standard kettle grill model. These grates interlock in sections, you can purchase custom sizes to cover any grill space. They have raised bars that meat and foods sit above with holes at the bottoms of the plates to give airflow and smoke flavor plenty of room. What makes them stand out is they can be flipped over to make a flat griddle cooking surface instead of a grill grate.

Because they’re made from aircraft aluminum, they hold up very well under high heat. Aluminum is excellent at heat distribution so burning your meat is less likely. They are easy to clean with not too much carbon build-up and never rust! Go figure these are the top choice for BBQs

Chrome / Nickel Plated Wire Grates

If you own a standard Weber grill, you’ve seen these shiny cheap grates before. They work well for a while but after a couple of good years of service, they’re ready to toss out. The plating eventually comes off and they tend to rust quickly. Not too much loss, but then again they’re made to be replaced. These grates work excellent since the grate is thin enough to get a good sear on your meat.

Weber/Kettle Grill Hinged Grates

Weber even has a lift-up hinged version so you can add more coals or wood chips while you cook your meat. The only hassle here is cleaning grill grates later on these versions will be a love-hate relationship. Luckily the spacing on this kind of grate means your food won’t fall through the grate so easily.

Stainless Steel grates

The beauty of these kinds of grates is the variety of styles to choose from. You can pick thicker or thinner grate rods though the thinner ones are much better for allowing the heat to get to your meat for cooking. These will last longer over the plated grates but then again nothing lasts forever when cleaning will eventually wear away the metal surface and elements such as water start to allow rust spots to appear.

You can prep them so they don’t rust so easily and once again these are also replaceable. Just look for a good quality Stainless steel that will last longer than cheaper grates. What you put into the cost of quality steel also affects how your grilled food will turn out.

Cast Iron grill grates


If you ask me, these grates can be perfect for getting non-stick grilling if you are very careful. Here’s why this happens and why so many people think cast iron is some magical metal. The surface has a very nice quality of holding cooking oil. It’s iron, so the little imperfections in the metal will allow the oil to remain on the surface evenly. But when you add heat, this changes everything. That oil can burn-off and then you get fat and food sticking to the grate.

You’ll have to clean these more often when the heat is getting too hot. Even though they hold up great for higher heat, they will need scrubbing and oiling after every use. They can be a headache over the other alternatives. If you want to keep it simple, don’t invest in cast iron grates unless you are prepared to do more prepping to keep these grates well oiled and properly cleaned.

  • This is a question? Why do grates shrink? Our grates no longer sit on the middle edges of our grill, so the meat cannot be laid across the grates. The grates fall into the burner when I go to lay the meat on them or when I turn the meat over.
