How to Extinguish Charcoal Grill: Quick Comparison
Method Overview
When you want to put out a charcoal grill, you have three main methods to choose from. Each method works differently and has its own strengths and weaknesses. Here is a quick table to help you compare:
Method | Safety | Speed | Convenience | Grill Longevity | Charcoal Preservation |
|---|---|---|---|---|---|
Suffocation | Very High | Slow (up to 48 hrs) | Easy | Excellent | Yes |
Water Dousing | Moderate | Fast (minutes) | Moderate | Poor | No |
Natural Burn-Out | Moderate | Very Slow (hours) | Easy | Good | No |
Suffocation means you close the lid and vents to cut off oxygen.
Water Dousing means you pour water over the coals to cool them quickly.
Natural Burn-Out means you let the coals burn out on their own with the lid open.
Safety
You always want to stay safe when you extinguish charcoal. Suffocation is the safest way because you do not touch the hot coals or create steam. Water dousing can be risky. Pouring water on hot coals creates a lot of steam, which can burn your skin. Hot embers may also splatter. Natural burn-out is safer than water dousing but still leaves hot coals exposed for a long time.
Safety Note:
Each year, about 20 people die from carbon monoxide poisoning caused by charcoal grills. Over 300 people go to the emergency room for CO poisoning from charcoal grills. Always use your grill outdoors and never in a closed space. Keep your grill away from buildings and check for damage before use.
Speed
If you need to put out a charcoal grill fast, water dousing is the quickest method. The coals cool down in just a few minutes. Suffocation takes much longer—sometimes up to 48 hours for the coals to cool completely. Natural burn-out is the slowest. The coals can stay hot for several hours.
Convenience
Suffocation and natural burn-out are both easy. You just close the lid and vents or leave the grill open and wait. Water dousing takes more effort. You need a bucket of water and must handle the hot grill carefully. Steam and splattering embers can make this method messy and dangerous.
Grill Longevity
If you want your grill to last, suffocation is the best choice. Water dousing can damage your grill. The sudden change in temperature can crack the metal or cause rust. Letting the grill cool slowly helps prevent damage. Regular cleaning and drying also help your grill last longer. Grills made from stainless steel or with rust-proof coatings last the longest. If you neglect cleaning or let moisture build up, rust can form and weaken your grill.
Tip:
Always dry your grill after use and store it with a good cover. This helps prevent rust and keeps your grill working for years.
Which Methods Preserve Charcoal and Which Are Fastest?
If you want to save leftover charcoal for next time, use the suffocation method. This method keeps unused charcoal dry and ready to use again. Water dousing and natural burn-out waste charcoal because the coals either get soaked or burn up completely. If you need to extinguish charcoal quickly, water dousing is the fastest, but it is not the best for your grill or for saving charcoal.
Suffocation Method

Instructions
You can use the suffocation method to put out your charcoal grill safely. This method works by closing the lid and all the vents to cut off oxygen access. Without oxygen, the fire cannot keep burning. Here are the steps you should follow:
Put on heat-resistant gloves to protect your hands.
Close the grill lid tightly.
Shut all the air vents on the grill.
Wait for the coals to cool down completely. This can take up to 48 hours.
Check that the coals are cold before you handle or dispose of them.
Tip: Never open the lid too soon. Hot coals can still burn you even after several hours.
Pros and Cons
Pros | Cons |
|---|---|
Safest method for you and your grill | Takes a long time (up to 48 hours) |
Preserves leftover charcoal | You must wait before cleaning |
No risk of steam or splattering | Not ideal if you need to move grill |
Protects grill from sudden damage |
Safety Tips
Always use gloves when you close the vents and lid. Keep children and pets away from the grill while it cools. Do not store the grill indoors until you know the coals are cold. If you need to check the coals, use a metal tool and touch them gently.
Note: Even if the grill looks cool, the coals inside can stay hot for a long time.
When to Use
Choose the suffocation method when you want to save leftover charcoal for your next cookout. This method works best if you have time to let the grill cool slowly. Use it when you want to protect your grill and avoid damage from water or sudden temperature changes.
Put Out a Charcoal Grill Fire: Water Dousing

Instructions
If you need to put out a charcoal grill fire quickly, you might think about using water. This method cools the coals fast, but you must follow the steps carefully to stay safe.
Put on heat-resistant gloves and use long tongs.
Remove the cooking grate to expose the hot coals.
Fill a metal bucket or large container with water.
Slowly pour water over the coals. Pour a little at a time to avoid splashing.
Stir the coals with a metal tool as you pour. This helps cool all the coals evenly.
Wait until you see no more steam or smoke.
Check that the coals are completely cool before you touch or throw them away.
Tip: Always stand back when you pour water. Hot steam can rise quickly and burn your skin.
Pros and Cons
Pros | Cons |
|---|---|
Fastest way to cool coals | Creates a lot of steam |
Can put out a charcoal grill fire in minutes | Hot embers may splatter |
Simple tools needed | Can damage your grill |
Wastes leftover charcoal |
Safety Tips
You must stay alert when you douse them in water. Steam can cause burns. Hot embers may jump out of the grill. Always use gloves and keep your face away from the grill. Never use this method indoors or near children and pets.
Warning: Sudden temperature changes can crack your grill or cause rust. Only use this method if you need to put out a charcoal grill fire fast.
When to Avoid
Avoid using water dousing if you want to save charcoal for next time. This method soaks the coals, so you cannot reuse them. Do not use water dousing if you care about your grill’s lifespan. Water can damage the metal and cause rust. Choose another method if you have time to let the grill cool slowly.
Natural Burn-Out
Instructions
You can let your charcoal grill cool down naturally by using the natural burn-out method. This method means you leave the lid open and allow the coals to burn out on their own. The fire will use up all the fuel and oxygen until the coals turn to ash. You do not need to add water or close the vents. You only need to wait. This process can take several hours, sometimes even overnight. Always check that the coals are completely cold before you clean or move the grill.
Tip: If you want to speed up the process a little, spread the coals out with a metal tool. This helps them burn out faster.
Pros and Cons
Pros | Cons |
|---|---|
Very simple and hands-off | Slowest method (can take hours) |
No risk of steam or splattering | Wastes leftover charcoal |
No sudden temperature changes | Leaves hot coals exposed |
No special tools needed | Not safe if children or pets nearby |
You do not need to do much with this method. You just wait. However, you cannot reuse the charcoal, and you must keep the grill in a safe place while it cools.
Safety Tips
You must follow safety steps when you let coals burn out naturally. Many grill fires start because people leave grills unattended or too close to flammable objects. Here are important tips:
Clean your grill before and after use to prevent grease fires.
Dispose of ashes in a metal container and douse them with water to make sure they are out.
Keep a fire extinguisher, hose, or bucket of sand nearby in case of emergency.
Place your grill away from buildings and anything that can catch fire.
Only use recommended fluids for lighting charcoal. Never add lighter fluid to hot coals.
Annual fire reports show that most grill fires happen because of poor cleaning, leaving grills alone, or placing them near flammable items.
Best Scenarios
Choose the natural burn-out method when you have plenty of time and do not need to save leftover charcoal. This method works well if you finish grilling early in the day and can watch the grill until the coals cool. Use it when you want a simple, hands-off way to let your grill cool down. Avoid this method if you need to move your grill soon or if children and pets play nearby.
Put Out a Charcoal Grill: Best Practices
Handling Hot Coals
When you put out a charcoal grill, you must handle hot coals with care. Always use heat-resistant gloves and long-handled tools. Never try to safely remove coals with your bare hands. After grilling, let the coals cool as much as possible. If you need to speed up the process, soak hot charcoal coals in water to fully extinguish them before you dispose of charcoal. Place the cooled coals in a metal container. This step prevents fire hazards and follows safety guidelines from the National Fire Protection Association (NFPA).
Tip: Never wrap hot coals in paper or plastic. Only use metal containers for disposal.
Ash Disposal
Proper ash disposal keeps you and your home safe. Once the coals are cold, scoop the ashes into a metal bucket. Store the bucket away from buildings and flammable items. Always double-check that no hot embers remain. If you want to reuse leftover charcoal, cover the grill tightly and close the vents to suffocate the coals. This method lets you put out a charcoal grill and save fuel for next time.
Preventing Flare-Ups
Flare-ups can happen fast, but you can prevent them with good habits:
Clean the grill after each use, especially the grates and grease traps.
Trim excess fat from meats to reduce drippings.
Never leave the grill unattended.
Keep a spray bottle of water and a fire extinguisher nearby.
Move food to cooler spots if flames rise.
Note: Never use water to put out grease fires. Close the lid and vents to cut off oxygen instead.
Grill Maintenance
Regular maintenance helps your grill last longer and keeps you safe. Clean grease and fat from the grill after every use. Check for gas leaks if you use a gas grill. Always grill outdoors and keep the grill at least 10 feet from buildings or trees. Use long-handled tools and flame-resistant mitts to avoid burns. Let the grill cool completely before moving or storing it.
You now know the safest ways to put out a charcoal grill. Always choose the method that fits your needs and keeps you safe. Remember, you protect your grill and yourself when you use the right steps to put out a charcoal grill. Follow best practices for handling coals, disposing of ash, and cleaning your grill. Safe grilling helps you enjoy every cookout.
