How to Rustproof a Fire Pit

This blog post will answer the question, “How to Rustproof a Fire Pit?” and cover topics like how to keep fire pit from rusting and different ways of keeping a fire pit rust-free.  

How to Rustproof a Fire Pit?

A UV and/or waterproof cover should be used to protect the fire pit. If the fire pit will not be utilized for an extended length of time or you reside in a high-humidity environment like the seaside, apply a light coat of any ordinary cooking oil to any exposed metal. Check your fire pit a day before each use for any early signs of corrosion and correct them.

How to keep fire pit from Rusting:

The fire pit should be kept looking and running at its best through regular care and maintenance in order to have the finest fire pit experience. Maintenance varies depending on the type of fire pit and the materials used in its construction. 

Here are some actions you should always take to protect your fire pit from rusting, retain its original appearance, and guarantee it performs efficiently:

  • Do not leave it exposed to the weather outside.
  • Apply a rust-resistant high-temperature spray to your fire pit on a regular basis to keep it rust-free.
  • Make use of a fire pit cover.

I will now elaborate on the guidance given above to protect a fire pit from rusting.

Do not leave it exposed to the weather outside:

Direct exposure to the environment can harm fire pit badly unless your fire pit is made of natural stone or concrete.

Direct exposure can harm in the following ways:

  • Leaving it outside in the elements like rain, snow, and even direct sunlight is one of the quickest ways to cause it to rust and deteriorate. 
  • When exposed to moisture, most metal fire pits will start flowing immediately, while others, such as slate tabletop fire pits, may spot.

Don’t leave your fire pit to the mercy of nature’s elements if you don’t have to in the case of outdoor portable fire pits. If you must leave your outdoor fire pit outside, you must at the very least cover it with a roof or use a fire pit cover; otherwise, metal fire pits may crumble after only a few seasons of use.

Apply a rust-resistant high-temperature spray to your fire pit on a regular basis to keep it rust-free:

The protective weather-resistant and high-temperature paint on most outdoor metal fire pits are always present however, in other metal fire pits, this coating is thin and will most likely fade off after a few usages. 

Why you should use high-temperature sprays:

  • Even high-quality fire pit coatings wear off over time, which is why I recommend adding a second layer of weather-resistant high-temperature paint on your fire pit before you use it for the first time, and then on a frequent basis after that. 
  • This will ensure that your fire pit is double-protected the first time around, reducing the deterioration process and preventing rusting. 

Here are my two favorite picks for high-temperature rust-resistant fire pit sprays:

Features of Rust-Oleum High-Temperature Sprays:

  • Rust-Oleum has a unique design and a deep satin texture that dries quickly in 30 minutes. 
  • It has an excellent rust-preventative enamel coating and can endure temperatures up to 1200 degrees Fahrenheit. 
  • With this fire pit spray paint, no primer is required. Copper and black finishes are available.

Make use of a fire pit cover:

A fire pit cover is one of those must-have fire pit accessories that will ensure that your fire pit is protected from the weather. When left exposed to the weather, most furnishings, including outdoor furniture, will deteriorate, which is why protective outdoor coverings are used.

A fire pit cover is the most effective way to keep your fire pit from rusting and finally wearing away. Because of the broad variety of fire pit designs and sizes, fire pit covers are also available in a variety of sizes, shapes, and materials to fit most fire pit sizes and designs. 

Here are a few of the best fire pit covers I’ve found:

Porch Shield fire pit cover

Gas fire pit cover

Widenyard Square fire pit cover

The following are the top reasons to cover your firepit:

  • To avoid stray sparks from causing damage to neighboring goods, such as patio cushions.
  • To prevent rusting and damage to your firepit.
  •  To keep your firepit dry so you can start a fire easily in the future.

Buying Guide for the Best Fire Pit Covers:

One can keep a fire pit exposed to the elements with the use of fire pit covers, ensuring that it always looks wonderful. Furthermore, sheltering your pit from the elements helps guarantee that it remains in good working order.

 Investing in a high-quality cover for your pit is an investment you won’t regret, and these pointers will help you narrow down your options. The shapes, sizes, materials, and fittings are the only changes between these coverings. 

The next section will aid you in selecting the best fire pit cover.

What considerations should you think about while selecting a fire pit cover?

  • System of ventilation
  • Material
  • Measurement
  • Shape

System of ventilation:

The purpose of a fire pit cover is to protect your fire pit from the weather. The cover is also water-resistant on both sides, which is an important feature.

Why ventilation is compulsory: 

  • Even if your fire pit is waterproofed, it might still absorb moisture. Moisture might build up in your cover during wet weather. 
  • Furthermore, a cover that does not allow for ventilation might cause rust on your fire pit as well as other issues. As a result, look for a cover that has at least two vents.

Material:

Low-quality cover fabrics are distinguished from high-quality protection textiles and tarps by a number of features.

The two most important features are:

  • Waterproofing 
  • UV resistance.

Best fabric for fire pit cover:

Polyester with a PVC backing is always a smart choice. 

Benefits of using Polyester:

  • Polyester is a highly durable fabric that is both UV and water-resistant, and it outperforms cotton and canvas in inclement weather. 
  • You should never skimp on the quality of a fire pit cover since it will impair the pit’s integrity.

Measurement:

You must measure from an even surface before starting the fire. You need to measure height, width, and length for square or rectangle-shaped pits. 

Steps for measurement:

  • You’ll need to collect both height and diameter if your pit is round or bowl-shaped. 
  • The height of the bowl can be measured using a standard measuring tape. 
  • The bowl’s top edge will be parallel to the ground in this case. 
  • Next, measure the diameter of the bowl. It traces a straight line across the pit’s middle. 

If your fire pit is formed like an octagon or hexagon, you’ll need to add measurements for each angle of the unusual design.

Ventilation:

The purpose of a fire pit cover is to protect your fire pit from the weather.

Why ventilation is necessary:

  • An important feature is that a cove must be water-resistant on both sides. 
  • Even if your fire pit is waterproofed, it might still absorb moisture. Moisture might build up in your cover during wet weather. 
  • Furthermore, a cover that does not allow for ventilation might cause rust on your fire pit as well as other issues. As a result, look for a cover that has at least two vents.

Different ways to keep your fire pit rust-free:

  • Keeping Your Fire Pit Clean.
  • Avoid Using a Lighter Fluid.
  • Allow the fire to go out naturally.
  • Keep an eye on what you burn.

I will now elaborate on the points given above.

Keeping Your Fire Pit Clean:

It’s not difficult to clean out the fire pit. Ashes can absorb moisture from the air or rain and keep it on the metal’s surface. To make matters worse, the fire pit’s inner surface receives the most heat and is hence the most vulnerable to rust.

Steps to clean fire pit:

  • You can dump the ash somewhere safe after ensuring that the fire pit is not producing any heat and that all the coals have been removed. 
  • Make sure the ash is completely dry before spraying or watering it down to ensure there is no risk of a second fire.
  • Scrub the inside of the fire pit with hot, soapy water and a soft cloth. 
  • Wipe the fire pit dry with a dry cloth after fully rinsing the soap and water. 
  • Water sitting in a metal fire pit can cause it to rust, so don’t let it sit after a rainstorm or cleaning.
Materials Needed
Soapy water
Soft cloth
Scrubber

Avoid Using a Lighter Fluid:

You should be able to light your fire pit with little more than small pieces of tinder and kindling if you use dry wood. However, you should not use lighter fluid to start it. 

Why you should not use Lighter Fluid:

  • Apart from the dangers of bodily harm and property damage, lighter fluid can also destroy the finish of your fire pit. 
  • After just one or two applications of lighter fluid, there’s unlikely to be any obvious damage. 
  • Nonetheless, it’s preferable to err on the side of caution and stay away from lighter fluid entirely.

Allow the fire to go out naturally:

Sure, dousing your fire pit with water makes it easier and faster to put out, but it also raises the chance of damage. Unless it’s an emergency and you need to put out the fire right away, you should wait for it to go out naturally. 

Why should you allow the fire to go out naturally:

  • When you saturate a still-burning fire pit with water, the temperature changes dramatically. 
  • The fire pit’s structural integrity may be weakened as the 1,000-degree fire is rapidly cooled.

Keep an eye on what you burn:

You should avoid burning rubbish or pressure-treated lumber in your fire pit. Choose natural, locally obtained wood that is dry and not moist instead. 

How burning trash and pressure-treated wood effects fire pit:

  • Burning trash and/or pressure-treated lumber can produce hazardous gases and chemicals, some of which can harm your fire pit over time (not to mention be unhealthy). 
  • Wet wood doesn’t burn as well as dry wood, so you might have trouble lighting it.

Frequently Asked Questions(FAQs): How To Rustproof A Fire Pit?

How do you preserve a fire pit?

A firepit can be preserved by the following guidance below:

  • Use only dry wood for fires. Even if it appears to be dry, your firewood most likely contains moisture.
  • Make Use of Larger Firewood Pieces.
  • Place the fire pit near a windbreak.
  • Before you use your fire pit, make sure it’s completely dry.
  • Allow your firewood to take a breath.

What is the easiest way to dig a fire pit?

Mark the center of the pit and measure outwards to a distance equal to half the overall diameter in every direction while digging an in-ground fire pit. Mark the perimeter of the grass and begin digging. Depending on how deep you want your fire foundation to be, excavate to a depth of six to twelve inches.

What oil do you use for fire pit?

Oil made from vegetables(Vegetable Oil).

Apply a thin coat of vegetable oil (canola, maize oil, etc.) to the exposed metal surfaces of your fire pit after clearing all debris from each burn and wiping down the inside of the bowl.

How can I make my fire pit last longer?

So, if you’re bored of lighting and relighting your fire pit all night, consider the following suggestions to keep it going.

Use only dry firewood.

  • Make Use of Larger Firewood Pieces.
  • Place the fire pit near a windbreak.
  • Before you use your fire pit, make sure it’s completely dry.
  • Allow your firewood to breathe.
  • Weather to be wary of…
  • Add more wood to the fire.

Does rain damage fire pit?

Propane fire pits designed for outdoor use can withstand contact with water without sustaining damage. Long durations of exposure to rain and water, on the other hand, might generate a buildup in the burner, which can damage it and leave it ineffective. Rusting is also a possibility.
