This regimen serves to effectively eliminate any stubborn burn-on grease that may have accumulated on the surface of the burner, thus facilitating ease of use in subsequent cooking operations.

Cleaning Rust Iron Grill Grates

Cast iron grill grates are always coated with porcelain to help prevent rusting. Porcelain built-in of an inorganic compound comprising metals and non-metals. It is made by heating a clay mineral known as kaolin.  Porcelain is tough and durable; it can withstand heat at high temperatures. This property makes it suitable for coating cooking surfaces as it does not melt.

Cleaning Rust Iron Grill Grates

The prevalence of porcelain coating on cast iron grill grates serves to effectively prevent the onset of rusting. Porcelain, a highly resilient and durable inorganic compound, is composed of a combination of metals and non-metals, and is generated by subjecting the clay mineral known as kaolin to intense heat. Its inherent robustness enables it to endure high temperatures without succumbing to melting, rendering it a highly desirable coating material for cooking surfaces.

Iron grill grates, when coated with porcelain, become significantly easier to maintain, as they exhibit heightened resistance to rusting upon contact with water. However, with frequent use and cleaning, the porcelain coating may gradually wear off, leaving the cast iron vulnerable to moisture and hence more susceptible to rusting. To prevent the ruinous effects of foul-smelling rust on the flavor of cooked food, various methods for cleaning rusty iron grills exist.


Wire brush: This is a brush made of wire bristles.  The wire can be made from brass or steel. The hard wire bristles act as perfect abrasive equipment for scraping off from cast iron grills.

Rust remover: There are chemical solutions if applied on rust, reacting to form a barrier. Rust removers for cleaning cast iron grills are relatively cheap in the market. Evapo- Rust is one of the most common rust removers for domestic use.

Apply rust remover on the iron grill grates and leave it for 3 minutes.  Thoroughly brush the iron grates using the wire brush until the cast iron becomes visible.  Rinse the grates and season for storage.

Cleaning iron grill grates using Homemade Rust Removers

For those seeking an alternative to commercial rust removers, a homemade solution can be easily concocted using common household ingredients. The concoction is effortlessly prepared if the requisite components are readily available. A cleaning paste can be fashioned by combining Borax and lemon juice, with Borax being a ubiquitous household product utilized for cleaning and water softening. Borax is essentially composed of boric acid and boron, and can be substituted with baking soda if unavailable.

To apply the cleaning paste, it should be spread evenly on the rust-infested iron grill grates, and allowed to rest for a duration of 30 minutes. The paste must be continually monitored during this period to ensure it does not dry out, and can be rejuvenated by spraying it with water. Thereafter, a nylon brush should be utilized to scrub the grill grates thoroughly. Finally, the grill grates should be rinsed and seasoned for subsequent use. The cleaning process can be repeated as deemed necessary, depending on the degree of rust residue present on the surface.

Another homemade rust remover can be effortlessly prepared by spraying baking soda on a sliced potato. The organic acids present in the potato contribute to the dissolution of rust residues, while the baking soda facilitates the scrubbing away of these particles. It should be noted, however, that this method is only suitable for mild rust infestations on considerably small cast iron grill grates. After cleaning, it is recommended that the grill be rinsed and left to dry before subsequent use.

Vinegar is also a common homemade rust remover.  Make sure you use undiluted vinegar for maximum performance.  For mild rust, spray vinegar on the rusted iron grills and leave it to soak for half an hour.  The time you spend soaking will depend on the amount of rust residue deposited on the weber grills.

You can also consider pouring undiluted vinegar in a basin and dipping rusted iron grills in the bath.  You could use this for smaller objects such as removable iron grill plates. Once rust has dissolved, use a nylon brush to scrub the surface of iron grills. Thoroughly rinse the iron grill grates and wipe with a clean cloth.

Safety Precautions while using rust removers

It is important to exercise caution when handling rust removers, as they typically rely on acids that dissolve rust and salts that act as abrasive agents. Homemade rust removers are generally less hazardous compared to their commercial counterparts, but care should still be taken to avoid self-injury.

Commercial rust removers can be especially hazardous, as they are corrosive to metals and can cause skin corrosion upon contact. To avoid such complications, it is essential to avoid skin contact with these chemicals, as they can cause severe skin burns that may necessitate medical attention.

In addition to skin corrosion, rust removers can also pose a significant threat to eye health. When using modern rust removers to remove heavy rust residues from cast iron grills, it is highly recommended to wear protective goggles. Homemade rust removers are typically less harmful, and the use of protective goggles is not mandatory. Nevertheless, one should still exercise caution to prevent exposing their eyes to hazardous chemicals while scrubbing off rust residues.

If accidentally inhaled, move to a place with fresh air and monitor yourself. If the symptoms persist, consider seeking medical help immediately. Ensure you inform medical personnel of the type of rust remover you used.

Keep the chemical in the original container, and make sure you read and understand the safety precautions labeled on the container.  The original container has a corrosive-resistant inner lining that helps protect it from damage.

In case of an accident, a rapid first aid response is necessary to avoid serious damage.  If the chemical comes into contact with the skin, make sure you rinse that part thoroughly with cold water. If accidentally swallowed, avoid inducing vomit and instead rinse your mouth thoroughly. Get medical attention if you feel too exposed to the chemical.

Disposal of the container and its contents should be done by regulations and safety precautions labeled on the chemical.

Final Verdict

Cast iron grills are essential equipment for a good grilling experience.  Even though steel grills are used for the same purpose, they cannot withstand heat at very high temperatures.  Iron is, therefore, the most suitable metal for manufacturing cooking grills. Standard cooking grills such as Weber products require constant maintenance.

Make sure you clean the grills made of cast iron immediately after use. Since bare cast iron is prone to rust, consider purchasing grills coated in porcelain to protect the surface from rust. That should also equip you with rust removers in the unlikely event the grills develop rust.
