Say Goodbye to Heat Stains on Your Stainless Steel Grill


Stainless steel grills are a popular choice for outdoor cooking due to their durability, strength, and sleek appearance. However, over time, these grills develop heat stains, rust, and corrosion if not maintained properly. Heat stains are unsightly and affect the overall appearance of your grill. Luckily, heat stains are easy to remove with a few tips. This article will provide insight into why heat stains happen on stainless steel grills and the best ways to remove them.

Understanding Stainless Steel

Stainless steel is made from a combination of iron, carbon, and other elements such as chromium and nickel. Chromium makes up at least 10.5 percent of stainless steel and provides its resistance to corrosion and tarnishing. The higher the percentage of chromium in stainless steel, the more resistant it is to corrosion.

There are different types of stainless steel that vary in composition and therefore have varying degrees of resistance to corrosion. The most common types of stainless steel used in grills include 304, which contains 18 percent chromium and eight percent nickel, and 316L, which contains 16-18 percent chromium, 10-14 percent nickel, and two-three percent molybdenum.

Factors that contribute to the corrosion resistance of these materials include temperature, pH levels (acidity or alkalinity), humidity levels, salt concentration (in coastal environments), chemicals exposure (such as cleaning agents), occlusions (where water can’t move freely), exposure to heat or open flames for extended periods of time.

Causes of Heat Stains on Stainless Steel Grills

Heat stains happen when high-temperature exposures compromise the surface protective layer on the metal components of the grill. Grease buildup also contributes to discoloration on the grates and inside the grill’s walls. Over time, the accumulation of food debris, bacteria, and dirt on your grill can change its color and make it look dull. Improper cleaning techniques such as using abrasives can also cause damage to your grill.
