Outdoor Grill Maintenance with PGS Legacy Grills

So, you've purchased a PGS Legacy Series grill and you just wrapped up a great summer where you grilled for friends and family. You understand you must maintain your grill so it remains at optimal performance, but you're unsure how. Luckily for you, we've designed all of our outdoor gas grills for longevity and ease of maintenance. Of course, the only way to recreate those memories in the future is to have a fully functioning grill. While our Legacy grills have a long lifespan, they can be shortened if you fail to properly clean and maintain them regularly.

If you forget to maintain your grill, your burners can get clogged, and gunk can build up and damage the interior of the grill. Rust can completely change the appearance of your beautiful grill if you let it. Luckily, we're here to help!

Maintaining Your Gas Grill

Keeping your grill in tip-top shape isn't difficult, but you will need to take the time to maintain it. 

The expert consensus seems to be deep cleaning your grill once or twice per year. We recommend maintenance cleaning every few months. Occasionally, marinades may splatter or vegetables may fall through grates. It's guaranteed that grease will build up. Simply looking over your grill can give you an idea of what maintenance needs to be done. While you can choose to clean your grill anytime of the year, it is highly recommended to do one cleaning right before the summer months. 

Grease Tray

For our Legacy grills, before use, we suggest you line your grease tray with heavy-duty aluminum foil. Periodic inspection and the cleaning out of the grease tray is good practice for the long term health of your grill. The aluminum foil should be replaced every five to ten grill sessions depending upon the fatty meats you cook. If your grill has been left out in the rain without covering, remember to check your grease tray. Water is known to accumulate within it.

Regular replacement of aluminum foil will increase the longevity of your grease tray and keep your grill running smoothly. Remember, the aluminum foil should be cool before replacement.


Removing and replacing the burners allows for an easy and thorough cleaning of your Legacy grill. Before you begin cleaning the burners, be sure that your gas supply is off and that your feedline is devoid of any gas. Take your time and do not rush this process. To remove your burner assembly, first, remove the cooking grids and rock grates. Then, gently pull up on the back of the burner assembly.

Carefully cover the valve openings to keep out dirt. Using a stiff wire brush, brush both sides and the bottom of the inside of the burner. For any clogged flame holes, use a thin wire brush to open. A small bottle brush or long flexible wire can be used to clean out the venturis on the grill.

Cooking Grids

Routine maintenance of cooking grids is fairly straightforward. Cleaning your Legacy grill grids is best done by scrubbing the grids with a brass or stainless steel brush before and after cooking, while your grill is hot. Protect your hand from the heat by using a barbecue mitt while you clean out the cooking grids. If you notice a significant buildup of gunk, you may remove the grids from the grill and scrub them with a soap solution.

Remember to rinse thoroughly, and dry completely before reinstalling the cooking grids back onto your grill.  

Stainless Steel Maintenance

Our stainless steel Legacy grills are produced in California and are the perfect addition to any outdoor setting. Stainless steel grills are built with improved durability and are able to resist corrosion. Because of its strengths, stainless steel is often taken for granted and many assume it doesn't need the same care as other grills.

However, some care is required to make certain that your stainless steel grill can live up to this reputation, in both value and longevity.

Neglect of the general maintenance of your stainless steel grill can lead to the deterioration of its surface and, in some extreme cases, corrosion of the steel itself.

The most common culprits of corrosion on your stainless steel grill will be rust marks and pitting on the grill surface.

Rust Marks: More often than not when you see rust marks on your stainless steel grill, you are looking at the left behind particles from "normal" steel which has attached to your grill's surface. A common culprit is "wire-wool" scouring pads, but you may also see left over residue from carbon steel utensils. You can remove these marks by using a soft, damp cloth and a stainless cleaner. Removal of any rust marks should be done as soon as they are visible. This will avoid any staining on your grill. 

Pitting: Bleaches and certain foodstuffs are usually the reason for pitting on the surface of your grill. Some bleach concentrations will attack the stainless steel, damaging the surface. This can be avoided by using bleaches that are approved for stainless steel use and by completely rinsing away any remaining bleach with clean water after use. Foodstuffs are generally a non-issue for stainless steel grills, but occasionally, such as in the case of concentrated salt and vinegar mixtures, damage can be done to the stainless steel surface if left on for an extended amount of time. Make sure to wipe up your grill thoroughly during and after cooking to avoid damage. 

Daily Care in a Nutshell

To maintain the original appearance of your Legacy grill, we recommend following the below guidelines:

  1. After use, especially after grilling fatty meats, wipe your grill with a soft, damp cloth and rinse with warm/hot clean water. This helps to remove any excess substances that were created during the grilling process.
  2. Avoid using serious abrasives and scouring materials when you are cleaning your grill's stainless steel surfaces. These types of cleaners can leave marks on the surface and damage your grill's appearance. Be very careful with the tools you use on the stainless steel.
  3. Your PGS Grill has a directional polished grain. When cleaning, wash along this grain and not across it
  4. When drying the grill use soft, dry cloth or towels.
  5. Don't forget to check for propane leaks. You may check for propane leaks by running soapy water along the gas line and connections (with the propane turned on). If bubbles form, there is a leak, and you either need to tighten the connection or replace the line.
  6. Cover your grill. Keep your grill covered when not in use. Protecting your Legacy grill from the elements stops it from rusting or becoming dirty. 

The Bottom Line

Clean it regularly. Beyond the detailed cleaning above, wipe your grill off after each use.
