Your pellet grill cover takes more abuse than almost any other accessory in your outdoor kitchen. It faces sun, rain, grease, dust, and wind every day, and how you care for it determines whether it lasts one season or several.
This guide shows you how to maintain pellet grill cover materials the right way, from cleaning and drying to storing and protecting the waterproof finish. We focus on practical habits that work for the most common fabrics like 600D and 1000D Oxford, plus what to look for when you choose your next cover.

How to Choose the Right Care Approach for Your Cover
Not all pellet grill covers need the same maintenance. The fabric, coating, and construction determine how you should clean and store it. We have evaluated covers from brands like SunPatio, GuardKove, and Utheer to see how material differences affect long term care.
1. Know Your Fabric and Coating
Before you clean anything, check what your cover is made of. Most pellet grill covers use 600D or 1000D Oxford polyester, but the inner coating matters just as much. You will see PVC linings, vinyl linings, and PU coatings across different models.
For example, the SunPatio Outdoor Heavy Duty Waterproof Wood Pellet uses a polyester fabric with a waterproof vinyl lining and FadeStop treatment, while the Comnova Grill Cover for Pit Boss 820-850 uses a 600D Oxford with a PU coating that is softer and more breathable than PVC. The GuardKove and KINGLY options use a thicker 1000D Oxford with a PVC lining and sealed seam tape for extra water resistance. Thicker 1000D fabric resists tearing better, but PU coatings often need gentler cleaning to avoid stripping the finish.
2. Use a Gentle Cleaning Routine That Protects Waterproofing
You do not need harsh chemicals to keep a cover clean. In fact, strong detergents and pressure washers can break down waterproof coatings and seam tape. The best routine is simple and regular.
Start by shaking off loose debris and leaves, then rinse with a garden hose. For stuck on grease or pollen, use lukewarm water with a small amount of mild soap and a soft cloth or sponge, then rinse thoroughly. Both Utheer and SunPatio recommend hosing off and air drying in the sun, and KINGLY specifically notes its covers are not washer machine safe. Avoid machine washing, bleach, and stiff brushes, and always let the grill cool completely before you cover it again to prevent heat damage and trapped moisture. Pairing this habit with a clean cooking setup, like the gear in our best bbq tools set under $300, helps reduce grease buildup on the cover itself.
3. Dry Completely Before Storage to Prevent Mildew
Moisture is the fastest way to shorten a cover’s life. Even a cover labeled 100% waterproof can develop mildew or odor if you fold it while damp. After every wash or heavy rain, give it time to dry fully.
Hang the cover or drape it over the grill in the sun until both the outer fabric and inner lining are dry to the touch. Pay attention to seams and the bottom hem where water collects. If you need to store the cover during the peak grilling months, fold it loosely once dry and keep it in a dry, ventilated spot rather than a sealed plastic bin. Covers with handles, like the Utheer 73700 600D Grill Cover for Pit Boss, make hanging and air drying easier.
4. Maintain a Secure, Wind Resistant Fit
A loose cover flaps in the wind, and that constant movement causes abrasion, torn seams, and faded spots. A secure fit is not just about looks, it is a maintenance issue. Look for the fastening system your cover uses and adjust it every time you put it on.
Some models use adjustable drawstring straps at the bottom, like the Utheer and the Heavy Duty 600D Grill Cover Compatible with Z, while others use side buckle straps or velcro magic bands like the Comnova and Pit Boss Universal Pellet Grill Cover Large. GuardKove and KINGLY add side zippers so you can put the cover on without dragging it across the grease bucket or chimney. Tighten the straps just enough to keep the cover snug without stressing the seams, and check them after storms.
5. Protect Against Sun, Dust, and Seasonal Wear
UV exposure is what causes most fading and cracking over time. If your grill sits in direct sun all day, choose a cover with a confirmed UV resistant treatment and make a habit of rinsing off dust and pollen that can act like sandpaper on the coating.
Covers like the SunPatio with FadeStop, the GuardKove with UPF 50+ fabric, and the Comnova which has been assessed for UV aging are designed to resist fading for multiple seasons, but they still benefit from regular rinsing. In winter, brush off snow instead of letting it sit and melt repeatedly, and in windy seasons inspect the bottom edge and seams for early signs of wear.

It is perfect for owners of Traeger, Z Grills 700/600 series, Pit Boss Sportsman 820, Grilla Silverbac and Member's Mark models who need dependable outdoor coverage.
In real world use, the standout is the 1000D high density Oxford fabric that is twice as thick as ordinary grill cover material.

It is ideal for owners who keep their grill outdoors year round and want premium protection without the cost of a branded OEM cover.

The black color also retains heat in direct sun, and like most PVC-lined covers it benefits from periodic airing to avoid trapped condensation.

The black finish looks clean and the material is easy to handle when covering or removing the grill.
There are a few tradeoffs to consider. The cover is slightly thinner than the factory original, and the design may leave the very bottom of the legs and casters exposed on some models.

There are a few limitations to consider. Compatibility is specific and it does not fit the Z Grills 550A, so buyers must double check their model number before ordering. As a third party cover from ZBXFCSH rather than Z Grills OEM, the fit and finish may vary slightly from the original.

Common Mistakes to Avoid
One of the most common mistakes is covering a hot grill. Even if you are in a hurry, wait 10 to 15 minutes until the grill is completely cool. Trapped heat can soften PVC and vinyl linings, warp seam tape, and create condensation that leads to rust on the grill and mildew on the cover.
Another mistake is using a pressure washer or putting the cover in the washing machine. While it seems faster, high pressure and agitation can peel the waterproof coating and open up stitched seams. Stick to a garden hose, mild soap, and a soft cloth, then air dry. If your cover has a zipper, like the GuardKove or KINGLY models, keep the zipper clean and free of grit so it does not snag or separate.
Finally, do not ignore a poor fit. Buying a cover that is too large and leaving the straps loose lets wind get underneath and whip the fabric against the grill. That friction wears through the water resistant finish much faster than normal weather. Always measure length, width, and height, and use the adjustable straps, buckles, or velcro to create a snug fit every time.
Frequently Asked Questions
How often should I clean my pellet grill cover?
Rinse your cover with water every two to four weeks during grilling season, and do a deeper clean with mild soap every couple of months or when you notice grease, pollen, or bird droppings. More frequent light rinses prevent buildup that can stain or degrade the coating.
Can I use soap or cleaners on a waterproof grill cover?
Yes, but keep it gentle. Use lukewarm water and a small amount of mild dish soap with a soft cloth, then rinse completely. Avoid bleach, harsh degreasers, and abrasive pads that can strip the PU, PVC, or vinyl waterproof layer and damage seam tape.
How do I prevent my pellet grill cover from blowing away or getting moldy?
Secure the cover with its built in straps, buckles, or drawstrings and check the fit after windy days. To prevent mold, never fold or store the cover while damp, always air dry it fully in the sun and ensure the grill is cool and dry before covering.
