Array Oven and Grill Cleaner vs Heavy-Duty Degreaser: Which Should a Kitchen Use?
What each Array chemical is for, what the safety data sheets say, how to use them on ovens, grills and hoods, and which one to keep at each station.
Quick Answer
Use Array Oven and Grill Cleaner for baked-on carbon on ovens, grills and fryers. Use Array Heavy Duty Degreaser for daily grease on hoods, walls, floors and equipment outsides. The oven cleaner is far stronger and needs goggles and gloves, while the ready-to-use degreaser is a milder, lower-pH cleaner.
At a Glance
Key Takeaways
Two jobs, two chemicals
The oven and grill cleaner is for carbon and baked-on soil. The heavy duty degreaser is for fresh, everyday grease.
pH tells the story
Array's SDS puts its concentrated oven and grill cleaner above pH 13. The ready-to-use degreaser is pH 9.5.
PPE for the strong one
The oven and grill cleaner SDS calls for splash goggles and chemical-resistant gloves. It can burn skin and damage eyes.
Never on aluminum
High-alkaline oven cleaners attack aluminum. Use them only on surfaces the label allows.
Methodology
How we put this guide together
Difference
What is the difference between oven and grill cleaner and degreaser?
An oven and grill cleaner is a high-alkaline, often caustic, chemical for carbonized grease and burnt-on food. A heavy duty degreaser is a milder, everyday cleaner for fresh grease on hoods, walls, floors and equipment. The oven cleaner cuts harder soil, but it also carries far more risk for skin, eyes and surfaces.
Our Array Oven and Grill Cleaner comes in 3.78 L jugs, 2 per case, and our listing describes it as a high-alkaline liquid. The Array Heavy Duty Degreaser is ready to use in 946 mL bottles, 6 per case. For a wider look at degreasers, see our heavy-duty degreaser guide.
Field tip: Keep the oven cleaner at the line for closing. Keep the degreaser in the daily caddy.
SDS
What do the Array safety data sheets say?
Array's SDS for its concentrated oven and grill cleaner lists 6 percent sodium hydroxide, a Danger signal word and a pH above 13. It causes severe skin burns and serious eye damage and may corrode metals. The SDS for the ready-to-use heavy duty degreaser lists a Warning for eye irritation only, and a pH of 9.5.
Read the oven and grill cleaner SDS and the heavy duty degreaser SDS before staff use either product. Both say to mix only with water and never with other chemicals. Match the SDS to the code on the jug you receive, since formulas and labels can differ by market.
Field tip: Print both SDS pages and keep them in the WHMIS binder by the chemical shelf.
Ovens and grills
How do you use Array oven and grill cleaner?
Scrape off heavy debris first. Our listing and Array's product directions say to warm the oven or grill to 150 to 180 degrees Fahrenheit before you apply the cleaner. Apply it, work it with a non-abrasive pad, then rinse. Array's directions finish with a mild acid rinse and a water rinse.
Wear chemical-splash goggles and nitrile, neoprene or rubber gloves, as the SDS requires. Keep it off aluminum, painted and coated surfaces. After a grill is clean and rinsed, season it with a light coat of cooking oil. Use a grill brick for daily flat-top care between deep cleans.
Field tip: Read the jug label for whether to use it straight or diluted. Don't guess a ratio.
Daily grease
How do you use heavy duty degreaser?
Spray the Array Heavy Duty Degreaser straight from the bottle onto the greasy surface, let it sit briefly, then wipe and rinse. It's ready to use, so there's nothing to dilute. Our listing suggests letting it sit 2 to 3 minutes on hood filters before you wipe.
It's the better pick for hood exteriors, backsplashes, walls, carts and equipment outsides, where a caustic oven cleaner is overkill. For floors and general washable surfaces, use Array General Purpose Cleaner instead. Our dilution guide covers how to mix concentrates.
Field tip: Rinse food-contact surfaces with clean water after degreasing, then sanitize before food goes back on them.
Choosing
Which Array cleaner should a kitchen buy?
Most kitchens need both. Buy the oven and grill cleaner for weekly or closing deep cleans of ovens, grills and fryer exteriors with baked-on carbon. Buy the heavy duty degreaser for daily grease anywhere else. Using the strong chemical for daily jobs wastes product and exposes staff to more risk.
Order by how often each job happens in your kitchen. Store both in their original containers, below and away from food. The oven and grill cleaner SDS says to keep it away from acids, and the degreaser SDS says to protect it from freezing.
Field tip: Keep chemicals in the containers they came in. Never pour a cleaner into an unlabelled bottle or food tub.

|---|---|---|---|---|---|
| Array Oven and Grill Cleaner, bulk | 6010855635610 | Liquid, high-alkaline | 2 x 3.78 L | Danger, above pH 13 (concentrated version SDS) | Baked-on carbon on ovens and grills |

SDS details come from the Array safety data sheets linked below. The Array ready-to-use oven and grill spray was out of stock on November 13, 2026, so the Suma D9 spray is listed as the in-stock spray option.
Our Take
Why pH is the fastest way to choose
Most cleaner comparisons argue about brand. The quicker test is pH and signal word on the SDS. Above pH 13 with a Danger label means goggles, gloves, warm surfaces and no aluminum. A pH 9.5 Warning label means a daily cleaner your whole crew can use. Pick by the soil, then check the SDS before you buy.

FAQ
Frequently asked questions
Is oven cleaner the same as degreaser?
No. Oven cleaner is a strong, high-alkaline chemical for carbonized, baked-on soil. Degreaser is milder and made for fresh grease on hoods, walls and equipment. Array's SDS puts its concentrated oven and grill cleaner above pH 13 and its ready-to-use heavy duty degreaser at pH 9.5.
Is oven cleaner and grill cleaner the same?
Often, yes. Most commercial oven cleaners are labelled for ovens and grills because both build up the same carbonized grease. Array sells one product for both, the Array Oven and Grill Cleaner. Check the label for which surfaces are allowed, since aluminum and coated surfaces are usually excluded.
Can you use oven cleaner on aluminum?
No. High-alkaline oven cleaners attack aluminum and leave it dull, pitted or grey. Array's directions say not to use its oven and grill cleaner on aluminum. For aluminum equipment, use a milder cleaner like the Array Heavy Duty Degreaser, and check the equipment manual first.
Is heavy duty degreaser food safe?
Not to eat, and not as a final step on food-contact surfaces. Array's ready-to-use degreaser SDS lists eye irritation and says not to swallow it. After degreasing a prep surface, rinse with clean water and sanitize before food goes back on it. Keep it in its original labelled bottle.
Where can I find the Array oven and grill cleaner SDS?
Array publishes SDS sheets for its oven and grill cleaners. The concentrated oven and grill cleaner SDS and the ready-to-use grill and oven cleaner SDS are public. Match the SDS to the code on your jug, and call us at 1-833-462-8550 if you need the sheet for your delivery.
How do you use oven and grill cleaner?
Scrape off loose debris and warm the oven or grill to 150 to 180 degrees Fahrenheit. Apply the cleaner, scrub with a non-abrasive pad, then rinse. Array finishes with a mild acid rinse and a water rinse. Wear splash goggles and chemical gloves, as the SDS requires.
Is it safe to use the oven after cleaning?
Yes, once every trace of cleaner is rinsed off. Wipe the cavity with clean water until no residue or slippery film is left, and finish with any rinse step on the label. Re-oil a grill surface before cooking. Leftover alkaline residue can burn skin and taint food.
How do you use heavy duty degreaser?
Spray the ready-to-use degreaser straight onto the greasy surface, let it sit briefly, wipe, then rinse with clean water. Don't mix it with other chemicals. Array's SDS says mix only with water. For heavy carbon on ovens and grills, switch to the oven and grill cleaner.
How do you clean a flat top grill in a restaurant?
Scrape the flat top during service, then use a grill brick and a little oil while it's still warm at closing. Save the oven and grill cleaner for deep cleans of built-up carbon on steel surfaces the label allows. Rinse well and season the surface with oil afterward.
Do you sell Array Heavy Duty Grease Release?
We don't list it right now. For daily grease, we stock the Array Heavy Duty Degreaser in 946 mL bottles. For baked-on carbon, we stock the Array Oven and Grill Cleaner in 3.78 L jugs. Browse Cleaners & Degreasers for other brands.
How do you calculate shipping on bulk orders?
