Best Degreasers of 2026

Engine bay, shower wall, garden tools: we handed this gallon the three greases that usually need three different bottles, and it took all of them. That range is why it's our top pick. Spray Nine is a cleaner, a degreaser, and a disinfectant in one ready-to-use liquid, so there's nothing to measure and no second jug to buy — you pour it into a trigger bottle and work. When we don't yet know what a mess is made of, this is the bottle that comes off the shelf first.

The disinfecting half is more useful than it sounds. The label gives wet-contact times — ten seconds to sanitize, thirty for viruses, forty-five for bacteria — which tells you it's meant to sit, not be sprayed and wiped in one motion. In a bathroom or around a sink, that one pass does both jobs. And at a gallon, the per-ounce math beats every trigger spray here, which is the quiet reason it ends up handling the ugly jobs the pretty bottles get saved for.

Where we're careful is strength. This is a professional-strength formula, and it can dull a soft plastic or lift a finish that isn't fully cured, so we test a hidden corner before taking it to anything rubbery or painted. That's the trade: real power on concrete, tile, and mildew-prone corners, and a bottle you don't hand to someone who scrubs without reading the label. For a garage-and-bathroom household, that trade is worth making.

The EPA's Safer Choice mark is the first thing to notice on this jug, and it's why the bottle lives in the house rather than the garage. The formula is phosphate-free and biodegradable, and it carries a low-odor claim that holds up — you can work in a small bathroom without propping the door open.

What earns it a place is control. It's a concentrate, so you set the strength: a weak mix for a spray bottle of everyday cleaner, something stronger for a greasy range hood, and a gallon that lasts months when you mix by the bottle. We used it on counters, a vinyl-sided wall, painted trim, and the housing of a shop machine, and it lifted the film without the sharp smell that comes with solvent formulas. It is a mild degreaser, though. Baked-on oven grease is not its job, and no amount of soaking turns it into a solvent.

Read the dilution as the value rather than the chore. It's listed for carpet and upholstery as well as hard surfaces, and for floor scrubbers, carpet extractors, foamers, and pressure washers, which is a wider brief than any trigger spray here can claim. If your grease is everyday cooking film, dust-bound oil, and soap scum, this handles it in one pass and leaves the room breathable.

Citrus solvent does two jobs soapy formulas can't: it cuts carbonized grease off a grill grate, and it dissolves the adhesive a sticker or a shelf liner leaves behind. This Zep concentrate is built around that solvent, and it's the one we keep for metal that has seen heat — grates, stovetops, tools, engine parts, fiberglass, aluminum, stainless, concrete.

A gallon goes a long way at concentrate strength, and the label is honest about dwell time: thick buildup around an oven or a cooking space needs longer before you wipe, and it works faster on a warm surface than a cold one. Our first pass on heavy carbon did less than our second, which is the pattern with any solvent — the first application softens, the second lifts. The orange smell is real citrus rather than chemical perfume, which matters when you're leaning over a hot engine.

Our verdict: buy it for greasy metal and grimy concrete, and read the back of the bottle before you take it anywhere else. It's the strongest solvent in this group and the one that handles char, road dirt, and adhesive in the same afternoon, and it costs less than the ready-to-use gallon we recommend as the default. A garage shelf with this and a mild concentrate on it covers almost everything.

It's the least expensive bottle in this roundup, and it's the one we keep on the kitchen counter because of what it won't do: no dulling on sealed granite or marble, no clouding on stainless, no trouble on glazed tile, acrylic, aluminum, brass, or bronze. Most degreasers make you check a list before you spray. This one names the good surfaces as approved.

It disinfects too, and the label claims 99.9% of bacteria and viruses when used as directed — which means leaving it visibly wet for the stated time instead of wiping it straight off. On a daily countertop pass that's the difference between cleaning and actually sanitizing, and it's rare in a bottle this cheap.

The limit is muscle. This is for the film that builds on a cooktop and the splatter beside it, not for carbon baked onto a grate for a year; for that, the citrus concentrate and a few minutes of patience do the work. For the everyday grease a kitchen throws at a counter in a week, this is the bottle we buy again, and the surface list is why we don't have to think about it.

One ounce per gallon — two tablespoons — is the mix, and the bottle holds 32 ounces, which works out to the 32 gallons the label promises. That arithmetic is the entire proposition: you're buying a bucket cleaner, not a spray bottle, and the measuring is the price of admission.

In a bucket it's a workhorse. The label covers cookware, grills, dishes, woodwork, countertops, broilers, equipment, and tools, and it says the formula works in hard water as well as soft, which matters if you're filling a bucket from a well. A capful in a sink of hot water cuts the grease off a roasting pan without a second soak.

The use that earns it space outside the kitchen is laundry. A drop at full strength worked into a grease stain before the wash is the reason one of these ends up in a utility room, and a weekly dose down a slow kitchen drain is another job it handles. Neither is on the front of the bottle, and both are the sort of thing you only learn by keeping a jug around.

Our take: the measuring is the only real labor in it, and the rest is a jug that quietly replaces most of the shelf — dishes, floors, laundry, and the grill all come out of the same bottle. What it won't do is live beside the sponge. There's no trigger, no foam, and none of the instant gratification a spray gives you.

If there's a pressure washer in the garage, this is the jug that belongs beside it. The label names pressure washing, parts washing, ultrasonic cleaning, floors, walls, appliances, commercial kitchens and baths, and automotive or RV work — a brief about equipment and buildings rather than countertops.

We rate it the heavy-duty concentrate here for anyone diluting by the bucket. It's non-corrosive, listed for metal, plastic, and carpet, and unscented, which in a closed garage is worth more than a nice fragrance. Engine bays, porch floors, and shop equipment are the work it's built for, and it rinses without leaving a film behind.

The name promises a little more than the formula delivers on carbonized grease. A citrus solvent will outrun it on a grill grate or a decades-old oven, and the heavy-duty label sets an expectation a general-purpose concentrate can't meet. What it offers instead is volume and neutrality: no scent, no corrosion, and a dilution you set for the job in front of you. That's the one we want on a shelf where the work is big and repeated.

Painted cabinet fronts and door trim are where an all-purpose cleaner can quietly cost you a sheen, and they're the reason we keep this Zep gallon. The back label prints three dilutions — 3 fluid ounces per 32 ounces of water for light soil, 6 for medium, full strength for tough — and that chart is the difference between a cleaner that's safe on paint and one that isn't.

Diluted, it's a household workhorse: tile, stainless, porcelain, fiberglass, walls, and floors. At full strength it takes the grease film off the cabinet run above a range and the hood beside it. The label lists painted doors and trim by name, which is more specific guidance than most bottles of this kind bother with.

Pouring from a gallon into a 32-ounce spray bottle is clumsy without a funnel, and that's the only friction in the system. Once it's in the bottle, the chart does the thinking: 3 ounces per quart makes a wall-and-floor cleaner, full strength makes a degreaser. It's one of the lowest-priced gallons here, and the one we trust on painted surfaces.

Two jobs in one jug: this 409 refill dissolves oil-based soil and kills 99.9% of germs on hard, nonporous surfaces, without bleach in the formula. That combination is the appeal — one pass around a kitchen that gets greasy and germy in the same afternoon.

The germ claim is specific — Salmonella, Staph, E. coli, and athlete's foot fungus — and the label expects the surface to stay visibly wet for the stated contact time, which is where most spray-and-wipe routines fall short. Countertops, stovetops, stainless appliances, and sinks are the intended targets.

It's sold for offices, day cares, schools, hotels, and restaurants, and that framing is accurate. This is a workhorse refill for someone cleaning a lot of hard surface, not a specialty solvent for a grill grate. A 128-ounce jug refills a trigger bottle four times over.

Our take: buy it for the combination, not for the muscle. It handles stovetop film, sink surrounds, and stainless without a bleach smell, and it does it at refill pricing. For carbonized grease a solvent concentrate is the right tool, and no amount of dwell time turns this into one.
