A concentrated degreaser with restaurant-grade approval that dissolves oil without corrosive solvents.

Oil Eater is ultra concentrated, dissolving grease, oil, and dirt from any washable surface — floors, walls, driveways, grills, boats, and tools included. It carries USDA approval for food service facilities (A1, A4, A8), so it pairs serious degreasing with a biodegradable, noncorrosive formula.

Garage owners mention a year of use removing oil drips from the floor, cleaning cooling tins down to paintable metal, and even doubling as a hand cleaner. The honest catch: it fails on old, set-in concrete stains, so results vary by how long the stain has been there.

Customers note the same for engines: “Works great. Be careful because it will remove factory paint!” That strength cuts both ways — an occasional owner found it left white spots on blacktop or asphalt, so aim it at washable hard surfaces, not sealed driveways. At 2 pounds for two bottles, it’s noticeably lighter to lift than the 6.19-pound La’s combo above.

A full-concentrate foam that soaks into stains so deep they lift without much scrubbing.

Super Clean comes as a 32 oz foaming spray in full-concentrate form, so you can dilute it for everyday messes and stretch the bottle further. The foam clings to vertical surfaces — think greasy walls and stove backsplashes — while the concentrate dissolves buildup underneath.

The cleaning performance is the thing everyone raves about, with paint-beating results that sound like a magic trick: a set-in paint stain on jeans, washed and dried many times, vanished after a ten-minute soak and a brush. Owners also report tough yellow shower stains returning to white and greasy kitchen grime lifting fast.

Buyers sum it up as a “powerhouse” that’s earned status as the go-to cleaner in more than one household. The trade-off is value at full strength — the most enthusiastic owners wish they could afford to use it more liberally, which is exactly why the dilute-it-yourself option helps the bottle last.

Heavy-duty degreasing for the kitchen and garage that doesn’t leave you smelling like a gas pump.

This spray is formulated to dismantle grease, tar, paint, caulk, and even epoxies, making it a genuine all-rounder for home and auto. Strengths like this usually come with solvent stink, but the citrus scent keeps things pleasant — a big deal to owners who’ve been through mineral-spirit smells.

The cleaning performance is what owners talk about most, including a motorcycle engine case where gasoline-fire carbon smut wiped off cleanly. It also handles greasy stovetops after cooking and won’t leave your hands reeking, which makes it a solid pick for wall touch-ups and grime around range hoods.

The honest split: some owners call it heavy-duty while others find it not heavy-duty enough for the greasiest areas, and a few note mixed results on tub-level buildup. It’s formulated with non-toxic ingredients, so it fits households that want power without harsh chemicals.

The aerosol foam that clings to walls, sprays upside down, and cleans without scratching.

Simple Green’s foam formula clings to walls and cabinets instead of dripping, so you can clean vertical surfaces without a mess. The can sprays upside down, letting you reach the underside of range hoods and ceiling corners, and it’s non-abrasive, so it won’t scratch painted or delicate finishes.

Owners love it for intricate, detailed cleaning jobs, with one reporting it cleaned two RV air conditioners with a single can. It’s also a favorite for seniors or anyone with limited mobility because it’s low-effort — spray, let it sit, wipe.

The scent divides buyers: some find it light and fresh, others don’t, so test it in a small area first if you’re sensitive to fragrances. It works on counters, carpets, floors, fabric, equipment, and vehicles, making it among the most versatile wall-adjacent cleaners here.

A ready-to-use gallon that makes baked-on kitchen splatter wipe away with zero scrubbing.

Spitfire is a 1-gallon, ready-to-use formula — no mixing, no diluting, just spray and wipe for routine maintenance or heavy-duty cleanup. It’s built for walls, floors, countertops, equipment, appliances, and concrete, and it leaves a fresh pine scent behind.

Commercial kitchen owners swear by it, reporting that heavy grease and baked-in splatter lifts after a 15-minute dwell time with no scrubbing at all. The 8.47-pound gallon is a lot of bottle, but it replaces a cabinet full of weaker sprays.

The trade-off: owners warn the scent is strong enough that you’ll want ventilation while you work. One put it plainly — “it smells so use in vented area” — but the same owner came back to say the results are worth it.

Professional-strength Dawn concentrate that turns one gallon into 36 spray bottles.

Dawn PRO delivers the grease-fighting power of the brand you already trust, in a commercial concentrate designed for range hoods, stainless steel, fryers, stoves, and ovens. One gallon yields 36 spray bottles of 32 oz each, so two gallons cover a year of kitchen degreasing.

Reviewers point out it cuts grease on painted walls, tile, and stainless steel without residue or streaks, and the concentrate dilutes easily with no harsh chemical odor. It outperforms other cleaners on high-traffic grease — exactly what you want above a stove.

The honest limit: it melts greasy, oily film beautifully but won’t budge hard, shiny baked-on oven splatters. The 18.07-pound case of two gallons is the heaviest item here, so budget for the storage space before you buy.

A pro-strength citrus concentrate that wipes out kitchen grease and smells good doing it.

Zep’s concentrated formula uses a natural citrus solvent to dissolve grease on appliances, grills, stovetops, concrete, tools, engines, and stainless steel. The cleaning company owners are the most vocal fans — one runs a business and says they “couldn’t survive” without this product on kitchens covered in grease.

The manufacturer’s own guidance draws a clear line: use it on hard surfaces, but skip glass, acrylic, auto paint, leather, and natural stone. That makes it a strong wall degreaser for painted drywall and tile, but not a grab-anywhere spray.

Shoppers say it works well on vinyl fake hardwood without residue, cleans the outside of trailers, and smells pleasantly clean while it works. Give it extra time on thick cooking grease around ovens — the maker’s tip is to let it sit longer where buildup is heaviest.

The foam-free concentrate that made a decade of cigarette smoke disappear from walls with no scrubbing.

Unsmoke Wall Wash is built for the toughest wall job there is: removing grease, soot, tar, and nicotine residue left by fires or years of smoking. It’s a concentrated formula you dilute and apply with pre-saturated towels, a foaming device, or a sprayer, and it doubles as an odor eliminator.

Effectiveness is the most-discussed trait here, and the stories stand out — one owner watched smoke tar “disappear before your very eyes” on an RV interior, another removed a decade of cigarette smoke from ceilings with minimal effort, and a third cleared soot-covered walls to pristine after fireplace use.

Owners specifically praise that it needs no scrubbing and isn’t heavily scented, and it’s a great first step in wall prep before painting. It works better on cooking smoke and oil stains than on some cigarette residue, and the scent itself gets mixed feedback from the most sensitive noses.
