How the Five Compare on the Numbers
Three of the five publish a width, a depth and a height. Therapy lists 2.75 inches wide, 4 inches deep and 8.5 inches tall. Zep lists 2.5 inches wide, 2.5 inches deep and 10 inches tall. All-Clad lists 2.5 inches wide, 2.5 inches deep and 7 inches tall. Weiman and Sprayway publish none of the three, so for those two the maker states no dimensions at all.
Weight is published for all five. Weiman lists 0.13 pounds, Therapy 0.2 pounds, Sprayway 0.3 pounds, Zep 0.88 pounds and All-Clad 1.2 pounds. Size runs from 12 ounces of powder to 24 fluid ounces. Those figures describe the package, not how the cleaner works on a surface, and the sheet carries no coverage figure for any of them.

The table does not tell you how any cleaner behaves on a surface. No maker publishes a coverage area, a dry time or an ingredient list, and the words pH-neutral are a claim rather than a number. The table also cannot show which cleaner suits black stainless, since only Therapy states that surface in its published features.
What Each Cleaner Is Stated to Do
Surfaces each maker lists
Therapy lists appliances, grills, sinks, refrigerators, microwaves, stoves, range hoods and trash cans, and states the formula is pH-neutral. It also states the cleaner is a specialist for black stainless steel and leaves a protective barrier against fingerprints, dust, dirt and smudges. Those are the maker’s words about what the product is for.
Weiman lists stainless steel kitchen appliances, sinks, trash cans, grill exteriors, backsplashes and countertops, and states a pH-neutral formula. Zep lists appliances, grill exteriors, steel and other metal surfaces, and adds chrome and aluminum. Sprayway lists stainless steel appliances and surfaces plus window frames, trim, kick plates, doors and chrome.
Forms and how they are applied
Therapy and Weiman are liquids with a cloth in the package. Therapy includes a 16 by 16 inch microfiber cloth. Weiman publishes a two pack kit with a microfiber cloth and states no rinsing is required when the spray is wiped in the direction of the metal grain and buffed with a soft, dry cloth.
Zep is a 14 ounce liquid stated to polish as it cleans. Sprayway is a 15 ounce water-based spray stated to foam and not drip. All-Clad is a 12 ounce powder for stainless and aluminum cookware, applied to brushed or polished exteriors, in a container with a press-close sealing cap. Each form suits a different motion and a different surface.
Where the Published Claims Diverge
Restrictions and exclusions
Zep states it is not for use on natural stone surfaces or food contact surfaces. All-Clad states it is not for hard anodized, copper or nonstick cookware. Those two lines remove whole categories of surfaces from each product. Therapy, Weiman and Sprayway list no such exclusion in their published features.
That difference matters more than any dimension on the sheet. A cleaner that is ruled out for food contact surfaces cannot be used on a cooking surface, and a powder ruled out for nonstick cannot be used on a nonstick pan. Read the stated restriction before the stated shine.
Protective barriers and smudge claims
Therapy states a protective barrier against fingerprints, dust, dirt and smudges, and states the product is a scratch inhibitor. Weiman states a protective barrier that repels fingerprints, dust and smudges. Sprayway states the formula resists fingerprint smudges. Those are claims about what the maker says the product leaves behind.
Zep states it dissolves fingerprints, water marks, dirt, smudges and soil and leaves no residue, without stating a barrier. All-Clad states it removes burnt-on food and restores shine on cookware. None of these are measurements, and no maker publishes a duration for how long a barrier lasts.
Which One Fits Your Kitchen
Black stainless steel owner. Therapy is the only pick whose published features state it cleans black stainless steel. It also states a pH-neutral formula and includes a 16 by 16 inch microfiber cloth with a 16 fluid ounce bottle.
Someone who wants a kit with a cloth. Weiman publishes a two pack kit with a microfiber cloth and states no rinsing is required when the spray is wiped along the metal grain and buffed with a soft, dry cloth.
Chrome and aluminum in the mix. Zep lists chrome and aluminum alongside stainless steel and states it polishes as it cleans. The maker also states it is not for natural stone or food contact surfaces.
Water-based spray preference. Sprayway states a water-based formula with foaming action that will not drip, and lists window frames, trim, kick plates and doors in addition to appliances.
Cookware exteriors. All-Clad publishes a 12 ounce powder for stainless and aluminum cookware exteriors, in a container with a press-close sealing cap. The maker states it is not for hard anodized, copper or nonstick cookware.
What We Could Not Verify
Several figures a buyer might want are simply not on the sheet, and the makers do not publish them.
- No maker publishes a coverage area per bottle, canister or powder tub.
- No maker publishes a pH value, only the words pH-neutral where the claim is made.
- No maker publishes a dry time or a cure time for any protective barrier.
- No maker publishes a shelf life or an expiration date for any of the five.
- No maker publishes a full ingredient list for any of the five.
- No maker publishes a second size for the same product, so the listed size is the only one.
