DIY All-Purpose Cleaner: 3 Recipes That Actually Work (With Cost Per Bottle)

Most DIY cleaner posts recycle the same untested recipe: vinegar, water, vibes. We made three different formulas, tested each one on grease, soap scum, and glass, and priced every bottle to the cent. One of them is genuinely great. One of them will ruin your granite. Here's the full breakdown.

Why Most DIY Cleaner Recipes Fail (the pH Problem)

Cleaning is chemistry, and the recipes that fail usually fail for the same reason: pH mismatch. Vinegar is an acid, which makes it excellent at dissolving mineral deposits and soap scum — but acids etch natural stone (granite, marble, travertine), dulling the seal and the finish. Meanwhile, the internet's favorite "add baking soda AND vinegar!" trick is theater: the two neutralize each other into salty water with a fun fizz.

The fix isn't one magic bottle. It's matching the formula to the surface. That's why we tested three recipes instead of one:

• Recipe 1: Vinegar-based — the everyday workhorse for laminate, tile, and sealed surfaces that aren't stone.
• Recipe 2: Alcohol-based — the stone-safe formula for granite and marble.
• Recipe 3: Castile-soap degreaser — the grease specialist for stovetops and range hoods.

Safety note for all three: never mix vinegar with bleach (creates chlorine gas) and never mix rubbing alcohol with bleach. These recipes contain neither — just don't freestyle them into your existing cleaning routine without checking.

Head-to-Head Test Results: Grease, Glass, Soap Scum

We tested all three on the same three messes, scoring 1–5 (5 = effortless, 1 = gave up):

• Baked-on stovetop grease: Recipe 3 scored 5 — it melted through in two minutes. Recipe 1 scored 3 (needed scrubbing). Recipe 2 scored 2 (not its job).
• Bathroom mirror + glass: Recipe 2 scored 5 — streak-free with a microfiber cloth. Recipe 1 scored 4 (tiny bit of haze if over-applied). Recipe 3 scored 2 (soap film — wrong tool).
• Shower-door soap scum: Recipe 1 scored 5 — the vinegar dissolved it in one pass. Recipe 2 scored 3. Recipe 3 scored 4 (good, but needed the rinse step).
• Sealed granite counter (daily crumbs + smudges): Recipe 2 scored 5. Recipes 1 and 3 were disqualified — vinegar and washing soda both risk the seal over time.

The pattern: each recipe wins its home turf and is mediocre elsewhere. That's the honest truth about DIY cleaners — there's no single bottle that does everything, just like there's no single store-bought bottle that does either.

Printable Label + Dilution Cheat Sheet

Tape this to the inside of your under-sink cabinet:

• Green label — Recipe 1 (vinegar): counters (not stone), tile, sinks, trash cans, shower scum. Never stone. Never with bleach.
• Blue label — Recipe 2 (alcohol): granite/marble, stainless steel, glass, mirrors. Your stone-safe everyday bottle.
• Orange label — Recipe 3 (castile + washing soda): stovetop, range hood, greasy buildup. Rinse after. Never stone.

Batch math for a year: a household that goes through one spray bottle a month spends ~$48/year on store-bought cleaner. The DIY versions run ~$5–10/year total, and you'll never throw away another trigger bottle — just keep two or three reusable spray bottles in rotation.
