Castile soap vs detergent bench sprays: what's the real difference?

Castile soap is a real soap made from plant oils; most bench sprays use synthetic detergents made in a lab. Both can clean, but castile soap does it with named, plant-based ingredients that rinse cleanly, while many detergent sprays rely on undisclosed surfactants and “fragrance.” On a food-prep surface, that difference is worth understanding.

“Surfactant” and “soap” get used as if they're the same thing. They're not, and the distinction is genuinely useful when you're choosing what to wipe over your bench.

What is castile soap, actually?

Castile soap is a traditional soap made by saponifying plant oils — in AEOC's spray, olive and coconut oil. It's “real soap” in the old sense: plant oils turned into a cleaning agent, with nothing synthetic standing in.

The name comes from the Castile region of Spain, where olive-oil soap has been made for centuries — so this isn't a new “clean beauty” invention, it's one of the oldest cleaning technologies we have. Saponification is the reaction that turns oils and an alkali into soap and glycerine; the finished soap lifts grease by surrounding oily residue so it wipes away. Because it's built from recognisable plant oils, you can name every part of it, which is exactly what you can't do with most synthetic detergent blends. AEOC uses castile soap as the base of its bench spray for that reason: it cleans well and it's fully nameable.

What are synthetic detergents, and why are they everywhere?

Synthetic detergents are lab-made surfactants that clean cheaply and foam impressively — which is why most supermarket sprays use them. They work, but they come with trade-offs you don't always see on the label.

Detergents like SLS (sodium lauryl sulfate) are inexpensive, high-foaming and effective, so they dominate mass-market cleaning. The catch is threefold: they're often listed only as generic “surfactants,” they can leave a residue film on surfaces, and some are harsher on skin and sensitive households. None of that makes every detergent dangerous — but it does mean you're often cleaning your food-prep bench with ingredients you can't identify. Foam, in particular, is theatre: it feels like cleaning power, but it's not the same as it. A lower-foaming soap can clean a bench just as well.

Which is better for a kitchen bench?

For everyday food-prep surfaces, a castile-soap spray gives you honest cleaning power with ingredients you can read — and that's the deciding factor for most people who switch.

Castile soap lifts grease and rinses cleaner than many synthetic detergents, leaving less film on the bench. Paired with pure essential oil for scent, the whole spray stays nameable end to end. It's also gentle enough for daily use in homes with kids and pets, without harsh fumes. The one honest note: real soap is lower-foaming, so if you associate mountains of suds with “clean,” you'll need to unlearn that — the bench will be just as clean with far less foam. For a food-prep surface, ingredients you can name beat suds you can't.

Castile soap vs synthetic detergent sprays

A 130-year-old, five-generation maker gets to say this without spin: AEOC was among the first in Australia to build cleaning products on natural liquid castile soap — not because it's trendy, but because real soap has always cleaned kitchens honestly.

Frequently asked questions

Is castile soap better than detergent for cleaning?
For everyday kitchen cleaning, castile soap cleans effectively with named, plant-based ingredients and rinses cleaner than many synthetic detergents. Detergents can clean too, but are often undisclosed and can leave a film.

Does castile soap clean as well with less foam?
Yes. Foam feels like cleaning power but isn't the same thing. Castile soap lifts grease with far less foam, and the bench is just as clean.

Is castile soap safe on food-prep surfaces?
Yes. It's a plant-oil soap designed for everyday surfaces; wipe with a damp cloth after spraying, as you would with any cleaner.

What is SLS and is it in AEOC bench spray?
SLS (sodium lauryl sulfate) is a common synthetic detergent. It is not in AEOC's bench spray, which is built on castile soap and contains no SLS, parabens or synthetic fragrance.

Why do detergent sprays foam more?
They're formulated with high-foaming synthetic surfactants because suds feel like cleaning. Real soap foams less but still lifts grease effectively.
