Surface Cleaning Spray recipe
This is the cleaner I reach for most, and one of the easiest DIY swaps to make.

It is a simple soap-based spray for everyday surface cleaning. Use it as your first-step cleaner before acid-based sprays for glass, mineral marks or soap scum.
Best used on:
- Kitchen benches and cupboards
- Bathroom surfaces (vanity, sink, tiles)
- Walls and doors
- Light switches and door handles
- Spot cleaning carpets and rugs
- Skirting boards
- Kids’ muddy feet (yes, really
The recipe
Simply add the Castile soap, water and essential oils, if using them, in a 500ml spray bottle.
Adding the soap last helps reduce bubbles. Gently tip the bottle to mix.

Good to know
Shelf Life
Undiluted Castile soap can last up to 2 years when stored correctly. Once diluted with water, the water becomes the limiting factor. Make small batches and use within six months. Store in a clean, sealed bottle.
Surfaces
This soap-and-water spray is suitable for most washable household surfaces and can be used anywhere there is a need to clean everyday dirt, grease or residue. The main thing to watch is the essential oil content. If using essential oils on delicate, porous or unfamiliar surfaces, test first or leave them out.
Don't mix with Acids
Do not mix Castile soap with vinegar or citric acid. Soap is alkaline and acids neutralise it, creating a cloudy residue that does not clean properly and may leave marks on surfaces.
Why this works
| Ingredient | What it does |
|---|---|
| Liquid Castile soap | Your surfactant, the ingredient that does the actual lifting. Surfactants work by dropping the surface tension of water so it can get in underneath oil and dirt instead of beading over the top of it, then hold that grime in suspension so it rinses away instead of redepositing on your clothes. |
