Multi-Purpose Soap Spray

Amber glass spray bottle and castile soap in bottle for handmade cleaning surface sprays

The spray you go to first for everyday surface cleaning. 

Cleaning sprays come in every shape, size, fragrance and price, with plenty of claims attached. But most ready-to-use sprays have one thing in common: they are mostly water with a dash of synthetic surfactants.

This natural solution gives you peace of mind, knowing exactly what is being sprayed around your home — without compromising on results.

You can use it for:

  • Kitchen benches and cupboards
  • Bathroom vanities, sinks and tiles
  • Walls, doors and skirting boards
  • Light switches and door handles
  • Spot cleaning carpets and rugs
  • Muddy footprints and everyday marks

For an everyday surface cleaner, you need something gentle enough for regular use but powerful enough to work. Pure soap is one of the simplest low-tox, eco-conscious options. As a surfactant, it surrounds and lifts grease and dirt so they can be easily wiped away.

The downside is soap sprays can sometimes leave streaks on glass, mirrors and tapware, particularly in hard-water areas. That is where the second step Acidic Spray comes in.

The Recipe

500ml Makes / Yield
< 1 minute Time

Ingredients

  • Castile Soap
    Anywhere between 2–5% is best (10–25 mL). The dilution depends on how soapy you prefer the mixture or the job at hand.
  • Water
    Top with water to make 500 mL. Tap or pre-boiled water is fine. If you have hard water, use distilled or demineralised water.
  • Optional essential oil
    5–10 drops. Lemon, lemongrass or eucalyptus work well.

Method

  1. Add the water to a 500ml spray bottle, leaving enough room for the Castile soap.
  2. Add the essential oil, if using, followed by the Castile soap. Adding the soap last helps reduce bubbles.
  3. Replace the spray trigger and gently tip the bottle a few times to combine.

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

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.
