Dr. Bronner — The Universal Soap Guide

Walk into any natural health shop and you’ll likely spot the instantly recognisable bottles from Dr. Bronner's  packed with tiny text, bold statements, and the promise that one soap can handle almost everything. From showering and shaving to washing dishes and mopping floors, it’s often called a universal soap and not without reason.

What makes it different is simple: this isn’t a ready-to-use product like a typical body wash or cleaner. It’s a highly concentrated Castile soap designed to be diluted for different jobs. Once you understand how to mix it correctly, one bottle can replace a whole shelf of products saving money, space, and packaging.

Why Dilution Is the Secret

This is a concentrate first and a cleaner second. That’s what gives it such wide-ranging uses, but also why dilution matters.

Diluting properly:

• Makes it gentler on skin and hair

• Improves performance for each task

• Prevents overuse

• Helps each bottle last far longer

Think of it as a base formula you customise depending on what you need to clean.

Everyday Personal Care (Simple & Effective)

🚿 Shower & Body Wash

A small squirt on a wet cloth, sponge, or into your hands is enough. It lathers quickly, so don’t overpour.

🧼 Face Cleansing

Use just 2–3 drops on wet hands, work into a light lather, and rinse thoroughly.

🫧 Foaming Hand Soap

Fill a foaming dispenser with:

• 1 part soap

• 3 parts water

Shake gently to combine.

💇 Hair Washing

• Short hair: a few drops directly into wet hair

• Longer hair: mix up to ½ tablespoon with water first

Tip: In hard water areas, a mild acidic rinse afterwards (such as diluted apple cider vinegar) can improve softness and shine.

🪒 Shaving

Lightly lather before shaving:

• Face: ~10 drops

• Underarms: ~3 drops

• Legs: ~½ teaspoon

Kitchen & Household Cleaning

🍽️ Washing Up

Add 1–2 tablespoons to a sink of hot water
Or
Pre-mix at 1:10 soap to water in a washing-up bottle.

🧽 All-Purpose Surface Spray

Mix:

• ¼ cup soap

• 1 litre water

Suitable for worktops and most sealed surfaces.

🔥 Hob & Greasy Areas

Use the same spray mix to cut through grease on cooker tops and splashbacks.

🪟 Windows & Mirrors

Add 1 tablespoon to 1 litre of water, spray lightly, then wipe or squeegee dry.

🚽 Toilet Cleaning

Pre-dilute roughly 1:4 with water and scrub with a toilet brush. Optional: add a few drops of tea tree oil.

For a standard wash load:

• Use ⅓–½ cup of soap

• Add 1 cup of vinegar to the rinse cycle

For HE machines, use about half these amounts. Baking soda can be added for extra deodorising.
