Borax 3.5%

Borax 3.5% is a mild solution of sodium borate, often used as a cleaning agent, laundry booster, or in various household applications. This white, powdery substance dissolves easily in water and is valued for its effectiveness in softening water, controlling odors, and as a general-purpose cleaner.

Borax 3.5% – A Simple, Reliable Solution

Borax 3.5% is a boron-based liquid used in farming, cleaning, and manufacturing. It contains 3.5% boron, making it useful wherever accurate boron levels or mild cleaning power are needed. You’ll find it used across homes, farms, and factories in Australia.

It’s stable, easy to work with, and does what it’s meant to—whether you’re treating soil, cleaning equipment, or handling industrial processes.

What It Is

Borax 3.5% is a water-based solution made from sodium tetraborate decahydrate. People just call it “borax.” It’s made from natural minerals that include boron, sodium, oxygen, and water.

You can mix it with water, and it works well in different settings. Some use it at home. Others use it in large-scale operations.

What It’s Used For

  • Farming: Adds boron to soil when crops are lacking it. This helps with plant health and yield.

  • Cleaning: Acts as a mild cleaner and deodoriser in commercial cleaning products.

  • Manufacturing: Used in glass and ceramic production. It helps those materials handle heat and chemicals better.

  • Corrosion prevention: Helps stop rust and metal damage in some systems.

  • Laundry and metallurgy: Boosts cleaning in laundry products and helps in metalwork processes.

It’s one of those products that quietly shows up in a lot of places.
