Borax, or sodium borate, is a naturally occurring mineral compound best known as a laundry booster and water softener. Borax is also excellent as a multi-purpose household cleaner with many uses throughout your house including craft projects.
Although it has numerous industrial uses, in the home borax is used as a natural laundry booster, multipurpose cleaner, fungicide, preservative, insecticide, herbicide, disinfectant, desiccant, and ingredient in making “slime”. Borax crystals are odorless, whitish (can have various color impurities), and alkaline. Borax is not flammable and is not reactive. It can be mixed with most other cleaning agents, including chlorine bleach.
How Does Borax Clean?
Borax has many chemical properties that contribute to its cleaning power. Borax and other borates clean and bleach by converting some water molecules to hydrogen peroxide (H2O2). This reaction is more favorable in hotter water. The pH of borax is about 9.5, so it produces a basic solution in water, thereby increasing the effectiveness of bleach and other cleaners. In other chemical reactions, borax acts as a buffer, maintaining a stable pH needed to maintain cleansing chemical reactions. The boron, salt, and/or oxygen of boron inhibit the metabolic processes of many organisms. This characteristic allows borax to disinfect and kill unwanted pests. Borates bonds with other particles to keep ingredients dispersed evenly in a mixture, which maximizes the surface area of active particles to enhance cleaning power.
Even though it best known as a laundry booster, borax does much more, and once you discover how many things it is good for, you will want to keep a box handy. Here are just some of the everyday tasks it can handle:
Cleaning with borax
- Laundry: A cup of Borax in every load of wash along with detergent will boost the cleaning power of your detergent. Mixing cup of Borax with 2 cups of warm water and you have a stain remover that works on blood, chocolate, coffee, mildew and urine stains.
- Baby Diapers and Clothes: Presoak flushed-out, soiled diapers in a diaper pail filled with hot water and cup of Borax for 30 minutes before washing. It helps to reduce odors and stains and makes diapers more absorbent.
- Flea Control: Sprinkle Borax on carpet and let it sit for a few hours, or overnight, before vacuuming. Just keep the kids and pets out of the room until vacuumed.
- Deodorizing Garbage Disposals: Just sprinkle a few tablespoons down the drain and after 15 minutes or so, flush the drain with warm water.
- Clean and Deodorize Refrigerator: Dissolve one tablespoon of borax per quart of warm water and use it to wipe down the insides of the refrigerator.
- Deodorizing Bins: Soak the bin with a mixture of hot water and a cup borax to eliminate odors. After it has dried, sprinkle in more borax inside to help absorb future odors.
- Sinks, Bathtubs and Toilets: Borax alone is a great non abrasive cleanser, and when mixed with lemon juice into a paste, it can help to get rid of rust stains.
Borax to prevent brown heart in turnips
Borax is used to protect turnips against brown heart. it should be applied as a solution of 15g per litre of water and applied at a rate of 1 litre per 10 sq m.
Borax in cosmetics
Borax is used in many areas including cosmetics and toiletries. It is also used as a crosslinking agent to emulsify waxes and other paraffins used as a base for lotions, creams and ointments. How to prepare an emulsion: heat the oils in a double boiler. Dissolve the borax in hot water. Add the borax solution slowly to the hot oil, constantly stirring in one direction. Keep stirring until the creamy white emulsion has formed.
Borax as a buffering agent
Dissolved in water, Borax hydrolyzes to give a mildly alkaline solution and can be used to neutralise acids. It can be used in combination with strong alkilies to produce chemical compounds of lower pH. The relatively constant pH of Borax (approx pH 9.2) Dedahydrate solutions makes it an excellent buffering agent.
Borax in adhesives
Borax Decahydrate is part of the starch adhesive formulation for corrugated paper and paperboard, and is a peptising agent in the manufacture of casein-based and dextrin-based adhesives. It greatly improves the tack and green strength of the adhesive by crosslinking conjugated hydroxyl groups.
Borax in metallurgy
Borax Decahydrate has the ability to dissolve metal oxides and is exploited in the recovery of metals such as brass, copper, lead and zinc from scrap or smelting slag. In Iron metallurgy, Borax Decahydrate is used as a flux to prevent oxidation at the surface of the molten iron. In other metal working processes like welding, brazing, and soldering, Borax is used to cover the metal surfaces. This prevents any oxidation occuring by excuding air and moisture contact. It also can be used as a cleaning agent.
Borax for corrosion prevention
Borax finds many uses as a corrosion inhibitor in aqueous sytems as it can prevent oxidation of ferrous / Iron metals. Typical applications are in engine coolants, antifreezes and water treatments. Borax is highly soluble in MEG / ethylene glycol and can neutralise acids that are produced from the decomposition of the MEG prevention acidic corrosion of the metal surface.
Other industrial uses for borax
Borax is used: In the extraction of gold from metals. As a flame retardant and for putting out small fires without the risks of flare-up. A carrier for herbicides. As a stbiliser and bonding agent for specialist abrasives. As a neutraliser and carrier in the production of metal wire.
