In homes, hospitals, and workplaces across the UK, isopropyl alcohol plays a key role in hygiene and maintenance. Known for its fast-drying and disinfecting qualities, it’s widely used across industries. Its affordability and effectiveness make it a go-to choice for cleaning, sterilising, and more.
Let’s dive deep into the most common and impactful uses of isopropyl alcohol, backed by facts and best practices.
What Is Isopropyl Alcohol?
Isopropyl alcohol (commonly called rubbing alcohol) is a clear, colourless liquid with a strong smell. It contains 70% to 99% alcohol content, depending on the product. It evaporates quickly and doesn’t leave residue behind.
In the UK, isopropyl alcohol is sold in pharmacies, hardware stores, and online. It’s also listed on many medical product labels and industrial cleaners.
1. Powerful Disinfectant for Surfaces
One of the most effective uses of isopropyl alcohol is killing bacteria, viruses, and fungi. With 70% concentration, it breaks down cell walls and eliminates harmful microbes.
Use it to wipe kitchen counters, doorknobs, and electronic devices.
It’s a hospital-grade solution trusted for its sterilising power.
According to the NHS, frequent disinfecting helps reduce the spread of flu and other viruses. Isopropyl alcohol offers a quick and reliable way to stay protected.
2. Ideal for Electronic Cleaning
Electronics collect dust, oils, and germs over time. Since isopropyl alcohol dries fast and leaves no residue, it’s perfect for:
Computer screens
Mobile phones
Remote controls
Keyboards
Apply a small amount to a microfiber cloth—never pour it directly on the device. Use light pressure and let it dry naturally.
3. First Aid and Skin Use
You’ll find isopropyl alcohol in most UK first aid kits. It’s commonly used to:
Clean small wounds
Sterilise tweezers or scissors
Reduce skin oil before applying bandages
Dr Sarah Welch, a UK-based general practitioner, notes:
“Rubbing alcohol is a reliable and fast-acting disinfectant for minor injuries. It’s useful for home care but should never be applied to deep cuts.”
Avoid using it on broken skin too often, as it may cause dryness or irritation.
4. Grease and Ink Remover
Cleaning up oil stains, ink marks, or permanent marker? Isopropyl alcohol does the job without damaging most surfaces.
Use it for:
Removing glue residue
Lifting ink from whiteboards or clothes
Cutting through sticky substances on tiles or tools
For best results, rub with a cloth soaked in isopropyl alcohol and rinse with water.
5. Sanitising Beauty Tools and Brushes
Makeup brushes and beauty tools collect bacteria fast. Cleaning them with soap isn’t always enough. That’s where isopropyl alcohol shines.
Dip tweezers or clippers in 70% alcohol for 30 seconds.
Spray your makeup brushes weekly and let them air dry.
This reduces acne breakouts and skin irritation caused by dirty tools.
6. DIY Hand Sanitiser
During shortages, many UK residents turned to homemade sanitiser. The NHS advises that hand sanitiser must contain at least 60% alcohol.
Here’s a simple formula:
2 parts isopropyl alcohol (at least 70%)
1 part aloe vera gel
Mix well and store in a clean container
Remember, handwashing with soap remains the best method, but this works well when soap isn't available.
7. Mould and Mildew Treatment
Bathrooms, kitchens, and windows often struggle with mould. Spray 70% isopropyl alcohol directly on affected areas. Let it sit for 10 minutes, then scrub with a brush.
It kills fungal spores on contact.
It’s safer and less toxic than bleach fumes indoors.
Repeat weekly to prevent regrowth.
How Does Isopropyl Alcohol Compare to Other Cleaners?
Let’s compare isopropyl alcohol to bleach and hydrogen peroxide:
Isopropyl alcohol: Quick-drying, safe for electronics, low smell
Bleach: Strong disinfectant but produces fumes
Hydrogen peroxide: Safe for wounds, slower to evaporate
For everyday surface cleaning, isopropyl alcohol is often the preferred choice. It balances safety and strength well.
Safety Tips for Using Isopropyl Alcohol
While isopropyl alcohol is safe when used correctly, remember these tips:
Always keep it away from open flames. It’s highly flammable.
Store it in a cool, dark place.
Don’t mix it with bleach. The combination can release harmful fumes.
Use it in a well-ventilated area to avoid inhaling too much vapor.
Always read the product label and use protective gloves when necessary.
