Alcohol-based cleaners: risks and uses

Introduction

From disinfecting countertops to sanitizing hands, alcohol-based cleaners have become everyday essentials. But like any cleaning product, they come with both advantages and drawbacks. Understanding their risks and uses can help you clean more effectively without unintended side effects.

1. What Are Alcohol-Based Cleaners?

These cleaners typically contain isopropyl alcohol or ethanol in concentrations ranging from 60%–90%. Their fast-acting formula makes them excellent at killing bacteria, viruses, and fungi.

2. Key Uses of Alcohol-Based Cleaners

Disinfecting Surfaces – ideal for frequently touched areas like doorknobs, phones, and keyboards.
Medical Settings – widely used in hospitals for sterilization and hand hygiene.
Quick-Drying Cleaning – perfect for electronics, as alcohol evaporates without leaving residue.
Personal Hygiene – found in sanitizers, wipes, and sprays.

3. Risks of Alcohol-Based Cleaners

Surface Damage – can strip finishes from wood, leather, or painted surfaces.
Skin Irritation – frequent use may cause dryness or cracks.
Flammability – alcohol is highly flammable, requiring safe storage and handling.
Limited Cleaning Power – while effective at killing germs, alcohol is less useful for heavy dirt, grease, or stains.

4. When to Avoid Alcohol-Based Cleaners

On delicate fabrics like silk or wool.
On leather jackets or upholstery (alcohol can cause cracking).
On natural stone surfaces such as granite or marble.

5. Safe Tips for Using Alcohol-Based Cleaners

Use in well-ventilated areas.
Always test on a small hidden area first.
Store away from heat sources or flames.
Pair with other cleaners for dirt and grime before disinfecting.
