Making a habit of cleaning your nail scrub brush after each use and deep cleaning it regularly is the best way to keep it hygienic and prevent stubborn buildup or mildew.

Caring for your nail brush properly helps it last longer, stay fresher, and keep your nails clean. It also means getting more life out of something you already own, which is a great way to live more sustainably.

In this guide, we’ll share everything you need to know about cleaning a nail scrub brush, from everyday care to cleaning and disinfecting.

Are Nail Brushes for Scrubbing Nails?

Nail brushes are a gentle yet effective way to remove grime and dirt,keeping your nails healthy. Designed with varying bristle lengths, they make it easy to gently clean under nails and along the delicate sides where the nail meets the skin.

Nail brushes are often kept in damp environments likebathrooms or by the sink and might get a lot of use, especially if you’re a gardener or cleaning lots of little fingers, so dirt can build up quickly. That’s why it’s important to clean them regularly to keep them hygienic and effective.

The Quick Clean (Do This After Every Use)

Little and often is the best way to prevent buildup and keep your nail scrub brush fresh. This quick clean can be done after every use, or in the shower:

  1. Rinse the bristles under warm running water.

  2. Add a small amount of soap and work it through the bristles with your fingers.

  3. Rinse the brush until the water runs clear.

  4. Shake off excess water and allow your brush to air dry away from the damp sink.

The Deep Clean: How to Remove Buildup From Brushes

Nail brushes come into contact with sebum, dead skin cells, hand cream, soap scum, dirt and dust, all of which can build up around the bristles over time. To deep clean your brush and remove stubborn residue:

  1. Fill a bowl with warm water and a few drops of washing-up liquid.

  2. Soak the bristles in the bowl for around 15 minutes.

  3. Gently scrub the bristles with an oldtoothbrush, starting at the base.

  4. Rinse thoroughly and leave the brush to air dry.

Do You Need to Disinfect a Nail Brush?

Nail brushes collect grime and are often kept in dampbathrooms, which can make them a breeding ground for bacteria over time. Disinfecting your nail brush once a week if it’s used regularly, or once a month for occasional use, helps keep it hygienic and smelling fresh.

One of the simplest ways to disinfect a nail brush is to use70% rubbing alcohol. If you have 99.99%, you can dilute it to 7 parts rubbing alcohol to 3 parts water.

Spray your nail brush with the alcohol and allow it to air dry completely. The water content in 70% rubbing alcohol helps slow down evaporation, giving it enough contact time to effectively kill most bacteria.

For a more natural option, briefly soaking the bristles inwhite vinegar before rinsing thoroughly can also help reduce bacterial buildup.

How to Prevent Mould on Your Nail Brush

Natural materials need a little extra care, so you may find black patches of mould or mildew on your nail brush if it remains damp for too long or is stored in a room with high humidity.

Cleaning your nail brush regularly helps remove the dirt and grime that mould feeds on. It’s also important to let your nail brush dry completely after use and avoid storing it by the sink where it’s easily splashed with water.

Humid bathrooms promote mould growth, so storing your nail brush somewhere dry can help it last for longer.

When to Replace Your Nail Brush

With proper care, a good-quality nail brush can last a long time. However, it may be time to replace yours if:

  • The bristles are permanently splayed

  • The brush smells unpleasant even after cleaning and disinfecting

  • Visible mould appears

If you choose a natural nail brush made with awooden handle and sisal fibre bristles, the good news is that it’s completely biodegradable at the end of its life. You can dispose of it as wood waste, compost it, or leave it to break down naturally in your garden - just bear in mind that the wooden handle will take longer to decompose than the bristles.

Keeping Your Nail Scrub Brush Clean

Cleaning your nail scrub brush doesn’t have to be complicated. A quick rinse after each use, a regular deep clean and proper drying are all you need to keep your brush hygienic and fresh for scrubbing your nails.
