Common Problems When You Clean Makeup Brushes

Even with the best intentions, you might run into a few issues. Here’s how to troubleshoot the most common problems related to makeup brush and tool maintenance.

Bristles Are Shedding

If you notice a few bristles falling out after washing, it could be a sign that water has weakened the glue in the ferrule. Ensure you are always rinsing with the bristles pointed down. It can also happen with new brushes (a few loose bristles are normal) or with very old brushes that are nearing the end of their life. Be extra gentle when lathering and rinsing.

The Brush Dried in a Weird Shape

This happens when the bristles aren't properly reshaped after washing. If a brush has already dried splayed or misshapen, you can often fix it by quickly re-wetting just the bristles, carefully reshaping them with your fingers, and letting them dry again correctly (flat, with the head over an edge). Using a mesh brush guard during drying is the best way to prevent this.

Brushes Take Too Long to Dry

Dense, large brushes can take a full day to dry. To speed up the process, ensure you squeeze out as much water as possible with a towel before laying them out. Drying them in a well-ventilated room, rather than a humid bathroom, can also help. Hanging them upside down using a brush drying rack provides the best air circulation for the fastest results.

A Musty Smell Lingers After Drying

A mildew or musty smell means the brushes didn't dry quickly enough and bacteria started to grow. Unfortunately, this may mean you need to wash them again. To prevent it, ensure they are not left in a damp, enclosed space and that air can circulate freely around the bristles as they dry.

Advanced Tips for Makeup Brush And Tool Care

Once you've mastered the basics, these advanced techniques can help you tailor your cleaning routine to your specific tools and needs.

Caring for Natural vs. Synthetic Bristles

Synthetic bristles (made of nylon or taklon) are very durable and can handle most gentle cleansers. Natural hair bristles (like goat or squirrel) are more delicate, much like human hair. For these, it’s best to use a very gentle baby shampoo. You can even follow up with a tiny amount of hair conditioner, rinsed thoroughly, to keep them extra soft.

Sanitising Your Brushes

For a deeper sanitisation, especially if you share brushes or have acne-prone skin, you can use isopropyl alcohol. After the brush is fully washed and dried, lightly spritz the bristles with a 70% isopropyl alcohol solution in a spray bottle. Let it evaporate completely before using the brush. Do not soak the bristles in alcohol, as this can be too harsh and damage the glue.

Using Brush Guards for Perfect Shape

Brush guards are small, expandable mesh sleeves that you slide over the head of a clean, damp brush. They gently hold the bristles in their perfect shape while they dry, preventing any splaying. They are particularly useful for large, fluffy powder brushes and delicate fan brushes.
