How to Rescue Misshapen or Frayed Paintbrushes with Gum Arabic

Admittedly, misshapen paintbrushes were less of a problem before I had young children. My kids love to paint along with me, and sometimes I don’t notice when they’re using (and abusing) the nice brushes! But even if your brushes aren’t at the mercy of a toddler, they can still lose their shape over time. Gum arabic is an easy fix.

Brushes before and after

Basically, gum arabic acts like a setting gel for bristles, holding them in place as they dry. Once the gum arabic hardens, it helps the bristles retain their shape, preventing fraying and splaying. Rinse it out, and the bristles will keep their new shape! In the ~2 minute video below, I’ll walk you through how to do it. (Written instructions follow!)

1. Gather Your Supplies

Begin by finding all of your brushes that could use some TLC. (If you’re restoring one, you might as well restore them all!) Then, source a gentle, sulfate-free shampoo. Grab your gum arabic and a small bowl or cup.

Gentle shampoo is imperative for avoiding bristle damage and keeping your brushes supple and soft. Look for natural and/or baby shampoos.

2. Wash the Paintbrushes

Add a dime-sized drop of shampoo to the bowl and use a paintbrush to gently mix it with about ½ cup of water. Then, swish each brush in the mixture to clean it. For extra-grimy brushes, apply a little shampoo directly to the bristles and lather them as you would your hair.

Next, either swish the brush off in a bowl of clean water or run it under the tap to remove all the shampoo. As you rinse off your brushes, lay them on a paper towel or a towel to absorb excess moisture.

3. Shape the Bristles

After cleaning your brushes, dip one into your jar of gum arabic, ensuring the bristles are fully coated. If some gets on the metal ferrule, don’t worry—it will wash off easily later.

It’s okay if your paintbrush is still damp when you dip it into the gum arabic.

Lift the brush out of the gum arabic and gently shape the bristles with your fingers. Think of it like styling hair—you’re using the gum arabic as a setting gel to keep everything in place.

As you shape your paintbrushes, place them in a cup to completely dry.

If you’re in a dry environment, your brushes will be ready in a few hours. In humid conditions, they’ll likely need to sit overnight.

4. Rinse

Now, gently swish each brush in clean water (1). Then, use your fingertips to gently encourage the gum arabic off (2). Dry the bristles in a paper towel or an absorbent cloth (3), and enjoy the fruit of your efforts (4)!
