how to care for watercolour brushes – make your brushes last!

Watercolour brushes are delicate, precise, and (let’s be honest) often a bit of an investment. Whether you're just starting out or using high-quality, handmade brushes like the ones I use, taking care of them means they’ll keep performing beautifully for years. In this post, I’ll share my favourite tips for keeping watercolour brushes in top shape—from everyday rinsing to deep cleaning and storage. Learn how to best care for watercolour brushes and start preserving your art supplies today!

why you should care for your watercolour brushes

Watercolour brushes are built for precision. A clean, well-shaped brush lets you glide colour across paper, lift pigment gently, and create clean washes and soft edges. When your brush is looked after, you’ll notice the difference every time it hits the paper.

💧 Maintains water-holding capacity and pigment flow.
🖌 Makes painting easier, especially with layering and blending.
💸 Saves you money in the long run—no need to replace them constantly.

💡 takeaway: Happy brush = smooth strokes, soft blends, and more joy in your painting practice. So let’s learn how to care for watercolour brushes!

rinse your brushes after every painting session

Watercolour paint is gentle, but leaving any pigment to dry in your brush can shorten its lifespan fast.

💧 Swirl your brush gently in clean, lukewarm water after each use.
🖌 Gently reshape the bristles with your fingers.
📜 Lay flat or hang to dry—never store bristles-up while wet!

💡 takeaway: Letting water sit in the ferrule (the metal part) can loosen the glue and ruin your brush. A quick rinse = long-term happiness.

use gentle soap for a deeper clean

Every now and then, your brush needs more than a rinse. If it’s losing its shape or the bristles feel tacky, it’s time for a proper clean.

🧼 Use a mild, artist-safe brush soap or unscented baby shampoo.
🎨 Lather gently in the palm of your hand.
💫 Rinse thoroughly and reshape before drying.

💡 takeaway: Harsh detergents can damage delicate watercolour brushes—gentle is always better.

dry & store your brushes properly

The way you dry and store your watercolour brushes makes a huge difference to their longevity.

🤍 Lay them flat on a clean towel to dry.
🤍 Store flat or upright (once completely dry) in a roll, jar, or brush holder.
🤍 Keep them somewhere cool and dry—away from moisture and direct sunlight.

💡 takeaway: Proper storage = fewer bent bristles and more painting joy.

common mistakes to avoid

Watercolour brushes might be softer than oil or acrylic ones, but that also makes them more fragile.

🚫 Never leave them soaking in water—it breaks down the glue in the ferrule.
🚫 Don’t let paint dry in the brush—it stiffens the bristles and ruins the tip.
🚫 Don’t scrub or press too hard—watercolour is about flow, not force.
🚫 Never use watercolour brushes for acrylics or other thicker paints.

💡 takeaway: Treat them like tools, not toothbrushes!

my favourite watercolour brushes - the brushes i use every painting session!

When it comes to watercolour, I believe in using the best materials possible—and that includes brushes. That’s why I only use and recommend the professional-quality watercolour brush set available in my shop. I do have many, many (very expensive, squirrel hair) brushes available to me in my studio…but I still always reach for these ones.

& considering my professional as a veterinarian, they are completely animal-free, of course!

some alternatives - cheap watercolour brushes still do the trick!

Not everyone needs high-end brushes right away, and if you’re just starting out or painting for fun, cheap watercolour brushes are absolutely fine. There’s no need to invest in expensive brushes if you’re still learning the basics or experimenting with techniques.

🖌 Great for beginners – If you’re still figuring out how water behaves on paper, a basic set will let you practice without worrying about wear and tear.
💧 Perfect for loose or experimental painting – If you love abstract washes, splatter techniques, or casual sketching, cheaper brushes work just fine.
💰 Affordable and replaceable – You won’t feel guilty if they fray or get damaged, and you can easily replace them as needed.
🎨 Great for mixed media – If you use gouache, ink, or acrylics alongside watercolour, inexpensive synthetic brushes are a versatile option.

💡 Takeaway: While professional brushes offer better control and longevity, there’s nothing wrong with using budget-friendly options—especially when you’re just getting started!

🤍 6 piece sable hair watercolour brush set

something else to keep in mind when learning how to care for watercolour brushes...

Here’s what I do in my little home studio (with Alys curled up nearby, of course 🐶):

🫧 I rinse my brushes after every colour change (not just at the end).
☕️ I always paint with a cup of tea nearby (and try not to dip my brush in it).
📦 I store my brushes in a vintage pencil roll—it keeps them neat and safe.
🖌 I only use my handmade, synthetic brushes from my shop—they’re animal-free and perfect for watercolour. You can check them out here.

💡 takeaway: Find a little brush-care ritual that feels like part of your creative process.
