How Do You Clean Paint Brushes for Miniatures?
Is cleaning a hobby all in its own? Not really!
For how to get paint out of brushes, we start with a glass cup (or shot glass) and a bottle of Winsor & Newton Brush Cleaner. Pour in a decent amount and add a little more for each extra brush you want to clean. It’s not an exact science, so you have to do it a couple of times to get the exact amount you need.
One big thing to note is to keep this away from pets and children, as drinking it would not be good, to say the least.
After the cup is full, set brushes in the solution and tack them to the side of the glass with some poster tac. If you let the wood of the handle brushes sit in the solution, it will actually damage the handles. Likewise, letting them sit on the bottom of the glass with the brush bristles smashed and possibly damage the ferrule that attaches them to the handle, as well. This is super detailed work, just get them in the solution!
Allow your brushes to rest in the solution for about 5-10 minutes. Not a long time, so pay attention.
Step 2
After you take them out, wash them off with water and clear off the excess water. Then, take some Jentastic Drunken Brush Goop Conditioner, Pink Brush Soap, or Masters Cleaner and put some in your palm with the brush like the picture above. Next, run the bristles through it in the folds of your palm until it looks smooth, then wash it off again.
After they have been cleaned and conditioned, these brushes look great! You can also apply the conditioner regularly to your brushes to extend their life (don’t do this with paint thinner or your brushes won’t last long). If you’re asking, how to clean dry brush, this works perfectly for drybrushes as well, not just those fine tip ones!
Top 5 Cleaning Tips For Paint Brushes For Miniatures
1. Remove Residual Paint with Water. After every painting session, make it a habit to swish your brushes in clean water. This simple yet effective step helps remove any lingering acrylic paint from the bristles. Using a dedicated water pot can enhance this process, ensuring that your brushes are thoroughly rinsed.
2. Use Brush Soap After Every Paint Session: Invest in a high-quality paint brush soap and cleaner, such as Jentastic Drunken Brush Goop Conditioner, Pink Soap Brush Cleaner, or Master’s Brush Soap & Cleaner. This cost-effective solution is a game-changer when it comes to preserving your brushes. Using brush soap regularly ensures your brushes remain in top-notch shape. A quick brush wash will do the trick.
3. Dry Your Brushes Correctly: The way you dry your brushes matters. Whenever possible, hang your brushes vertically with the bristle tip down. Alternatively, you can lay them horizontally on a brush rest. This is especially important for tiny paint brushes.
4. Deep Cleaning with Brush Restorer Solution: For thorough deep cleaning, especially if you notice dried acrylic paint on the bristles, consider soaking your brushes up to the ferrule in a solution like Winsor & Newton’s Brush Restorer. This solution works wonders in reviving your brushes, ensuring they maintain their pristine condition.
5. Opt for Cool or Lukewarm Water: When cleaning your brushes, always use cool or lukewarm water. Avoid hot water, as it can potentially damage the delicate bristles and the brush itself.
When Should You Clean Your Paint Brushes for Miniatures?
After each painting session, perform a thorough wash and rinse with clean, cool, or lukewarm water. Using brush soap is highly recommended for optimal results.
To keep your small paint brushes in tip-top condition, adhere to the following cleaning schedule:
- After Every Painting Session
- Weekly or Every 3-4 Hours of Painting: For deeper cleaning, especially if you’ve been painting for extended periods, consider using a liquid brush cleaner. This step is essential to remove paint that may have penetrated deeper into the bristles, such as up in the ferrule.
