What not to do: you grab the tube, try to twist the cap hard, again and again, and twist the body of the tube instead. You repeat this a few times and the tube bursts. I know it happens... I have done it.
There are better ways to get to your precious locked away paint.
1. The smarter way with your hands
Use a rag or a paper towel to get a better grip and hold the tube by its upper part, just below the cap. This handling reduces the risk of twisting the body of the tube.
If it does not work that way, you still have two other methods to try.
2. With a plier
Same method as before, but this time you grip the cap with a plier.
This method works well on larger tubes because of their bigger cap.
3. The hot bath method
My father tought me this method and it works every time.
- Put the kettle on and then pour the hot water in a jar (not any that you plan to use for food – paint contains harmful chemicals)
- Dip the blocked tube upside down in the hot water and let it soak for a few minutes.
- Remove the tube from the hot water and unscrew the cap. Use a rag to get a better grip. The cap should come off easily. If not, let the tube soak for longer.
- Clean the inside of the cap and the screw on the tube with a rag and a palette knife. This way it will close properly.
