Hello, artists! Today, we’re going to talk about a crucial aspect for everyone who uses spray paint with stencils: maintaining your spray paint caps. Whether you’re an interior design enthusiast, a street artist, or an illustrator, keeping your caps clean is essential for flawless results. So, how do we do it?

The Importance of Cleaning Your Caps

Why is it important to clean your Spray Paint caps?

Firstly, a clean cap ensures a neat and precise application, which is particularly important when working with stencils to achieve clear lines and patterns. Plus, it prevents paint wastage and saves you from frequently buying new caps.

Fine Caps: Special Attention Required

Fine caps, like those used for precise details in stencil work, have small openings that can easily clog. Special attention is, therefore, necessary for these small tools.

Tips for Optimal Maintenance of Your Caps
