Plastic Bottle to Keep a Wet Paint Brush




A simple way to make a cup for a wet paint brush, is to cut a plastic bottle in half. The smart thing here is to keep the top half, with its cap on, and place it over the bottom half. This way it holds the paint brush in place, and keeps the smell of the solvent from spreading.

Step 1: Cut the Bottle in Half

Pick a plastic bottle of suitable size for the paint brush. Cut it roughly in half with a knife or scissors (keep the cap on!). Try to cut it where there is a bulge, so that the top part can be made to fit over the bottom part.

Step 2: Put It to Use

Fill the bottom half to the height of the brush part, with whatever liquid you use. Then put the brush in, and put the top half on!

Step 3: Ready! Be Careful!

Your paint brush preserver is ready. Virtually no smell leaks out (and thus no evaporation losses). But be careful with the contents, don't lift the bottle with the cap, and don't topple it over!

    Seems to me this idea would be best serving the bristles of the brush by having a hook in the top half so that you put to top on to get the brush in, so that the brush remains suspended in the fluid.

    Thank you for reading and commenting my first and only Instructable! I appreciate that.
    You are right in that the brush should not rest on its bristles. Much better advice than mine*) has been available for decades, since the age of Popular Mechanics in the '50s, and up to the Internet of today. My idea was just a quick fix for saving the brush until tomorrow. Also no room for a hook in the cut-off bottleneck.
