As an added bonus, I now save and reuse more thinner than I had in the past, and it's kept fumes down, so that the wife no longer complains, and it reduced cleanup rags to almost nothing. I made my cleaner in less than one hour, from materials I had laying around, so no purchases were needed, but I would guess it could be made for less than 2 or 3 bucks if you had to buy the brass tubing and hose. Empty and cleaned 4-oz. Appropriate sized hose for connection to airbrushes siphon tube and end of plastic bottle. Make sure its compatible with thinner used.
Directions Make sure can is clean and washed and free of any residual liquids.
Wash with soap and water, and allow to dry. Make it snug so it holds the tube when it's inserted. Now solder both of these brass tubes in place. Your brass tube and hose sizes may vary as to your airbrush, and plastic bottle or funnels sizes. I found the dimensions given suitable for Paasche brushes, and the 4 oz.
