I never used to even consider paint tube hygiene to be of any concern in my painting. I just put up with the built up dried, gooey, messy paint that collected around the neck of my paint tubes, the difficulty this caused in getting the caps to screw on properly and even broken paint tube caps. I just thought this was the way all painters lived: simply a cost of doing business in this bohemian world.
After a lifetime in this “dirty” world, I recently discovered a path to a cleaner life. It requires a change of habit and a bit of diligence, but I think I’m up for the task. I’m tired of grinding concentrated bits of pigment into the floor of my studio or tracking it through the house, when a bit of this goop, unseen, falls from the neck of a tube and ends up on the bottom of my shoe.
How do you adapt this change in lifestyle? You start by removing the paint goop from the neck of each paint tube in your paintbox. If the tube is almost empty or the gunk is too difficult to remove, just give up on this tube and begin your new regimen of hygiene, when you’ve used the color up and replaced it with a new tube. Once the paint is removed from the neck, apply a drop of linseed, walnut or safflower oil (your oil of choice) to the threads on the neck of the tube. You won’t believe how smoothly the cap now screws on and off. From there, it’s just a matter of wiping away wet paint from the threads, whenever it begins to collect and applying the oil.
Stay the course and your paint tubes will function like well oiled machines. Ugh!
