I've used a lot of bamboo skewers, which eventually have to be thrown away. I've been looking for reusable stirring stick options - something that won't absorb liquid resins, paint, or lacquer thinner. I decided not to use metal rods because they can scratch the cups I use, which are made of polypropylene, which resists every chemical I use. So I figured the stirring sticks should also be made of polypropylene, but finding such sticks has proven difficult, until I theorized maybe those cheap watercolor brushes are made of the same material. I bought a pack today, dunked one brush (the butt, not the bristles) into a cup of lacquer thinner for several minutes, swishing it around to make sure it was sufficiently soaked. Then I dug a fingernail into it to see if it was softening, or turning gummy, but it remained completely intact. Other common plastics like ABS and vinyl will be noticeably affected by lacquer thinner. But this showed no surface property changes whatsoever. That means I can clean paint, resin, and other residues off of it with lacquer thinner (it's what I use to clean my polypropylene mixing cups).
I'll be stirring paint, and small batches of resin with these from now on (hopefully).
30 brushes/stirring sticks for $1.
