Initial weights were taken for three paint cans. Yellow acrylic topcoat paint was poured into each can and swirled around to sufficiently coat the walls of the can. Any excess paint was poured back into the original can. The paint was allowed to dry for approximately twenty minutes before the cans were weighed again for a contaminated weight. Three hundred milliliters of solvent were poured into the paint can and scrubbed using a brush for fifteen minutes. When the cleaner was saturated, it was poured out and a fresh two hundred milliliters of cleaner was added and continued to be scrubbed for the remaining time. The paint cans were allowed to dry for twenty minutes before obtaining final weights.
