Alternatively, you can use a garden hose to rinse any remaining residue from the roller cover. Put the roller on a pole and spray the roller with a hose until the paint starts spinning off. If you run the hose over the entire roller, the paint will be sucked out with the force of the spinning. Then put the stream of water on the very edge of the roller and let it spin fast to leave the roller almost dry, because the water will also spin out. [2] X Research source

When you fill these trays, you should pour in enough fluid to cover an entire roller cover and cage.

By preserving your rollers, you can avoid the hassle of cleaning. This is a good option for when you are completing a multi-day project.
