Thank you for posting this video, I just had a party saturday and it was hard and slower, the paper plate and spraying different colors on the sponge will make it easier.
You have choices: 1) don't clean them. They have lots of pigment on them, just re-activate. 2) swish in 91% alcohol 3) rub liquid soap into bristles and rinse after.
