Cleaning Paint Rollers

What happens here

The presenter introduces the 6-in-1 scraper as his number three tool on the list. He holds up the tool, which has a multi-edged metal blade and a comfortable handle. He then takes a used paint roller, which appears to be made of foam, and demonstrates how the specialized curved edge of the 6-in-1 scraper can be used to efficiently clean off excess paint from the roller sleeve. He inserts the curved part of the scraper into the roller and pulls, effectively removing paint.
