How do you clean a used rubber float grout TOOL?

To clean a used rubber float grout tool, first, scrape off any excess grout using a putty knife or a similar tool. Then, rinse the float under warm water to loosen any remaining grout. You can use a sponge or cloth with mild soap to gently scrub the surface, ensuring all debris is removed. Finally, rinse thoroughly and allow the float to air dry before storing it.
