To safely dispose of paint, turn it into a solid by mixing it with kitty litter. Let the mixture dry out for one hour before throwing it away. If the gear is in good condition, consider donating it to your local recreation center. Or sell your items on a site like playitagainsports.com, which is dedicated to used sports equipment and fitness gear. One caveat: Check that gear like strollers and cribs don’t have any recalls and ditch older items that might not be up to modern safety standards.
