Take good care of your swing set and it could last a very long time! Round pole swings require little maintenance due to their natural properties. Use a soft brush to remove dirt from the set, and wipe metal parts and swing seats and slides with a damp cloth and light detergent. The wood on the swing set was pressure treated with a chemical on production to inhibit rot and infestation. At the end of each season, treat the swing set with a water based stain for use on children’s play equipment to ensure longevity.
