Whats the best way to remove tree sap, paint, grease and grime from my spa cover?
Tree sap can be removed carefully with the use of lighter fluid. You should use it sparingly, then buff with saddle soap or Hot Spring FreshWater Cover Shield conditioner, immediately afterwards, then wipe dry. Do not use charcoal lighter fluid! Paint cannot be removed once dry, as solvents used to remove paint will damage the vinyl. Grease and grime may be removed with a thorough washing using a mild liquid dishwashing soap, and water.
