Fibreglass is a composite material made of glass fibres in polymer resin mix. Uses of fibreglass include surfboards, kayaks, automobiles and boats. Decals and stickers are often applied to the surface of such fibreglass surfaces to add decoration and personalisation. Stickers and decals leave behind a sticky glue-like adhesive when removed. Use common household solvents to remove glue and adhesives from fibreglass.
Apply a small amount of acetone solvent (nail polish remover) to a clean cloth. The cloth should be damp, but not soaked.
Wipe away the glue on the fibreglass using the moistened cloth. The solvent causes the glue to soften, making it easier to wipe up and remove.
Reapply acetone to the cloth and continue to wipe the glue away until it is completely removed.
Mix a few drops of liquid dishwashing soap in a bucket of water.
Moisten a cloth with soapy water and wipe down the fibreglass to remove any dirt.
Dry the area with a clean cloth.
Test a small area of the fibreglass with the acetone solvent to ensure no damage is done to the material.
Do not use a razor blade to remove glue on fibreglass. Razors may cause deep and permanent scratches in the fibreglass.
