Osmo Wood Reviver Gel (6609) is a specialist cleaning and restoration gel designed to revive weathered, greyed, or dirty exterior timber surfaces before re-oiling or re-finishing. It removes grey discolouration, algae, mould, and surface dirt, restoring the timber to a clean, open-grained surface that is ready to accept a fresh coat of Osmo exterior oil or finish.

The gel formula clings to vertical surfaces and decking boards, allowing it to work effectively without running off. Suitable for use on all exterior timber species including hardwood decking, cladding, garden furniture, and fences.
