Osmo Wood Reviver Gel (6609D) is a specialist cleaning and restoration gel designed to revive weathered, greyed, or dirty exterior timber surfaces before re-oiling or re-finishing. The 2.5L size is the trade buy for larger decking areas, cladding projects, and garden furniture restoration. It removes grey discolouration, algae, mould, and surface dirt, restoring the timber to a clean, open-grained surface 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.
