Yep...Lemon Pledge renews the finish and puts a protective layer of wax down. Simple and effective....oh, and also recommended by Georgina Terry.
When I travel with the bike, I carry Pledge Wipes as a simple clean up.
End of season, the bike gets a paste wax shine in her annual "spa treatment" at the bike shop. This seals and protects the finish.
