The bow maker should provide instructions, but in general it’s pretty straightforward: Wipe the bow with a soft cloth after each use, particularly if the bow is damp. Keep the bow somewhere dry and out of direct sunlight. Unstring the bow when not in use so it’s not under constant tension. Put the bow on a bow rack or shelf. Don’t leave it standing in a corner where its own weight will cause compression. Wax the bowstring every few weeks if the bow is in regular use.
