I stand ready to be corrected. Humbly.
I think that outside of physical contact abuse, (abrasion, puncture, acid etc), raft material is degraded most by ultraviolet light. The strategy of a white material reflecting more of the visible light spectrum does not apply to direct ultraviolet exposure, (different wavelengths).
The heating of the fabric could be a whole new ball game.
It's even possible that your raft material could be weakened more by regular cleaning.
