One can assume that the least damage to the boards would be if you were to clean in the direction of the grain, by having a smooth finsh rather than a grooved finish makes all maintenace easier as there are no grooves for debris to get stuck into.
With regard to composite, there are so many and they probably differ according to the manufacturers instructions, for the better part refrain from using rock salt as the damage to the surface sometimes can’t be repaired, other than that I guess yu are right, a stiff broom it is…

A weather question! Do you have to ‘go with the grain’ whilst removing snow from hardwood decking and refrain from metal shovels? And what is the best way on composites-a large broom?
