We have had our composite deck for about 20 years. It's starting to show some wear on the main area where you walk. I hose it down every couple years with some mild soap and water.
Other that that, zero maintenance.

I did manage to break one of the solid steps last year, when I was running up the stairs and put my entire weight on one of the boards (2 boards per step)

Our neighbour seems to be sanding and trying to seal his wood deck every 2-3 years. I think it's pressure treated.

If it ever needs replacing, I will be using composite again.
