I'd like to sand my deck, put in many years ago by someone else, so
that I can stain it. Currently there are a couple of layers of paint
peeling in many spots. I tried to use sodium hydroxide, but that
didn't work well. I also tried a pressure washer and quickly learned
that I would end up with a fuzzy deck.
I believe that sanding is my best option.
However, I'm not sure what kind of wood it is made from. I believe it
is cedar, but wouldn't want to sand it if it is made from pressure
treated wood which can contain arsenic.
Can someone please help me to identify the wood? It should be obvious
for anyone who knows wood from the pictures I took showing the grain:
