we visited a house for sale up north in the Montreal Quebec Canada area it has spruce vertical exterior siding that is black and gray. can this be cleaned and stained afterwards. Love the house,it was built in 2004, but I am afraid of the cost of upkeep etc.. can you give me some info on this. Thank you

Yes, you should be able to clean it by corn cob blasting. Plan on $1.50 per square foot of living space per year for professional maintenance after it is back in good shape.
