Well, I've never done this and I don't know if it is easier but my sister and her husband took the boards up on their deck, flipped them over then restrained them. Stripping seems like a lot of work and messy.
You could get a stripper take off with a scrub brush then hose off
I just did this actually and there was nothing speedy about it, unfortunately. Don't use a pressure washer as you can too easily damage the wood. You can see what I did here: https://www.flippingtheflip.com/2018/08/the-deck-redux-part-i.html
