We bought a power washer a couple of weeks ago and decided for some reason that today would be the day to try it out. We have a LOT of deck space and it's obvious it hasn't been cleaned in quite some time.
We ended up getting most of the decks cleaned when the power washer let out a really nasty sound and smoke starting spilling out of it. Needless to say we blew it up. On a good note though, it's still under warranty.
Here is our partly cleaned deck before the blow-up incident!
