Just moved here in January. It is time to power wash our home, something that doesn't happen much in 0% humidity Kansas. I never power washed anything in my life. So, my question is, should I buy a power washer and do it myself or hire it done? There are glowing reviews of services that do this for you. While I'm at it, I have read nice reviews of an electric power washer that is economical vs. gas which have more power. I'd prefer to not mess with gas power but if electric is not good, I'd love to hear input. There are other applications I could see to owning a power washer and that interests me. I don't know the chemicals used to wash either, but assume I can read about and purchase grass and environment friendly products. Thanks in advance for advice.
