    Would this be a bad idea to do, I used to do it the odd time when I worked in for Texaco years ago. I 'd like to give my own a blast now. Any suggestions?

    Modern car electronics do not like power washers. Be very careful if you decide to do it - protect any electronic components with well-sealed plastic bags, and do not direct the spray at any electrical components.

    Personally, I wouldn't do it. Get some Gunk, brush it well onto/into the manky areas, leave for 30 minutes, then rinse it off with a regular garden hose. I'd still seal / avoid the electronics if doing this.

    It's fine. There are lots of vids on youtube showing it. Cover the alternator with plastic, spray some WD40 on electrical connections.

    Use moderate pressure and don't point straight at electrical areas. Use some degreaser. I also like to finish the plastic and rubber surfaces with a synthetic cleaner so they come up shiny.

    I agree 100%

    I wouldn't agree with this, for a start there is no need for a power washer in conjunction with the degreaser, the degreaser will do the work :)

    Well the power washer is just for rinsing it off after the degreaser does it's job.
