I am hoping someone on this forum might be able to give me some advice on pressure washers. We would like to purchase an electric pressure washer to clean our porch (teak) which unfortunately is a favorite place for our chickens to hang out. We'd also probably want to use it to clean our painted wood siding and windows, and maybe even the cars. I am sure we'd also find tons of other uses! But I am somewhat overwhelmed by the choices, and am afraid of getting oversold when I go into the store. So I'd really appreciate any advice on what PSI to look for, and also if there are any brands that are particularly good or particularly unreliable. Although I don't want to break the bank, I'd rather buy a good one the first time.

Thanks very much in advance for any advice at all!
