Pressure Washing Guide

Is this kind of thing even possible? I know it's probably dangerous to use straight bleach in a pressure washer, but is there a bleach-like chemical that can be used with one?

No real reason, just curious.

With the most common chemical injection setup on most pressure washers, the chemicals are injected into the water stream after the pump. This is called down-streaming because the chemicals are introduced into the water stream on the downstream side of the pump. Because of this it is safe to use bleach and other chemicals with your pressure washer, it will not harm the water pump at all.

There is an upstream chemical injector which is self explanatory. In this case the chemicals do run through the pump so other precautions are necessary. This type of injector is pretty rare and does not come standard on most pressure washers.

Thanks, I was more or less worried about my own eyes and skin than the washer. I'll see how well this cleans up the side of the house, believe me, the grime would be grounds for a war declaration.

This is a legitimate concern, but I think the explanation above is right on. However, I must ask. What are you using bleach on? Sometimes in incidences where there is need for creative or significant cleaning, a professional can be used! I haven't had this situation yet, but if I did, I have heard the angie's list can be a resource. Have you thought about or tried this?

IMO, you have to be careful and ask the right questions when hiring any professional no matter what the ad source. But with that said, Angie's list and Craigslist have had a bad reputation in certain cases and most (not all) professionals steer clear of advertising on them.
