I just received the Chicago Electric 1800 PSI pressure washer I
purchased from Harbor Freight. After reading the manual I learn it
can only handle mild detergents. Is that normal?

I bought it to clean my house siding. My understanding is that
strong chlorine based detergents are normally used for that task.
Was I ripped off? How would I know which pressure washers can use
the normal house cleaning chemicals?
