I have a pressure washer which is failing - no pressure. I opened up
the pump to see it full of gunk. It appears to be made out of what
looks like galvanized aluminum. It also has some brass. What can I use
to thoroughly clean the gunk and mineral deposits?

Don't know how you can clean it out but I loaned my new pressure washer to a
friend along with the user manual. Told him to be sure to rinse it out
after using engine cleaning solution by running clear water through the
solution pickup tube. He didn't listen or read the instructions and when I
got it back a couple of months later, I fired it up and promptly cracked the
pump housing. It looked inside like you've described. Since then, with my
new one, I use no cleaning solutions. Just use it to spray pressurized
water and I've had no problem for years.

I never used mine with the cleaning solution siphon. Just hose water.
What is better, a brass manifold or aluminum?
