| 7/23/2017 8:43 pm 750 spray wash cabinet by Engine builder - verified purchaser Washer works great , I have put 6 cylinder international diesel heads in it , several sets of V-8 heads and blocks. The only downside is the soap that comes with it. I could not get it to stop foaming over with the 3% soap solution per directions on the container and turning thermostat all the way up to 175 degrees (max setting) , even with ordering defoamer and using it. I had to change out the 53 gallons of solution with different soap. Now problem is gone.
