Abstract:
A system for cleaning baked on organic and inorganic residues from a surface, the system comprising:a first chamber which holds a first cleaning fluid; a second chamber which holds a second cleaning fluid; a first outlet in the first chamber for selectively withdrawing the first cleaning fluid from the first chamber, the first outlet being selectively connectable with a first fluid line for transporting the first cleaning fluid to the surface; an inlet in the first chamber selectively connectable with a second fluid line for selectively returning the first cleaning fluid to the first chamber after contacting the surface with the first cleaning fluid; an outlet in the second chamber for selectively withdrawing the second cleaning fluid from the second chamber, the second outlet being selectively connectable with the first fluid line for transporting the second cleaning fluid to the surface; an inlet in the second chamber selectively connectable with the second fluid line for selectively returning the second cleaning fluid to the second chamber after contacting the surface with the second cleaning fluid; a selectively openable member connecting the first and second chambers which is selectively openable to allow the first cleaning fluid to mix with the second cleaning fluid; and a means for selectively opening the selectively openable member.
