I cleaned the top 5 feet or so from the catwalk, I used my 30ft yellow noodle for the upper portion, and normal wand for the lower. I am glad I didn't throw away that yellow noodle, but I never thought I would actually use it again!!)
Jim, I actually used nothing other than cold water and 2000 psi tip so I wouldnt damage the fine mesh. Owner did not want any chems period on the dryer. There is alot of electronic computer controls etc.. housed on that unit. I do think it would have came out even better with the chems, but these guys are huge farmers in the area and I respect their wishes on this one.
