Hi Mr. Simon, Your suggestions are good. I will look for some pipe cleaners today. What kind and size of can do you use.? I was always afraid of using WD-40 at the pressure bar because of travelling. I used liquid wrench instead but it is super messy and always the lid comes off the can and it pours it self out in my truck. Thanks for the tip. James Grebe R.P.T. of the P.T.G. St. Louis, MO.
