What about using brake parts cleaner on the liners. Im refering to the stuff in an arasol can..

[zubzub]

Can't remember which, but brake part cleaner is either acetone or ether.  Just can't remember what it tastes like right now...it's been awhile.

So while we're on the subject more or less, is it necessary to actually drain the air tanks, or just let enough air out until it stops spitting?

[buswarrior]

If there is sludge in the tank, the high pressure air rushes past, in a way, holding the sludge back from the drain.

In order to be better acquainted with your coach, empty the tanks completely, and leave the drains open overnight. Place a clean rag or paper towel under the drains and see what gloops out overnight.

In those many hundreds of thousands of miles put on that coach, there will have been some accumulation, so a simple clean out may reset the cleanliness clock and you'll never see anything but moisture again in your life time.

Nothing comes out? job is done.

Something? time to determine is it is left over from some past deterioration or is current. Is it black or more brown, thick or thinner? Accumulated over tens of thousands of miles or since last Tuesday?

Clean it out with the spray of your choice shoved up into the drain and let 'er rip. removing the drain assembly will make it easier. depending on what you have, lead or follow with the garden hose. No need to use expensive cans of stuff for larger more willing volumes of oily crud.

Then button it up and run the coach for some mileage and see what happens.

oily sludge harbors moisture, and you may recall the troubles on here those short few weeks ago of frozen busnuts...a clean air system is a reliable air system. moisture in there anywhere is humidity and will frost in the worst of places.

happy coaching!
