Only onve valve to drain air tanks?

i think thise valves are replaceable.

i'd at least spray them up heavily with something like PB Blaster.

of course, you may want to have new valves on hand as well. i'd then open up the new valves, and coat the threads with something like Permatex anti-seize. just DO NOT get that stuff on you or your clothing, it'll never come off!!

also sold at nearly any auto parts store.

 

You can take a hammer and tap them open enough to bleed off then shut them. They are brass fittings and will be just fine if you tap them counterclockwise to get the started.

 

Wow, you say thank you and then call'em all Good Buddies. Lmao.

 

Yeah, if you just use the normal wash soap. Rub goop hand soap on it, let it sit for 30 min then toss in wash with a handful of the goop with your regular soap. It will come right out, and the goop will not hurt anything. It actually states on the container "safe for laundry". I been using this stuff in my laundry for 20 years. Once you dry it, its set, won't come out.

 

i usually use Lestoil to remove oils, grease from clothing. never heard of goop being for clothes though.
