Over time the handles for dumping the tanks have become harder to pull. For sure do not want to break those off !! What does everyone use to lube the handles with ? Thanks !! :h
I have drained the black tank and then pour a couple large bottles of veg oil and let it soak. Then I go outside and pull and push the handle several times quickly. This is best to be gone for a time for the best results like out to lunch.
