This is true. WD-40 really leaves behind residue that attracts crud... I used to use it for everything. Not I only use it to clean armor. Great with a green scrubbie for removing rust.
On sewing machines I ONLY use Tri-Flow as a lubricant.
As to bolt freeing, I start with Kroil (NOT an lubricant, it is WD-40 on steroids without the residue) It is actually referred to in its litrature as "the oil that creeps" If that does not work I spray some PB-Blaster into a cup and then apply it with q-tips. This is available at most auto parts stores. I learned about it when I owned two 1966 barracuda's... old rusty outdoor bolts.... The last level is a heat gun (hair dryer is better) I have not had that fail yet.
