As with any seized bolt, if you want to remove it easily, hammer it in gently before unscrewing. The external side of the bolt's threading is the part that has been pressed against the solid outer thread. The opposing (Deeper) side is the side gummed up with the tar of a billion coffees. Put your best-fit screwdriver tip into the bolt, and hammer it firmly but not insanely to separate it from the seized state it is in. This doesn't need a sticky. This is common sense. Hold the screw driver by the plastic end. The metal pointy end goes in the fastener. More importantly: Don't tighten that bolt too tightly. For god's sake, people! That's a stainless steel fastener going into the bottom of a brass boiler! What do you think is going to happen after you over tighten that damn thing a dozen times? It ain't gonna be the 30 cent bolt that strips, it'll be your $300+ boiler. What are you thinking? "Oh, I should tighten it as tight as I can because if it ever loosens my house will fall over"? Take it easy. If it loosens you'll get weird channeling and you'll find and tighten it. Three foot pounds is plenty. It's a metric 6 at best. It's in a brass thread. Settle down.

I suspect you'll find, Mr Canadian correspondent, that very few of the people having trouble with getting the showerscreen off the showerhead committed the crime of which you accuse 'em. As I believe I said (or at least I hope I did!), most of us have been able to do this cleaning job without problem for quite a while, before finding that the screw won't come out. Well, not with any degree of ease. This would mean, doncha think?, that we are aware of the need NOT to tighten the screw overmuch; for had we been doing so, we would've found the problem 'way back. :-| No: it's not a matter of our being total dimwits and needing to be told by some that the screwdriver is held by the plastic end, etc., etc. By all the gods, you're a fairly stroppy bloke, aren't yer?! Take it easy ...
