Hi all. Got a Naish, nice kit. The back wing needs to adjust but the two little screws are stuck. I wash in fresh water regularly and they had grease on them. Don't want to force screws too much at moment.
is boiling water a help?
WD40?
Any suggestions please. Pete
I tried looking back to see if another thread had answers, link to that if you know where abouts.

vinegar / WD40 are options.

just washing in fresh water won't do the job. You have to dry them out as well.

Grease no
Tefgel yes

In the past I have had success freeing small fasteners by heating them with the tip of a soldering iron. Heat them, up let them cool. See if it breaks the stuckness.

Had the same with the Naish. Used the plumbers blow torch. Heat it gently, don't hold flame over the aluminum too long... quick passes.

The aluminum heats up quick, wait till it cools a bit and the screw will release.

I have used easy outs a few times
you can buy a set or in single sizes

Were you using marine specific grease? Were you rinsing with everything disassembled?

Seconding RAL INN on the tefgel. I believe I do remember someone posting a video from perhaps the national distributor on the proper application a month back or so.

Success!
Boiling hot water worked. Didn't have soldering iron.
Will sort out some marine grease.

I don't trust just grease, get the gunk for stopping dissimilar metals causing galvanic corrosion. Treff gel i think its called Whitworths stock it its not like grease which is still conductive which is why you get the corrosion.

This is another option. Industrial quality
