replacing oil screen gauze

[Stuart Giles]

One question- what/ how do you clean the solder and flux residue to neutralise the flux and stop corrosion?

If you have a dishwasher and it's a SWMBO free zone at the time, putting it in the dishwasher is very effective; dry it as soon as the dishwasher is finished to stop rust forming on the frame.

I find that a nice big copper iron heated with a propane torch or such  is the best thing for a job like this. This flux works really well on steel as well as stainless https://www.solderconnection.com/P584/A8...-Flux.html This flux is really aggressive so needs washing off straightaway after soldering.
