I bought some Citrix for pre/post silver soldering clean to try but have not had much time to play. I noticed the small quantity solution I mixed in a paper cup & forgot about evaporated over time & went back to kind of crystal mush. Do you keep yours in a sealed jar or something & re-use it? Do you find you have to do all that pre-heat business to get lots of it concentrated in solution?

Ah I mix it ( Citric acid) up from dry crystals and throw it in a plastic 8 litre or so tub. Maybe make a litre or so. Nothing fancy just mix it with warm water and it dissolves readily. Typically it lasts one project and after that it’s really dirty and I just chuck it out.
