Silverflo 55 Flux

[Malcolm HarveyParticipant @malcolmharvey97633]

I was just wondering if Silverflo 55 flux has a shelf life. I have a plastic tub of the stuff still in powder form. It is at least 20 years old. Sorry if I have given it an incorrect title but that is what is written on the tub with a felt tip pen!

Hi Malcolm.

I asked this a couple of weeks back and was told that it doesn’t go off, even though it does dry out. It can be re-mixed and the process is easier if you add a drop of detergent when you first mix it.

Thanks. It will probably do for me to learn about how to silver solder if nothing else!
