Auroflux - lost its colour!

[Siskin]

I've had a bottle of Auroflux for about a year, and initially found it to be very good for silver and gold soldering.
However, recently, it seems to have lost its yellow colour in the bottle, and is now almost colourless! It's also lost its effectiveness as a flux. A great shame, as the bottle is still nearly full.

Has anyone else experienced this?

I think someone asked about colour loss a while back but it didn’t make any difference to it’s efficiency. Mine is a much more than a year old and seems to work the same. Maybe just give it another try making sure that everything else is clean and as it should be

I have some from 6 odd years ago, Its gone clear too, just give it a proper good shake before you use it, mines fine still.

I shall give it a good shake, and try again!
Thanks both!
