Yes use the Gyeon Iron-x as a clay lube
but only with the Gyeon clay! Other clays will fall apart.
2 steps become 1 and no need to buy an additional lube.
I spray the iron product on, probably a little more liberally than its needed, it does its thing and turns the contamination purple and I give it a little time to work and then I start with the clay.
As well as acting as a lube for the clay it also shows where contamination still remains. Something thats not always easy when you clay. But now it will continue turning purple.
I couldn't believe how much I must have been missing previuosly as I'd always gone on feel alone (pretty much the only way there is when using clay) but now I can identify areas that require a little more attention
Been doing it that way for a while now. Actually just ordered new Gyeon clay last week.
