Hi enfield2band
Re Fairy Liquid that’s a point, I hadn't considered added salts.

I changed from Tesco's own after one of the guy at the club mentioned about somebody losing the blueing off of their re-blued pistol which was left to soak in a strong washing up detergent. I was recommended to use Fairy and have done ever since, I cant say I have noticed any problems with it but after a washing out I have followed the advice I was given to really flush out the detergent then de-water using WD40 before oiling, but I will look into it.


Cheers
