How interesting, and sad! There used to be someone active in this thread who lived in Florida. She collected rain water for her rehabs. I never gave a thought to why until now.sooo my red purse that has spots turning black on it - i think i’ve figured it out !
my hone has hard water - and i used unfiltered tap water to dunk my bag !!!
this is the info i found -
The constituents of hard water when it comes into contact with wet leather will react to the tannins in the leather and will eventually result in the leather turning black. The minerals contained in hard water can also cause the leather cleaner you use to clean your leather to build up soap residue.
anyone else run into this issue and figure it out the hard way like me ??
I guess the effects aren't reversible?
