I reckon people don't get as dirty, no real manufacturin/heavy industry these days , and people wear ppe more, I grew up with having pots of the green stuff in the house due to my dad, i have a big 1kg tub under the sink but it will last me a good couple of years, Now a days there are a lot of other brands available, we got loads of loctite hand cleaner free from various reps at work etc.
I'm not nocking the brand or owt, just don't know how well received tee's would be
