Worked for a boss back in the 70s who would only buy Izal for the office. Said he couldn't stand the soft stuff sticking to his Yabbie. Haven't seen it in years but as Tony says, it made great tracing paper.
The simple trick with scratchy old Izal was to scrunch it up tightly, rub it between your hands, then unfold it before using it. Voila! No longer scratchy! Its other advantage was that it was 'gas-proof'. This meant that bacteria couldn't pass through it onto your hands, so it was considered healthier than soft tissue - which can let those bugs through.
Sure we do, Traci. But remember that Izal was invented in the days of tenements and terrace houses with outside loos that lacked hand-washing facilities.
He was right. There isn't a good toilet paper sold. Soft stuff have one set of problems, the hard stuff a different set. Maybe next millenium they'll have worked out a better method of cleaning because it's clear it's too difficult for experts to work out at the moment.
