Hi GuysDennis, we used loads of TCE when I worked in the lab and yes washed our hands in it too!My father suffered with Parkinsons, very bravely but it's not nice !Looks like I better enjoy myself.CheersDougMine too! what a horrible disease it is Paraquat weedkiller has also been linked and many many other things. So i guess it will take a very long time for someone to 100% confirm that any substance is a cause for a disease....
