Just don't get boiling water all over yourself when trying to clean cartos. In fact, I'm sure she'd say, don't boil cartos at all, just use new.
yup....hate having 1 good arm and hand now!!! getting good at it now I think..yes, NEVER BOIL CARTO`S...BUY NEW ONES... when you dump boiling water all over your hand and arm, it causes blisters , 2nd degree burns and shock...
