assalaamu alaykum,

I have read from a book that everything made of pig is napaak and you have to wash your hands if you touch it. However,in the past we have eaten many foods which are haraam unknowingly and sometimes we never used to wash our hands after. We used to touch all other things with the same napaak hands. My question is:

1) Does this make everything else napaak that we touched and we have to wash our hands if we touch it ( there are some things which we cannot wash because they will be damaged if we put them in water e.g. electronics items)? there are lots of things which we touched with napaak hands, isnt it too hard to purify all of these?

jazakallah
