How to clean intestine for longganisa/sausage casings, the easiest way?

Описание: In the first few months of making longganisa, I got a hard time cleaning the hog intestines. I told the way i cleaned to a friend, Julita, and she taught me how to do it without spending too much time. I found it really effective and I want to share it with you kabayans, especially if you are planning to open a home made meat shop.
