How to clean the filters?
Cleaning the Filter-it is very simple: use pipe cleaners, like the one included in the package, find them in all tobacconists or dedicated shops, pass it several times inside and it will be ready for the next use.
Alternatively you can use any type of card: napkins, handkerchiefs, etc.
Cut a string of the right size, roll it up and pass it inside the filter as the brush for an optimal result.
For deep cleaning you have 2 different solutions:
1) in a saucepan add water and milk (50/50), insert the filter and let it boil, all for about ten minutes then rinse thoroughly.
Wait a couple of minutes for the filter to dry and you can start using it again.
2) immerse the filter in pure alcohol, you can use the package or any other container, shake everything gently for a couple of minutes then rinse as above.
