Best practice for a blow-off tube is to just use some of your sanitizer in water. That keeps shit from growing in it, and since you have a blow-off and NOT an airlock, there is no risk of it being sucked back in.

If you don't have proper no-rinse sanitizer, mix a small bit of household bleach in there, typically not more than a small cap-full if you're just using a couple litres of water.


pic related, this is what an airlock is, it goes in the top of your fermenter/secondary in a stopper with a hole.

1) sorry no got rid of all my pictures to damn many (16,000 kept the backgrounds though)
2)when making alcohol you cant let any oxygen go into it this ruins any chance of getting alcohol, instead you'll have funny flavored something. Basically the guy was to cheap to purchase a air lock pic related

Airlocks are dirt cheap.

I know this is /DIY/ but air locks are really cheap. like less than 2 dollars. the real /DIY/ing should be the brewing.
