Re: Emergen-C ( the crikets are chirping on this one)
- Thanks Harry,
Thats what I wanted to know. I didn't buy the stuff specifically for
this hobby. But when I read the ingredients alot of them sounded like
the stuff in the homemade turbo recipe. Some folks have difficulty
getting some of the ingredients necessary from home brew shops or off
the internet and if I see something that looks practical and is
readily available I will throw it out there. I will however try a
small wash with it now to see if it helps or hinders. Thanks again.
