Guarenteed method to prevent spoilage!

[Zxlork]

Although i'm super new to distilling (doing 1st strip run as I type this) I am very interested in doing whiskey and a lot of grain mashes later on as well as rum. That being said I see that it seems quite often at least people posting have problems with their ferment getting spoiled by an invader. I however have been doing homemade wine for the past 4 years. Why do I not see more people using Campden Tablets? They are super cheap only take 1 per gallon and guarantee no infection in your batches. Just do your mash or whatnot once everything is mixed throw in the right amount of campden tablets come back 24 hours later pitch your yeast in a clean and sterile environment. I'm not sure how much bacteria is on corn or rye but I know this is a very important step in wine making for fruit because they are loaded with bad bacteria.
