There is a difference between all Scent Elimination cloths...take for instance...Reactivating them

Scentblocker- Dry it
X-System - They say you don't need to but might as well wash it
No Trace- Wet it.....wash it or put in in a creek then hang it up is what I've read.
Scent-Lok- sames as Scentblocker

well thats all the time I have right now to mention some Diff.!
