For years I happily wiped my rifles down with a rag (read: old t-shirt) with a little Rem Oil to prevent rust etc. This weekend, after hunting, I noticed everyone in my hunting party used silicone impregnated cloths. No mention was made of one being superior to the other, but it has me confused about my choice. Is there a reason I should be using a silicone cloth instead of my faithful Rem Oil? Does it last longer or provide better protection?
