I've been using this Wipe Out stuff but this applies to anything like Hoppes 9 or anything really as I've used it a very little. Anyway, how much should you use? I've been getting the whole patch wet and running it through. Then doing a dry patch. My 30-06 even if you only shoot it 15 or 20 times takes forever to get completely clean. I mean over and over and over. I've used a ton of patches and it seems like I'm emptying the the bottle. During cleaning 3 guns it's not uncommon for me to use more than half the bottle. It gets it clean but it uses a lot of patches and a lot of the cleaning solution. I'd guess it's about a 12oz bottle but it doesn't say so I'm not sure. Might be 9oz or so. Not sure. Anyway, when I went back to get more after a month or two the guy acted like I was crazy for needing more. I'd used 2 bottles at that time. He acts like I shouldn't be using much at all. Am I using too much? I figure the whole patch needs to be wet or does it only need to be a drop? If it's a drop it seems like part of the patch running through the barrel would just be dry. I'm doing this over and over again. Sometimes I will do it several times in a row or sometimes I will do it then run a dry patch then this then a dry patch like that. Towards getting it fairly clean I run one of these then a dry patch over and over until both are spotless. I've got them to where they barely have any black on them but being the perfectionist I am I usually keep going until it's completely clean.
