you will find that problem with any and all copper removers. Copper is a component of brass so when the copper cleaner contacts your brass jag it dissolves some of the copper in it just like it does to copper fouling in your barrel, and causes you to get blue on your patches. In order to remedy this situation you need to get jags made of another material such as stainless steel, drelin, or some other not copper/brass material, that way you can see if you have truly removed all the copper in your barrel. Also, if you use a brass wire brush to apply the copper remover it will also cause the patch to turn blue, and brass cleaning rods or brass fittings on cleaning rods can cause the patches to be blue as well.
