Cleaning bore before patterning

[Cutt]

Has anyone ever heard of running a swab with windex on it,  through the bore after cleaning to remove any remaining oils?

Never heard of this, but did read it somewhere and thought it could be corrosive on some metals, but then again I thought Hoppe's 9 was ammonia based?

Rubbing alcohol is the only things I've heard to use or maybe some mineral spirts

Denatured Alcohol most rubbing Alcohol will not do as good.   Big thing is get the oil and other junk out the barrel.
