Ballistol Universal Oil can be left in the barrel for protection while storing BUT not this Robla cleaner, this is some strong stuff.
It needs to be removed from the barrel after cleaning.
This I can confirm. I spilled some on a steel plate that was on the bench being marked out to be made into a quick release plate for a new press. The markings were scribed in and after a couple of days when I came back to the job they had been pretty much etched away where the liquid had sat. You definitely want to clean it out thoroughly before putting a rifle away.

Geees boet :o :o :o Big eyes I got, I have been leaving it in for few minutes while packing away, then nylon brush and then wiping out with a dry cloth. The dry cloth thing is rather thorough as I shoot without wiping barrels out, hence my dislike of oiling barrels. I believed I had a coating left, but no wet residue.
Fok :o :o , I should perhaps start reading instruction once in a while again.
Now I am worried, very !!!!!!!!!!!!!!!!!!!!, have not oiled a barrel that's in use for ages, just left a Ballistol or M98 coating in barrel.
I now hope my bottle is not this stuff, had it for ages, smells nice ?
