RE: TC 17 Bore Cleaner
First off welcome to the forum.
The 50/50 mix of isopropyl alcohol and car windshield washer fluid will work as a bore swab and help to clean the fowling from the barrel. It will not remove lead, copper, or plastic fowling. It also will not protect the barrel from rust after cleaning.
