Yes just the simple isopropyl 91% alcohol. Car windshield washer fluid is cheap too. As for other cleaners, as long as lead, copper, and plastic fowling is not an issue, simple water will clean up Triple Se7en. I use a product called Simple Green that I mix with water and it really cleans the fowling.

If I have stubborn fowling then I use Birchwood Casey #77 solvent. Other wise a lot of the home cleaners, will clean the barrel fine. Just be careful with the cleaners on wood stocks...
