Am using Windex with vinegar (this is the clear Windex) for guns firedwith Pyrodex and 777. Windex with vinegar also makes short work of breech plug cleaning. For guns fired withPinnacle i use water forthe bore and Windex with vinegar forthe breech plug. Pinnacle is much cleaner burning than Pyrodex and 777 andthe gun isvery easy to clean.
