This has a round-about sort of solution, but bear with me.

When I first had my tongue pierced, I had to keep it clean etc and still retain a semblance of normal life (work, outings, etc) so to keep bacterial levels low, I was told to rinse well with water after eating (when I couldn't brush) and I carried a small bottle of biotene with me (the bottle was coincidentally an empty travel-size bottle of some other mouthwash, but still very effective) Biotene uses enzymes instead of alcohol for its antibacterial action, so it won't burn and can be used as often as needed, contains xylitol to prevent plaque buildup, and tends to be helpful in preventing dry-mouth (always a problem when I'm biking, no matter how much I drink)

hth!
