i have a supply of TCP in my room to just dab on with some cotton wool.
But i'm not sure if you can get tcp where you are...
there should be other anitceptic gels or lotions on the market.

thats the link for TCP anticeptic.
Otherwise, keep it covered and clean.
Hope i helped and get it sorted soon :)
