White scummy skin a few days after primary racking

2 weeks ago I racked 5 gallons and after 5 days a white skin appeared on the top. I asked the local brew store and was told it was caused by a benign yeast. It wouldn't affect the taste, but was near impossible to get rid of. I cleaned the carboy, racking cane and tube as well as I could BUT!! The last batch I racked on saturday has just developed the same white scum on top. Do I have to throw the carboy or does anyone know how I can stop the rot?

Any answers greatfull received

What are you using to sanitize that carboy? Also, how does the beer taste that has had the film on top?

I also posted this message in rec.crafts.brewing and got a few replies. I seems it is a benign wild yeast causing the problem floating around in my basement where I brew. this is my answer to them.

I racked a batch last sunday in the same sterilized carboy I had the problem with, and wednesday the white skin was back on top.

I will be sterilising all my equipment for the next few days and hope that will be the last I see of the white scum. BTW even though it's only a week in the keg the beer doesn't seem to taste bad. It can only get better with age

thanks again
