glass carbouy help

[stee41]

Hi all,

I have a 6 gall glass carboy, it is not stained but I cant get some marks off the inside, what are the best chemicals to use to clean this thoroughly? I have tried double strength cleanser and even bleach but cant get it clean enough, it looks like tiny deposits of cleansing powder stuck to the inside of the glass, a brush wont move it either!!

cheers all

Have you tried a percarbonate cleaner? That is what I always use on my glass carboys and I have never had an issue and only rarely need the use of the brush.

Cheers
