Noise in Glass

[Newbie82]

Hello! I really need help again. The following image is a render result I receive. The problems are the noisy parts in the glass body. Could anybody help me to get rid of them?

It's a problem with the model being rubbish! Your polygon layout has to be really clean to get nice reflections and refractions on curved surfaces, and the glass needs to have thickness too!
