Noise on render, cant get rid of (picture included)

I am rendering out a vending machine and the interior part, where a soda would come out, is rendering with all kinds of noise. I have attached a picture showing the noise. In the pic it just looks like the inside is rough textured, but when rendered in a movie its like TV static. Can anyone tell me how to get rid of this. I am a C4D amateur at the moment and any help would be appreciated. I have tried adding more light but that did not work.
