There are various methods of filtering signals of which the the matlab built in function filter should be good enough for cleaning up your signal. Read about filter in matlab. If that doesn't help, reply to this post.

Hey Ben, the images of your filtered signal look quite good from my point of view. When you recover a signal from noise, it is impossible to get the original signal back. You can only get an approximation of it; the reason is that part of the amplitude is either attenuated or magnified as a result of the noise. No need to doubt your work. If you don't mind, can you post the expression of your noisy signal, x(n) = signal + noise. I would like to test it to see if I can get similar result.
