I will give them a good wash this evening whilst I am soaking away the daily grime - I'll let you know the outcome, and thanks everyone for all the tips and advice.
I am pleased to say that I have managed to get 2 out of the 3 that no longer sprayed water to work again. I gave them a good soak overnight in warm water with added detergent and this morning they were used to spray my plants again. So thanks everyone for all the advice. I have now vowed to keep them cleaner from now on.
