angel, I most certainly suggest that you clean your iPod properly. If you do not, there will be a risk of corrosion failure at a later time. [guide|5825|Here is] a guide that will show you how to clean your iPod. It was written for an iPhone, but all the points still apply to the iPod as well. Use [http://www.ifixit.com/Device/iPod_Touch_2nd_Generation#guideList|these guides] to work on your iPod. Replace the battery after you cleaned your iPod. I am at a loss about the European supplier of original parts, but a Google search might help you with that. Hope this helps, good luck.
