What do u recommend to clean iPad screen

I agree with recommendation to use microfiber cloth. I've used the E-cloth product on my iPhone for years and now have started using it on my new iPad. They're very durable, don't scratch the screen or finish, and work really great. They're cheaper at the company website than on Amazon:

Never use chemicals on your iPad or any electronic devices, the chemical will strip away the protective coating and will ultimately damage your screen. Instead use a microfiber cleaning cloth like the ones sold at www.kbcloth.info and slightly wet it and wipe your iPad screen clean. Make sure that the cloth is only damp and not wet. This is the best way to clean your iPad.
