In terms of wet cleaning fluids, the most popular sensor cleaning fluid is probably Eclipse made by Photographic Solutions. It is a very pure form of denatured methanol with almost zero impurities. Many types of alcohol used as solvent or cleaners contain impurities that can leave behind residue when they dry. These impurities will leave spots on the front of your sensor (or, more specifically, the front of the stack of filters directly in front of your camera's sensor¹). So using alcohol marketed as a household cleaner probably isn't a good bet, either.
Just bite the bullet and spend $20-30 on a sensor cleaning kit that includes 2-3 swabs and a small bottle of cleaning fluid designed specifically to clean your camera's sensor. Or buy swabs and fluid in bulk and save a little in the long run. That will go a long way towards reducing the chances of damaging your camera's sensor by cleaning it.
¹ Even cameras without low pass anti-aliasing filters, such as the OM-D E-M10 still have a glass cover in front of the sensor in the form of the infrared cut filter. Many also have glass plates where the two plates that make up the horizontal and vertical low pass filters would be. Some, such as the Nikon D800E and D810, even have dual horizontal low pass filters that offset one another.
