I find the Phase solution, spatula and wipes work great. But so dies Eclipse 2. You got two bottles of official Phase cleaner with your back. B is for regular cleaning and IME works like Eclipse -- meaning very well -- and a pass with B or Eclipse is usually all I need for even the most stubborn crud. Next, A is for really bad crud that won't come off with B, and is messy, requiring a scrub with B to get it off! The plastic spatula and special wipes work great too IME. The wipes do look like PecPad wipes, and solution 1 appears to be similar if not identical to Eclipse. Anyway, fold a wipe in half and wrap it over the spatula, wet with a few drops of solution B and wipe across the sensor. I repeat with a fresh wipe and only one wipe and find that seems to eliminate any streaks. (Note that the edge of the sensor cover glass metal clamp can snag wipe fibers -- plastic electronic tweezers can get those.) I follow up with a gentle pass from a BRAND NEW microfiber lenscloth, but this is not a supported step, so use at your own risk. I find that last micro-fiber pass removes any minor streaks solution A or Eclipse might leave.
If B doesn't get your blobs, then start with solution A. This is a blue, soapy kind of cleaner and will definitely leave streaks, but they will clean up when you repeat with solution B -- just make sure you don't let A dry, get it with B while it's still wet! I would use plain de-ionized (or distilled) water on a pad before solution B, reserving B for only crap that water, Eclipse or solution A won't get. I find that DI water removes a lot of crud Eclipse or regular alcohol-based cleaners won't, so keep a bottle around.
FWIW, I use DI water for getting salt spray off my lenses and exterior camera surfaces, then follow up with Eclipse to remove the water streaks from glass. Anyway, DI water is cheap and readily available in most grocery stores, and a great thing to have around for general cleaning of camera equipment.
Finally, I keep a handful of E-Wipes in my bag for emergencies. An E-Wipe is essentially a Pec pad pre-wetted with Eclipse and stored in a foil packet. These work great in a pinch. Note that they are so good, they pull the oils right out of your fingers and can transfer that to the surface you're cleaning leaving streaks, so I wash my hands first -- hand-sanitiser (mostly gelled alcohol) seems to work fine for that purpose.
