I just used distilled vinegar and a drop of dish detergent.
Combine a cup of the vinegar and a small squirt of dish detergent into a spray bottle and shake it up. Spray onto a microfiber rag (or any sponge but the microfiber ones don't scratch) and wipe down your appliance's going in the direction of the grain. I didn't realize it mattered which way you wipe but sure enough it does!
Look at all of those water streaks!
Streaks are gone and they are shining like crazy!
For tougher jobs with stainless steel pots and pans switch out the dish detergent for baking soda. It really does the trick! I went a little crazy cleaning everythingggg in the kitchen.. (refrigerator handles, sink, toaster, dish washer, etc).
