Just a tip for other 3D Printer users. I like to make sure my print bed is clean before each print. I normally use some Acetone or Isopropyl-Alcoho.
I used to just use normal bottle and take the lid off and dab some on a piece of paper towel. Not a big deal.
A few months ago I came across these Windex Touch Up dispensers and removed the cleaner they came with and replaced with cleaners of my choice.
I was a bit worried that the Acetone would eat through the dispenser, but after a few weeks it's holding strong.
This makes it so much easier get a quick dab of the cleaner on a towel and give your print bed a quick cleaning.
I also do some TIG welding and it's also great for cleaning up your aluminum prior to welding.
One side note is these will normally leave a small quantity (I'm guessing 1/10 of an oz or so) in the tube that will evaporate. If you're in a very confined area this may be a concern. But, even using these chemicals in a confined area can be an issue. Make sure you use proper safety procedures with the storage and usages of these items.
Here is a quick video showing the dispenser in action.
