They recommend cleaning the glass mat with regular alcohol and hand sanitizer for stickier messes.
It's also a good idea to clean it once in a while with some Expo Dry Erase Surface Cleaner, after you've degunked it with regular cleaning. Yes, it has alcohol in it to clean but it also has a conditioner in it to help the protect the glass. Over time, white boards can get dried out with over use. I used to have one in my classroom that could only be cleaned with a Comet style bathroom cleaner. Not good.
They also have other Expo Whiteboard Care like a 3 step process for white boards if you really want to pamper your glass mat.
Try it once and you'll be sure to notice the difference.
Other than watercolor, which I hardly ever use, my brushes get pretty grungy. I'm not the greatest at taking care of my brushes so when I have to clean them- I really have to clean them.
I found a silicone oven grip at a yard sale last year that I've been using to clean my brushes (works great for makeup brushes too). It's just soft enough, yet textured enough that I can really scrub my brushes against.
It's reusable, easy to clean and dries quickly.
Use a mild dish soap or even a facial cleanser for your brushes. If your bristles get too dry, scrub them in some hair conditioner to retain softness.
The textured grips also make great stamping platforms (:
You can also refill your other pens as long as you refill it with the same type of ink in there. If you don't know, Google it. I refill my regular permanent Sharpies with black dye ink and alcohol and haven't had to replace near as many as I used to.
To refill, simply pull the nib off the pen gently with a pair of pliers. Some pens you may have to pull the bottom off to refill and some pens you just can't pull anything off. Sorry.
Once you've exposed the barrel, place a few (2-5 drops depending on how dry your pen is) into the barrel and then replace the nib. Store the pen upright so the ink can fully drain into the barrel.
*There may be a splurge of ink coming out the nib the first few times you use it afterwards, so be careful!
