YMMV, depending on how old your whiteboard is. I’ve noticed that on my own whiteboard, this process causes some colors of whiteboard markers (namely, red and dark blue) to smudge more than other colors. (This will take more time and paper towels than you think!)Īnd voila! A whiteboard that is clean and collects marker smudge much more slowly. If you draw a line with your finger on the board and you see a smudge, that is WD-40, and you need to keep drying. Keep drying until there is no excess WD-40 on the board. Then, dry the WD-40 off of your board using paper towels!

This will likely cause your room to smell, so I encourage you to open some windows before you do this step. Turns out that WD-40 really does fix everything. WD-40 “plugs” the microscopic holes in your whiteboard that caused stains - marker ink could get into the holes but then couldn’t be erased. Your goal is to make an even coat of WD-40 across the whole board. The paper towel will quickly become saturated with WD-40, but keep using the same paper towel to spread the coating this way, you pick up as little WD-40 with your paper towel as possible. Use a paper towel to spread the coating evenly across the entire whiteboard.
Spray your whiteboard generously with WD-40 using the spray nozzle ( not the tube.) I cover the edges of my whiteboard with painter’s tape to avoid spraying the wood finish. (Timestamp 0:13–0:17) Now, we need to “resurface” the whiteboard so that there are fewer stains in the future. In addition, make sure that your whiteboard is completely dry by using paper towels or washcloths before proceeding. You want to make your whiteboard as spotless as possible before the next step. (Timestamp 0:12–0:13) If you still see areas with any surface stains, repeat steps 2 and 3 on that area alone. Any bumpiness you feel is toothpaste left on the board from the previous step that you need to wipe off with alcohol. Repeat as necessary until the entire whiteboard feels smooth to the touch. Switch paper towels as it starts getting dry or as it fills up with stains. To fix both of these problems, put some isopropyl alcohol on a paper towel, and wipe down the entire board. (Timestamp 0:10–0:12) After the previous step, there may still be a few lingering “smudge” stains that are on the whiteboard in addition, there may be a tiny bit of residual toothpaste on the board. You may want to open a window and set up a fan in advance. This step will make your room smell very minty, or whatever scent your toothpaste is. Repeat if there are still visual stains that you can see in the area.Ĭontinue with the rest of the whiteboard until you’re left with a clean board! (As best you can, always do the circle-motion with a clean part of your washcloth, switching out washcloths as necessary.) The toothpaste will “bond” to the stains and come out onto your cloth. Using a washcloth, rub the toothpaste in circles on the whiteboard until the toothpaste has been all removed from the area.
It’s a bit hard to see, but there’s lines of toothpaste that i’ve smeared on the board there The amount of area you cover will vary, and should basically be much area as your toothpaste dollop can cover. Squeeze out two fingertips of toothpaste onto your fingers, and smear it into an 8”×8”(ish) area of the board by making “lines” of toothpaste that are separated by an inch. (Timestamp 0:01–0:09) Next, we’ll get out all of the long-term stains that are on the whiteboard.
Smudges and really old marker may be left on the board - that’s ok! we’ll remove them in the next step. Basically, you’re trying to get out as many surface stains as you can. (Timestamp 0:00–0:01) Erase the whiteboard as much as you can using just an eraser. I used about 8oz for a 6’×4’ whiteboard.Ī can of WD-40 that has a spray nozzle (not just the tube) White toothpaste (i prefer Arm and Hammer with Baking Soda ), as unscented as you can get unless you really want your room smelling like mint.
