[Lifehack] Rubbing Alcohol + Spray Nozzle = White Board Cleaner, Disinfectant Spray, Etc.




Introduction: [Lifehack] Rubbing Alcohol + Spray Nozzle = White Board Cleaner, Disinfectant Spray, Etc.

About: I'm an inventor, poet, permaculture / sustainability nerd, and activist. I work in the renewable energy industry with biomass gasification. I love to show people neat tricks to optimize things, and I want th...

I noticed that a 22oz bottle of white board cleaner costs about $7-$9 at most office supply vendors. What a rip-off. As far as I can tell, it is virtually identical to rubbing alcohol. I can get 32oz (1 quart) of rubbing alcohol for $2.30 at my local market, and I can't tell the difference. In fact, it seemed to me to work even better than the dry-erase cleaner spray. If I can't tell the difference, I shouldn't have to pay the difference, and neither should you.

Get yourself a spray nozzle; you can either recover one from an empty spray bottle of some sort of household cleaner and clean it off by spraying some hot water through it. Alternative, you can buy them cheap. I got a pair at Daiso for $1.50. Then get yourself some rubbing alcohol (isopropyl alcohol), and replace the cap with the spray nozzle. It should be an exact fit. Then get yourself a microfiber cloth, and you're set. While you're at it, get a whole stack of microfiber cloths from Target or Costco. 

What is this good for?

* cleaning white boards until they gleam like new. 
* glass cleaner
* disinfectant spray
* cleaning finger prints and things stained by greasy hands. Rubbing alcohol can cut grease just enough. Microfiber helps.
* cleaning glasses
* cleaning and disinfecting smart phone screens
* cleaning and disinfecting laptop keyboards and screens

Anything you need to clean that benefits from a little moisture and quick drying can be cleaned this way. Besides being cheap, rubbing alcohol is also non-toxic and kills germs. Why isn't everyone using rubbing alcohol instead of expensive cleaners? I 

Rubbing alcohol is usually sold in 70% strength and 90% or 99% concentrations. I find that 70% works just fine, whereas the higher concentrations leave a strong alcohol odor. If you are cleaning your laptop keyboard, and are concerned about water exposure, go ahead and use the 99% concentration. Or, just spray the cloth lightly rather than spraying your keyboard.

    It won't necessarily damage the board right away but overtime you'll see that your whiteboard will start "repelling" any marks made on it and ghosting will become a serious problem.

    I don't think it does. The main ingredient or dry-erase board cleaner is isopropyl alcoho as far as I understand.

    You might want to consider that in most cases, using alcohol can void any warranty bought with the whiteboard. Even so, if you don't care about the warranty, alcohol tends to strip the surface of the white board so any writing there on after will just stain it even worse. A great article that considers this can be found at the link below:
