Why You Don't Clean Acrylic With Alcohol!! (Methyl, Ethyl, Isopropanol, or Even Acetone.)

Introduction: Why You Don't Clean Acrylic With Alcohol!! (Methyl, Ethyl, Isopropanol, or Even Acetone.)

About: I am just a person who loves doing crazy and fun things... I always love to try to innovate when I can, and share any new discoveries I find... That is why I have recently started recording my shenanigans ...

Hello in this video I talk about why you shouldn't clean Acrylic with Alcohol such as Isopropanol or others as they are extremely damaging to the plastic. I also demonstrate acetone's effect on the plastic which is even worse.

In the video I offer semi real-time demos of the damage various alcohols deal to the acrylic including Isopropanol (Rubbing Alcohol), Ethanol (Drinking Alcohol), Methanol (Antifreeze/Gasoline Dryer), and Acetone (Industrial Stripping Agent.)

I also offer some information of the causes of these sensitivities, how they can be lessened, and potential theories as to why they occur. If you want to skip all that though then I'll also post a few pictures on the next page of the various solvents effects after the Acrylic edges have been heat treated and left in them for 5 minutes each.

Hopefully sharing this I can save some people accidentally destroying potentially expensive acrylic items by cleaning with alcohol. RIP my friends acrylic backed 780TIs...

Step 1: Results

In order the pictures show are Acrylic reacted with, Isopropanol 70%, Ethanol 76.5%, Methanol 100% and Acetone 100%.
Thanks for reading/watching, and have a nice day!

Side note, some other Brand Names for Acrylic that also are not safe to clean with alcohol:

"Acrylite®, Plexiglas®, Lucite®, Optix®, Polycast®, Chemcast®, Acriglas®, & Excelon®."

    I posted the note below to FB and one of my former students referred me to this video. I can attest to the fact that rinsing out an automotive tail lamp assembly with 91% isopropyl alcohol is a really bad idea. I wish my chemistry teacher had shown me how well alcohol can destroy a car tail lamp assembly!

    My post to Fb was:
    I suppose I should have paid more attention in chemistry class. I noticed moisture in the tail lamp assembly a week or so ago. I removed it and put liquid rubber where the front half seals to the back half which I’m fairly sure would solve the water ingress problem. All the gaskets and grease around the actual light sockets seemed fine.  I didn’t have it out long enough that it dried completely, so I pulled it out again today and rinsed the inside with rubbing alcohol figuring that whatever remained would evaporate more quickly than water. Instead it cracked into about 15 pieces. It doesn’t seem like it would be a pressure problem because none of the lights were installed - the back light sockets are open. I’m hoping someone who paid attention in chemistry class can tell me what happened just for closure’s sake!
