Isopropyl Alcohol is amazing for it's cleaning properties and at higher alcohol concentrations it's safe with electronics.
Three of the best uses are:
- Removing sticky residue left by labels and tape. This will save you a lot of time and frustration.
- Cleaning touch pad button contacts, like those found in cordless phones, etc. If a button isn't responsive anymore try cleaning with this.
- Cleaning solder flux off circuit boards.
Note of warning: Alcohol is flammable, 99% much more so. Use with understanding, caution, and respect.
Now, a heads-up if you plan to go buy some Isopropyl 99%, and I recomend you do. Isopropyl can be found in any drug or grocery store, however 70% is what you will find on the shelves. Isopropyl 99% is most often kept behind the pharmacy counter. This means having to ask the pharmacist for it. For adults wanting just one bottle this will not be a problem. Young adults or those younger still may have difficulity obtaining it.
Here's why Isopropyl 99% is guarded, and it's not because they're afraid you'll drink it. Isopropyl 99% is often used in drug production. I won't go into further detail, but now you will know why the pharmacist is sizing you up before fulfilling your request.
As a related aside, I was refused Isopropyl 99% by a phamacist and this was when I was 30 or so. Actually, the guy left me standing there for 10 minutes and when he returned he said they didn't have any in stock. The reason I believe is that I was wearing scruffy clothes because of work I had been doing in my shop. I then sent my wife to the counter and strangely they had it back in stock and she encountered no long wait time. How you present yourself really does make a difference in our society. Sad but true.
Anyway, buy yourself some Isopropyl 99%. This is a shop must have.
Bonus tip: Costco (if you have access to the store) sells four packs of isopropyl 99%, not behind the counter, and it's super cheap.
