In the States, I used to buy a huge bottle of eyeglass cleaning solution from Costco, and that would last me many years. As there is no Costco in Singapore, I decided to just make my own solution. It turns out that making a solution is way cheaper than buying one, even if you are able to buy in bulk (like Costco).
It’s also really simple! And chances are, I bet you already have all the ingredients available in your home.
In a spray bottle, I mix:
- 3/4 part rubbing (isopropyl) alcohol
- 1/4 part water
- a few drops of dish soap (depending on the size of the container)
As always, the cheapest place that I could find rubbing alcohol is at Mustafa Centre ($5.80 for 500mL).
