I put ethanol disinfectant into leftover empty bottles and use them.

It doesn't matter whether it's a spray type or a pump type.

I bought ethanol disinfectant from a pharmacy

I thoroughly wash and dry the empty bottle, put the product in it, pump it out, and use it to clean my vanity by applying it to the cotton pad I used for toner in the morning.

I feel a bit guilty about using a lot of disposable items, so I end up using cotton pads just to clean once and then throw them away.
