I broke up with my girlfriend and now I have to live alone and clean my apartment too. Can you please advise me the cleaning means that I can profitably use in my life?

I understand that cleaning the apartment for you is a completely new task. To make it easier for you, I recommend you to use bamboo paper towels https://amzn.to/3p5nNkd They are perfect for cleaning and are reusable. This will save you money.
