There is a thick layer of dust on the cover of this book. Alcohol should be used to wipe away dust.

You can dip a paper towel in disinfectant alcohol and then carefully wipe off the dust on the cover. After wiping, you can also dip a paper towel in water slightly and gently wipe off the smell of disinfectant alcohol. If you have a square cotton pad, you can consider using it without crumbs ~

Disinfecting alcohol can be used to erase fingerprints and dust on the screen of mobile phones and laptops, which is very effective ~

Note: Don't pour too much disinfectant alcohol to prevent books from getting wet.

I hope the above answers can help you ~
