You can dry the surface with a towel or napkin, then cover the pages with a towel and press them with a weight equal to or greater than the size of the book.

How to save paper books
Read hygienically
Just don't eat while reading. If you must eat while reading, be sure to put a napkin beside you.
When the pages can't be opened, don't spit them over, use a wet sponge instead.
Protect every page of the book.
That is, when you want to mark, mark with bookmarks, and don't fold the pages.
Be sure to close it when you are not reading, or you will damage your spine.
In addition, if you must hold the book in one hand, don't fold the cover when you hold it. Otherwise, the cover will be difficult to flatten, and worse, you may damage the spine of the book.
Store paper books in a dry place.
With the increase of books, there may be no room for books on your bookshelf. Then when you store books, you must avoid damp places, and the temperature of the place where you put books must be stable. Accurately speaking, the relative humidity should be 50%, which can fluctuate 10%, and the room temperature should be 10- 18.3 degrees Celsius.
If you are still worried, you can wrap it in bubble wrap and put it in a box to prevent the pages from curling. If possible, put the box as high as a bookshelf to avoid water leakage or water ingress.
Put the books in another bag before shipment.
Even if the book looks safe in our backpack or suitcase, it will actually collide with other things, and then the fragile book will surrender first. Therefore, before you put books in your backpack or suitcase, you should put them in sealed plastic bags. If there is enough space, you can also put them in rectangular lunch boxes or other plastic containers.
Fix these books before they are completely broken.
Some books are broken at the spine, so glue should be used to stick them along the spine. The covers of some books are broken. You can make a hard-shell cover yourself.
Remember, reading often will shorten the service life of books.
Some small changes can help you keep your book for many years. If you want to collect books instead of reading them over and over again, you'd better read e-books and keep paper books. After all, every time you turn over paper books, their service life will be shortened. Although paper books cannot be as good as new forever, the above methods can make your books last for several years.
