Review on ✨ Absorene Bundle: Book Cleaner and Dirt Eraser (2 Items) - Remove Dust and Dirt from Books and Documents with Ease by David Chen

I have several used books, the edge/side of the book is dirty. After using the edge cleaner it's still as dirty as before leaving lots of pink residue that hardens between pages very quickly. It took me almost an hour to get rid of all the pink residue page by page. I believe this product is for surface cleaning only (which I have tried on several sites and the results are way below my expectations) and you need to be very careful. you have been warned
