Triple Crown Leather Preservative & Restorer (8 oz.); 80 Year Old Fredelka Formula Hand-Poured by Accessible Preservatives; For Use on Boots, Bags, Books & More. Made in the U.S.A

Does well for my leather bound books. It does smell like animal fat though, specifically like pork fat. Regardless of smell it makes the book feel and look great.

I used this to clean / preserve antique leather book bindings. On the drier covers I used two coats and let the paste soak in for a couple of hours. After it dried I buffed them with a soft clean cloth until they were no longer tacky. This does not repair or restore leather with red rust but it takes dry, stiff leather and brings new life to the leather and wonderfully improves its suppleness so it is less likely to crack. I did not find it to be a hugely effective cleaner of stains on the leather although the cloth I used to apply the preservative did have to be rotated fairly frequently as it did pick up dirt in the process. I have used this product for a few months and the binding still look good.

Easy to use. Good quality. Will last for years. I was looking for a solution to condition my leather bound books, and was recommended this product. So happy I got it. Brings old leather books back to life with a bright, clean, non-greasy shine. Highly recommend!

Works superbly well on older leather-bound books.

Great product, works very well! We have restored several old leather bound books and they look incredible after one application. Highly recommend.

Recently I’ve been downsizing my library, selling some of my leatherbound books on the site that starts with an “e” (don’t know if we are allowed to list a competitor site), and this leather conditioner is fantastic.Not only does it clean the books and give them a great shine, it can also improve defects.It improves the look of rubbed, flat-looking areas, and in a couple of cases it completely restored them to normal.I did have to follow the instructions for best results, which can be time-consuming: I applied it, waited 24 hours, then rubbed off the excess.If I saw some improvement, I repeated the process. Once it took three times to make the defect disappear.And, of course, in many cases there was no improvement at all, but it was definitely worth a try.If you are a reseller dealing with leather books, this is a must-have!

I used this for some very old leather bound books and it brought the leather back to life. Seems like this product is first cousin to mink oil.

Created a layer of sticky crap. Ended up making my boots worse. I just bought Kiwi instead
