Carr & Day & Martin Ko-Cho-Line Leather Dressing 225G

Best leather treatment out there for waterproofing. Just be warned, that it will darken most, if not all leather.

I used this deep penetrating product on an old dry saddle. It brought it back to supple. Am going to use it for all my saddles and bridles.

I used Ko-Cho-Line Leather Dressing to clean 6 high quality leather dog leashes of various lengths and 2 leather dog collars that had been packed away in tightly sealed plastic storage bins for over 5 years. When I removed the leather items from the plastic bins, the doggy odor was overwhelming. I seriously debated just throwing them in the trash. Knowing how costly it was going to be to replace all of these leather items, I rashly threw them in my washing machine with copious amounts of detergent. After washing they still had a horrible doggy odor. I had read that sunlight can destroy bad odors, so I left all of them outside in the sun for several days. The smell actually disappeared but the leather items were stiff as a board. I was convinced that I had ruined them. My son, who is an equestrian, suggested that I saturate them well with Ko-Cho-Line. He is a big fan of the product and uses it on his horse tack. I donned rubber gloves and smeared the Ko-Cho-Line liberally on each piece of leather. I was very busy at the time and ended up leaving the items in a box for five or six days before I got around to wiping them off with cloth cut from an old flannel sheet. The leather is all soft and pliable. Everything was slightly tacky at first but after air drying they are all soft and supple with no tackiness or greasy feel. All of the leather pieces look wonderful. Amazing product.

Great stuff for just about any kind of leather.

Although it is sticky and messy to use, it is the best leather tack treatment available period. Smear it on. Wait. Wipe it down. Hang it up to soak in and dry. Lasts a long time. Softens, preserves and the leather feels great - like new a few days later.

I just got this product to use on a mouldy saddle. After a week and a half later the mould has not come back and leaves shiny and supple leather. The product is not smelly and looks like hot pink glue. A little of the product on a soft cloth goes a long way on the leather!

I bought an older, high quality dressage saddle whose English leather felt like it had been baked in an oven. It was dry and inflexible. I tried all of the things I usually do for a saddle that needs TLC, but nothing worked - not even my fallback method of Passier Lederbalsam. I slathered Kocholine on with my hands, careful to get it into every nook and cranny, and then let it sit overnight for at least the recommended 12 hours. Voila! The flap leather is now soft and supple, and it looks like a County saddle should. I have no idea how Kocholine works, but it DOES WORK. This is now my go-to leather care product!

perfect

the only improvement that could be would be larger containers

Used this to recondition quite a bit of old WWII leather items, and also to condition some new leather products I had acquired. Worked amazing as a conditioner, and restored everything beautifully. The colour difference was quite striking once the dried out leather had soaked up the KCL. Id say one thing to be aware of is that this is pretty heavy stuff. More like a gel than a liquid. I found it sometimes took as much as 24 hours for it to soak in. Usually just left a few spots here and there of tacky residue which you can just wipe off. This is not a fast-acting product, but the results are worth it.
