Whet your appetite with our Auto Refreshener No. 4 Recipe Guide!


Auto Refreshener is fueled by a potent emulsion of oils nutrients specially designed for auto leather. Whether it be motorcycle, vinyl or traditional car leather, you’ll be hard pressed to find any leather conditioner as competitive as Recipe No.4. With a rich, creamy texture and balanced pH, this conditioner stands above its peers for its FDA approved, cosmetic grade ingredients: entirely natural, environmentally friendly, and hand-picked for perfection. In fact, we’ve even watched some people drink Leather Milk straight out of the bottle! We wouldn’t personally advise doing this, of course! Auto Refreshener is also enhanced with an exotic coconut fragrance: a subtle sensation designed to maximize your conditioning experience, but lasting only as long as the conditioner takes to absorb. We’re as much a fan of your leather’s natural scent as you are!


In addition to giving your leather protection from spills and stains, Auto Refreshener also possesses key UV protectants that ward off harmful ultraviolet rays. These protectants prevent leather from fading or drying out prematurely due to sunlight. They can also be helpful for other types of leather exposed to regular sunlight as well, such as couches and saddlebags. If you plan to be wearing your sunglasses a lot where you’re going, you should bring Auto Refreshener along on shotgun.


Like all of Chamberlain’s leather conditioners, Recipe No.4 should enrich your leather’s color and give it the soft, supple texture that it deserves. As this recipe absorbs and conditions, it will strengthen the fibers of your leather, making it grow stronger, and live longer. A light cleaning element permits Auto Refreshener to give your leather a gentle surface cleansing, and its protective properties allow it to moderately repel routine contaminants, such as spills and dirt. If you have already used Auto Refreshener, you will not need to apply any other leather conditioners to your leather, at least until it is ready to be conditioned again. All Leather Milk products are made in USA.

    Formula No 4

    I have been using this for years, it has a very nice smell to it and also conditions the leather. Living in Texas it also has UV protection and I need that.

    The Beauty of Leather Milk

    Posted by Jeff Herman on Jun 21st 2021

    I’m a silver conservator and I know a little something about surface finishes. I ordered Leathermilk #4 primarily because it’s non-toxic and I saw virtually all positive reviews. But it was the non-toxic aspect I was primarily looking for. It did a beautiful job on my 2012 Subaru Outback wagon. It didn’t make the leather look glossy new, and that’s not what I was looking for. I wanted something that would clean, nourish, and smooth-out the micro-stretches and cracks that form over time, and bring the surface back to life. And it did exactly that. Leathermilk also smells nice, not at all chemically. It dried quickly as well. I purchased the 6oz. bottle and used only about one tenth of the contents. So at $23.90 including shipping, it’s pretty cheap at a little over $2 per application. And it comes with a hearty applicator that's easy to clean. Again: It’s NON-TOXIC!

    I'm pretty lazy and hadn't added any protection to my car interior surfaces in a very long time. Now I see why. Once I started with this bottle I discovered how much danged vinyl I've got in my two-passenger truck! Still, had a nice, faint almondy smell, cleaned things up and left an shiny, newish-looking surface behind. I don't know how long before I'll need to re-apply, but for my small truck it looks like there'll be enough for many years worth of applications.

    A bit expensive buy does the job. I own a 2008 BMW and this product rejuvenated 5 year old leather. I'll continue to buy and use this product.

    My boyfriend has a 2010 Honda Civic that is constantly exposed to the intense sun here in Hawaii. He rarely cleans it, and the leather on the steering wheel was turning gray because of the accumulated salt, oil and dirt build up from his sweaty palms. He asked me what to use and I found this product on Amazon and thought I'd give it a shot. I used a microfiber cloth and, although I did need to rub it a bit, it seems to have cleaned the leather and conditioned it, all in one step. I couldn't believe how easily it removed the grime. The leather was already a little cracked, but you can't really tell by looking at it because it is so well conditioned. I applied it also to the vinyl in the car, and it seemed to clean it equally well. I like that the surfaces look clean, but are not overly shiny. This is important because I used it on the dashboard, and I wouldn't want it to cause any excessive glare. The true test of this product will be to see how it performs over time, but I am loving it so far. The company really seems to strive to improve as they sent me an email to see how I liked their product. Great product from a great company.

    Does a great job on car leather but was even more impressive on our leather dining stools. Keep in mind it is a liquid, not a cream. So a little goes a long way.

    just as described. goes on easy and does an excellent job. no bad order, cleans very well and looks excellent when dry. I have a 2012 Limited Ram 1500 with less than 1800 miles on it with all black leather. After using Chamberlains on my interior, it looks better then the day I picked the truck up from the dealer., when my bottle runs out will purchase another one. Only issue is the bottle is easy to tip over, but in an email from chamberlains they are fixing this with a slightly different look, well done chamberlains.

    Our specialty is restoring classic automobiles to showroom condition, both inside and out. When I have a special leather interior to clean and condition, I want something that rejuvenates the leather and really makes it stand out; and, I want a product that is safe to use on vintage leather surfaces. I really like Chamberlain’s Leather Milk for all of these reasons, and I recommend it enthusiastically!- Steve FoxFFF AUTOMOTIVE RESTORATION FORT WORTH, TEXAS

    This leather conditioner and cleaner really works. It has a nice smell and a creamy formula. I really love the sponge that comes with it. A nice size and worked really well. Cleaning the leather seats showed all the dirt that was on my car seats. I was surprised how much dirt ended up on the sponge. The sponge cleaned up nicely with warm water and soap. When I run out of Chamberlains, I will not hesitate to buy it again.

    I am not known by my family for spending a lot of time and attention on my cars. But it was looking pretty bad even by my standards! I had been so pleased by the other Chamberlain products that I thought I would give their #4 a try. It was very easy to apply, worked instantly and smelled great when I had finished. It immediately gave my car that detailed look! My wife even noticed! I was especially pleased that it removed the light scratches that were on the passenger side dashboard that seems to double as a footrest. Another great product from Chamberlain, thanks!
