There are a number of reasons why leather or vinyl may become sticky. Cleaning is worth a try, but tackiness often is a sign of a deteriorating material that may not be salvageable without niche products and much experimentation.

What causes sticky leather?
Sticky leather could indicate any of the following:
- body oil saturation on full-grain, semi-aniline or aniline leather. Learn more about pre-treating or extracting oil stains here;
- excessive build-up of oil-based or silicone-based conditioners. Try cleaning with denatured alcohol or lacquer thinner;
- or a deteriorating urethane finish on bicast (or bycast) leather. Bicast leather is split hide, meaning the lower, weaker half of the hide with no epidermis (skin surface) remaining. Urethane or polyurethane finishes are used to create a new ‘skin’ surface and are notorious for losing their shine and becoming sticky and / or delaminating, peeling and flaking like bonded leather. We have not found a fool-proof blocker to correct the issue. Leather Doctor claims to have an effective process here, but it’s not simple. Our recommendation is don’t invest too much in this material. It may be easier to find a full-grain piece second-hand that can be restored and will last much longer.
What causes sticky vinyl?
Sticky vinyl, whether boat upholstery or an auto interior, indicates a plasticizer migration issue. Plasticizers are used to make vinyl (PVC) more flexible. Over time, these oily plasticizers migrate to the surface, resulting in a tacky coating that attracts all airborne debris. Sometimes the issue isn’t apparent until a new coating is applied which chemically reacts with the plasticizer.
Besides removing the plasticizers from the surface with a solvent like denatured alcohol or lacquer thinner, few products effectively prevent or correct it their continued migration outward. The consensus in the industry is that SEM® TacFree* can be applied to block and seal the plasticizers. SEM’s Technical Data Sheet recommends that this product only be used as a final topcoat and only in conjunction with their elastomeric Classic Coat*, Color Coat or Vinyl Coat*.
With that said, reviews by some folks express success with it over other coatings (though exactly what kind is unclear). Take this one from Amazon:
Rub ‘n Restore® finishes are water-based acrylics. We have not encountered sticky vinyl in a few years and thus have not had the opportunity to test its compatibility with SEM® TacFree. Proceed with caution, and test in an inconspicuous area.

What kind of “Conditioner” are talking about? I did the alchohol and mineral spirits. I agree that acetone can be dangerous, so I haven’t used that yet. I have ruined plastic with acetone.
Most leather conditioners out there are oil or silicone based and end up altering the leather’s pH (in the case of the former) or building up into a greasy slime that attracts dirt (in the case of the latter).
So in other words… I just wasted 15 minutes of my life, reading an article that doesn’t answer the question of how to correct the problem? 🙄
Me too… 😡
So basically you need to buy new
Just saw a video on this she said use oxy clean Wow works perfect
I just cleaned the waxy stickiness off our rolled and tucked vinyl dining room chairs with Oxy Clean. Worked like a charm!!

OxiClean is worth a try on sticky vinyl but is ill-advised for leather, as it is too alkaline.
TSP did the job
That’s good to know, though I would be very cautious with TSP on leather. It could stain absorbent leathers, and its alkalinity could damage the pH and fiber.
What is TSP?
Trisodium phosphate.
Worked excellent! Ty
I just bought leather furniture. I had no idea that disgusting film that I’ve seen on vinyl can also happen to leather!!! How do I prevent it from happening?
There is never sticky film on 100% genuine leather! The “leather” they produce furniture or chairs with is PU leather, which means fake. Very often! I purchased a chair for my daughter for college, and after a few years, the chair became completely worn out, heh! It is so gross! Now, I have shoes made in China that are supposed to be made of real leather, and it appeared to be fake leather and very sticky. Also, I purchased in a department store 100% genuine leather belt. After going to work for three months, the belt split on the buckle and the inside appeared to be gray paper. The belt was soaked in a leather-smelling liquid, so I was fooled.
Even the term “genuine leather” has been used to mislead consumers, often referring to low quality split-grain. It wasn’t until 2017 that “leather” came under US regulation. Even so, “genuine” is not mentioned. More info about the types of leather can be found here.
If you bought it new recently, and it’s delaminating, it’s likely a polyurethane-coated bonded or faux leather (click here). Stickiness would indicate one the materials or issues noted above.
White vinegar will remove the tacky surface on Vinyl. Let it soak in for 5 minutes and scrub lightly with a sponge. Rinse and repeat. Rinse once more and let air dry. It works on old vehicle steering wheels and dash boards also.
Bonus note: White viniger is what should be used to clean electronic surfaces damaged by alkaline batteries. The vinegar will neutralize the alkaline caustic. Use a toothbrush to scrub the surfaces then rinse with water. Dry thoroughly and let set for a day in a low humidity room before installing new batteries. FYI – during manufacturing, alkaline batteries are submerged in an low acidic wash, rinsed again and then blow dried before final packageing to remove surface caustics.
Great to know about batteries. White vinegar is always a safe starting point, but a stronger solvent is often needed. Household white vinegar is 90-95% water with a pH around 2.5 (acidic), whereas rubbing alcohol is only 10-30% water with a pH of 6-8, making it more netural.
I’ve figured out the only solution to this problem that REALLY works! Sprinkle any talc powder (I use a foot powder!) and rub it is vigorously. It looks messy at this point…do it over a sink or outside. Now, use a soft cloth to rub the excess powder off. Keep doing this, the more you do, the more it looks like the original finish. The result is the tackiness is 100% gone.
Amazing solution, thank you! Beware though, many talcum powders are contaminated with asbestos and are considered carinogenic. Even asbestos-free talc can irritate the nose, throat and lungs, and chronic exposure can scar the lungs and lead to shortness of breath and cough, possible disability, and even death.
I have my wedding album which is vinyl and has become very tacky for so some reason. I can’t even hold it because it’s so sticky. Does anyone know the best way for me to clean it without ruining the integrity of the photo album?
