McKee's 37 Interior Surface Protectant 128 oz.

Stop the aging process of your vehicle’s interior!

McKee's 37 Interior Surface Protectant is a multi-surface shield for your vehicle’s interior. It maintains the supple, fresh texture of vinyl, leather, plastic, and rubber while blocking out harmful UV rays. Treated surfaces resist fading, drying, and cracking so your interior maintains a fresh new look. McKee's 37 Interior Surface Protectant keeps interior surfaces looking like new for the life of your vehicle.

McKee's 37 Interior Surface Protectant penetrates the surface to create an invisible shield that repels water and dirt so interior surfaces require less cleaning. In the long run, your vehicle’s seats, door panels, and dashboard will resist aging.

In addition to UV blockers, McKee's 37 Interior Surface Protectant contains a mild cleaner to remove surface dust and dirt. In most cases, this may be the only product you need to clean and preserve your interior. However, if your interior surfaces are badly soiled or neglected, use McKee's 37 Total Interior Cleaner to remove severe soil. Follow with McKee's 37 Interior Surface Protectant to maintain the clean appearance.

Interior Surface Protectant is water based and non greasy
Tip: Bury the nozzle in a microfiber applicator to avoid overspray
Apply to all interior surfaces except suede
Then, apply a thin coat to the desired surface

The finish created by McKee's 37 Interior Surface Protectant is not greasy or shiny. It simply restores the original appearance and texture of the material. Faded dashboards will be restored to their original color and dry hardened leather will be dark and soft again. Because the protectant penetrates below the surface, it will not attract dust and dirt or turn yellow.

McKee's 37 Interior Surface Protectant is silicone-free and VOC compliant.

Treat all finished leather, colored plastic, vinyl, and rubber as often as you like without fear of clouding or discoloration. For optimum protection, reapply McKee's 37 Interior Surface Protectant every two to three weeks.

Since McKee's 37 Interior Surface Protectant works on so many surfaces, it is an economical choice for professional detailers and enthusiasts. Just spray and wipe to thoroughly protect your vehicle’s interior from the effects of age and sun exposure.

Do not use on suede.


  1. If your interior is badly soiled, use McKee's 37 Total Interior Cleaner to remove tough spots from the vinyl, plastic, and rubber.
  2. Spray a microfiber applicator pad with McKee's 37 Interior Surface Protectant and wipe the dashboard, trim, and door panels.

While great for car interior vinyl and leather, wife and I found it great on old formica-topped tables - makes them smooth and clean with no sticky or greasy feel..
ProsMuch better than A**A** products Protects better Lasts longer Smells better
ConsCosts a little more than the cheap stuff (to be expected) but not as much as other high-end protectants

Great stuff for my interior
I would give 5 stars except for one technicality, which is the difficulty in applying. I wish I could give it 9 out of 10 stars. I ordered the $5 sprayer along with this stuff. This stuff is thick and creamy. I screwed the sprayer on and quickly learned that you have to remove the small cap at the bottom of the sprayer tube. My car is a 2014 Mazda 3 i Grand Touring with only 10,000 miles, so it was not in rough shape, but I want to maintain it. Directions said to clean surface dirt first. Other than vacuuming the car, I cleaned nothing first. I sprayed generously and wiped this stuff into the leatherette (high quality vinyl) seats, dash, door panels, everything but the windows. I used the nice soft cloths that I also ordered from AutoGeek. The interior came out sparkling clean and with a beautiful sheen and a nice leathery smell. The sprayer got clogged at one point, I think because the stuff is so thick. I unscrewed the sprayer from the top, and ran it under warm water. I stuck the bottom of the sprayer tube into a glass of warm water and kept squeezing the trigger of the sprayer until I got water to spray out. I then screwed the sprayer back onto the jug of this wonderful stuff and got it spraying the stuff and finished the job. I used this stuff on interior leather furniture also. Great stuff.
ProsLeaves a beautiful clean sheen on all leather and vinyl surfaces. A nice smell. It is awesome stuff.
ConsGetting sprayer applicator to work. You could pour the stuff, I suppose, but when the sprayer was co-operative, it applies much more evenly without over applying.
