From the team that brought you The Last Coat, now brings you the highest performing, most advanced, and simple to use car soap and shampoo available today. 

We call it "The Last Soap" because it's the last car soap you'll ever want to use on your vehicle. Professional strength results while being incredibly simple and easy to use.

The Last Soap is infused with our popular TLC™ coating technology. This means that The Last Soap will wash, detox, seal AND revitalize the surface of any vehicle while also laying down a thin layer of our coating technology.

Now, before we get into some of the top reasons to use The Last Soap, we'd rather show you in the video below just how powerful this product is. Rarely will you see a soap actually provide hydrophobic coating protection, and rebuild a coating surface. Check out this short video and see for yourself:

Check Out How The Last Soap Helps Rebuild the Coating on This Vehicle:

Here are just a few of the reasons to use The Last Soap:

➡️ Extremely versatile. Can be used in a wash bucket or applied via foam cannon for big-time foam and fast application.

➡️ pH neutral, which means The Last Soap is gentle on any surface and coating, while also detoxing and lubricating your vehicles surface during use.

➡️ Detoxes your vehicles surface. This means The Last Soap gets in and cleans out the microscopic "pores" of your vehicles surface and of your TLC or ceramic coating layer. 

➡️ Extremely economical. Only 1-3 ounces are needed per wash, whether washing via wash bucket or foam cannon. You'll get 32 ounces of our concentrated formula per bottle. One bottle should last between 12-32 washes! 


➡️ Can be used as both a standalone maintenance soap or for detoxing your vehicle before and after coating with The Last Coat.

➡️Highly effective for preserving and rebuilding your application of The Last Coat. This will help enhance the durability of your TLC applications, saving you time and money.

➡️Helps extend the life of expensive, professionally installed ceramic coatings if you have those installed on your vehicle.

➡️Safe to use on vinyl wrapped vehicles, PPF clear bras, vinyl decals, and fiberglass surfaces such as boats and RVs.

➡️Works great on ALL exterior surfaces including chrome and glass!

Frequently Asked Questions 


We've received some great questions from our visitors and customers on how they can use The Last Soap most effectively. Here are the most common questions, answered:

Question: What exactly is in The Last Soap? What makes it so special?

Answer: Now although we don't reveal the secret sauce in any of our products, the best way to explain what's inside of The Last Soap is by saying that it's been "infused" with TLC's coating technology. The Last Soap is a hybrid soap and shampoo that not only cleans and detoxes your vehicles surface, but it also lays down a thin layer of protective, hydrophobic coating. It is, of course, our preferred car soap to use on vehicles that have been treated with TLC.

Question: Can I use The Last Soap in direct sunlight?

Answer: Yes, you can. Although it is often best to use a soap such as The Last Soap when not in direct sunlight, we know this isn't always possible. What's more important is that you fully rinse off your vehicle when you're done the washing.

Question: Can The Last Soap be used as a prep soap for TLC?

Answer: Yes, of course, that's what we do. Now, since The Last Soap is pH neutral, it isn't caustic or acidic. So, if you have previous waxes or sealants that you want to strip your surface of before applying TLC (recommended), then you may consider using a more aggressive soap such as Dawn dish soap which many of our customers do. Alternatively, you can also strip the vehicle using an alcohol wash. Or, another option is to wash your vehicle with The Last Soap, and then also use another prep of The Last Soap as a clay mitt lubricant for our Bare Slate clay mitts. This will also help you strip the surface of previous compounds. 

Question: How many washes will I get out of one 32 oz. bottle?

Answer: Whether using a foam cannon or wash buckets with The Last Soap, you should only need 1-3 ounces per wash. Go on the higher end if you like a lot of foam. So that means you will get anywhere between 10 and 30 washes per 32 ounce bottle.

Question: Can I wash my vehicle with The Last Soap without damaging my layer of TLC?

Answer: The Last Soap was specifically designed for being pH neutral and gentle on your layers of TLC or on ceramic coated vehicles. But, even more impressive is that The Last Soap will actually help rebuild your TLC layer, as well as preserve and enhance it's hydrophobic and protective effects.

Question: How long does it take to receive my package after ordering?

Answer: Currently all shipments are being fulfilled within 24-36 hours, and customers typically receive their order within 3-5 business days in the United States.

Question: Does The Last Soap work on all exterior surfaces such as chrome, glass, rims, etc?

Answer: Yes! Absolutely. We use The Last Soap internally for all exterior surfaces. It does great on glass and chrome! 

Question: Can The Last Soap be used as a clay lubricant?

Answer: Yes. We use The Last Soap with our Bare Slate clay mitts all the time. Just make sure that the surface is very slick and hydrated before rubbing your clay mitt across it.

Question: Does The Last Soap leave any streaking or residue?

Answer: No, applied correctly you should have no issue. The main thing to keep in mind is to make sure that The Last Soap is fully rinsed off after you wash, as should be done with any soap of course.

Question: Can The Last Soap be applied to a car that has a ceramic coating on it?

Answer: Yes absolutely. The Last Soap will help preserve and protect ceramic coated cars and is the ideal soap for TLC coated and ceramic coated vehicles.

Question: Do you sell gallons or only the 32 oz bottles and bundles?

Answer: We don't sell gallons of The Last Soap at this time. However, we do have our "Buy 3 Get 1 Free" bundle on this page, which is effectively 1 gallon worth of The Last Soap at reduced pricing.

Question: Does The Last Soap work on car wraps, vinyl wraps, etc.?

Answer: Yes, The Last Soap is perfect for vinyl wraps, paint protection films (clear bra). The red BMW in our demo videos for The Last Soap is vinyl wrapped!

Question: Is The Last Soap freezable or flammable?

Answer: The Last Soap is non-flammable, so you're good there. However, when storing below 32°F/0°C, it may freeze. In other words, not advised to store outside during freezing temperatures.

Question: What's the lowest temperature I can apply The Last Soap in?

Answer: We recommend the temperature being above 40 degrees when applying The Last Soap. 

Question: Do you offer a trial bottle or sample bottle of The Last Soap?

Answer: Nope, not at this time. :)


As with all of our products, The Last Soap is super-simple to use. We recommend following the directions below to get the best results:

If Washing By Hand:

• Pour 1-3 ounces of The Last Soap into a 5-gallon wash bucket.

• Proceed to use water pressure to create suds.

• Then simply begin to wash the surface with our premium 400 GSM microfiber towels or synthetic wool wash mitt. 

If Washing With a Foam Cannon:

• When using a foam cannon such as the MTM HydroParts PF-22 Foam Cannon (our preferred foam cannon), then simply combine 1-3 ounces of The Last Soap with roughly 30 ounces of water in the foam cannon. Using a heavier concentration of The Last Soap will yield more foam production.

After washing, make sure that the vehicle is rinsed completely free of The Last Soap.

For best results after washing, make sure to apply The Last Coat to further protect, shine, and seal your vehicle, resulting in world-class head-turning shine that will last up to 6 months!

Great base for laying down the shine

I felt like The Last Soap did its job well in removing the dirt. I lather and rinse frequently as the South Florida sun can bake anything in quickly. My wife's car is white, however upon washing, rinsing, and standing back for inspection, it was very apparent on spots that were missed and left grey! That's how clean the soap left it. I was impressed by how little needed to be used compared to previous soaps. I've washed 1 of 4. I can't wait to get the other 3 vehicles this clean!

The Last Coat is #1!

Forget about any other product out there. The Last Coat is #1 as far as I’m concerned. Prep is easy, and applying The Last Coat is even easier! Years ago, I used to use conventional car wax. The paste that comes in a can? Yeah, The Last Coat is the best way to go hands down!

So far I have done five vehicles stripping down& taking off all wax & coatings, with your Wash, Used Clay Bar, & then wiping vehicles down with Alcohol prior to application of The Last Coat. Two hours later a second light coat was applied. After a 12 hour cure in my heated garage, a final wipe down with a thick Micro Fiber the results were, and are stunning. I owned a detail and restoration shop and have now tossed all wax & shine products except the Last Coat in the Dumpster!DC Watson / Class Corvette,

Average Joe Review

My experience with car care products has been strongly based on the old school waxes, polishers, spray waxes and hours of working on the car. Using this product has brought me the better results than if I did a wax such as Mothers or Meguiars, but in the same amount of time as it would do for a spray wax. Insane amounts of beading and super easy. I used the last soap, regular clay bar and the last coat.

Smooth !!

I recently purchased the last coat along with the last soap and the clay mitt. I’ve used the last coat before with good results but my Jeep is 5 years old so even with the last coat it was much better but not perfect. After using the soap and mitt then the last coat, wow what a finish ! Super smooth and a great shine ! I love these products ! I’ll have to try Amp next !

2 months Since first Application

So it was back in August when I did the first application of TLC2. Found the car super easy to clean. Using The Last Soap was great! Great smelling and great foaming action. Dried vehicle and applied AMP for that silky smooth paint. Heading into winter we’ll see how it goes

Last Coat - first use on 2008 Corvette

I am very pleased with the results achieved with Last Coat. I followed the preparation instructions including use of Last Soap and the Bare Slate Clay Mitt. The gloss is amazing. Check out the pics.

Easy to use

I’m 74 and wanted something easy and still looked great. Well Last Coat is it. I’ve tried others (F11) and this last longer and the bugs come off very easy. I’m buying more!
