I've become a loyal customer ever since my first 2 cans I purchased at the RV show. I now use it on my vehicles, house widows, stainless steel and anything else that needs to be protected.
Company details
Written by the company
If you take pride in the appearance of your vehicle, you know that detailing is not just a chore; it is a series of chores that require a variety of waxes, polishes, and cleaners, in order to properly finish the job. If you are like us, you’ve dreamed of a single product that could not only take the place of all the all the rest but outperform them as well. We searched far and wide to find the perfect all-in-one solution, but no other all-purpose products on the market worked as well hoped, so we set out to invent our own. Our goal was to make one product that would allow the “average person” to clean like a professional. We accomplished that goal in 2002 with our revolutionary new product called EZdetailer. Little did we know at the time, but the “average person” we designed EZdetailer for was far from average! Fans of EZdetailer were not only telling us how much they loved using the product on cars, boats, and airplanes, but they also used it inside the house and discovered that this all-purpose cleaner had dozes of household uses as well! One bottle not only handles tough road grime and bathroom filth but is also gentle enough to clean window glass and even granite countertops. With so much possibility packed into one bottle, we felt the name EZdetailer was too specific and too general for such a fantastic product. In 2014, we rebranded as Koenig Polish - a fresh new unmistakable visual identity for our same beloved product. Aside from the name, nothing else has changed and our original all-in-one formula remains the same. Koenig Polish is your one bottle solution for cleaning, shining, restoration and protection.

Hi Lee,
Thank you for your feedback and for giving Koenig Polish a try on both your RV and headlights. We appreciate you taking the time to leave a review.
For heavier oxidation on fiberglass RV surfaces, we typically recommend using Koenig Polish with a quality buffer/polisher rather than by hand. Severely oxidized surfaces often require machine application to fully restore the shine and remove deeper oxidation.
For headlights, Koenig Polish can improve oxidation and clarity, but heavily weathered headlights may require additional restoration steps similar to professional restoration kits. On our website we have detailed instructions and videos showing how to use sandpaper followed by a buffer/polisher for more advanced headlight restoration results.
If you would like, feel free to contact us directly and we would be happy to help recommend the best process based on the condition of your RV or headlights.
Thank you again for your support.

I don’t think it’s the same product or recipe as the ez-detailer. It definitely doesn’t smell the same, and doesn’t work the same. As advertised it says
ez = Koenig.
But it is not the same

Hi Tost,
Thank you for your feedback and for being familiar with EZdetailer.
I understand why the change in branding may have caused some confusion, but I would like to clarify that EZdetailer and Koenig Polish are in fact the same original product. In 2014 we rebranded from EZdetailer to Koenig Polish because many customers were using the product far beyond automotive detailing — including shower glass, stainless steel, boats, RVs, kitchens, and household surfaces — and we felt the new name better represented the versatility of the product.
The original all-in-one formula remained the same during the rebrand.
That said, because the product has been manufactured over many years through different production facilities and ingredient sourcing environments, there can occasionally be slight differences in smell, appearance, or spray characteristics from batch to batch, even while maintaining the intended formula and performance profile.
I started this company over 24 years ago and genuinely care about customer satisfaction, so I appreciate you taking the time to share your experience. If there is a specific application where you feel the product is not performing correctly, I would be happy to discuss it further and help troubleshoot the issue directly.
Please feel free to contact me anytime.
Thank you,
Dan Clark

I try using your product on my car and it didn't work like. I thought it would. I'm still gonna have to get another thing from the parts place to see if it can take this grime off my headlights.

Hi Don,
I just tried giving you a call regarding your recent experience with Koenig Polish and wanted to personally follow up.
I’m sorry to hear that the product didn’t perform the way you expected on your headlights. Headlight restoration can vary quite a bit depending on the level of oxidation and buildup, and in some cases a specific process may be required to achieve the best results.
We do have instructional videos and recommended application methods available on our website that may help:

I started Koenig Polish over 24 years ago and we’re still a family-run company, so customer satisfaction is very important to us. I’d genuinely appreciate the opportunity to better understand the issue and see if we can help improve the results for you.
If after trying the recommended process you still are not satisfied, the product is backed by our satisfaction guarantee.
Please feel free to reply to my email that I have sent you or give me a call when you have a chance.
Thank you,

Hi Federico,
Thank you for your review, and I’m really glad we were able to connect by phone to go over everything together.
I want to clarify a couple of things to help you get the best results:
Koenig Polish isn’t designed for use on leather, so it won’t perform properly on that surface. For your shower doors, the water spots you’re seeing are typically mineral buildup, which can require a little extra prep the first time. As we discussed, using 0000 steel wool along with Koenig Polish will remove that buildup, and once it’s clean, the surface will maintain a hydrophobic, water-repelling effect.
For your boat, using the product with a buffer on the first application will give you the best results and really bring out the shine and protection.
We also have step-by-step training videos on our website that walk through each of these use cases so you can see exactly how to apply it.
I’ll follow up with you next week as promised to make sure everything is working the way it should. We stand behind the product and want to make sure you get the results you’re expecting.
Thanks again for your time and for giving us the opportunity to help.
— Dan

AWESOME!!
This polish works fantastic on my hard and soft clear flybridge enclosure. Everything else I tried streaked, scratched and was nothing but difficult. This product is a must on clear enclosures.

Amazing Product
Originally found this years ago at Costco at one of their special vendor events they used to have. Bought a few cases of it then and have been using and giving it away to other RVer's since. This polish is incredible to use on the RV. It works as well as it's promoted to work. Just bought another case of it to be able to keep using it and keeping my RV shining.

GOENIG and Dan Clark incomparable!!wrote a review in Jan of only 2 stars…
I wrote a review in Jan of only 2 stars after trying tge products I waited a year to buyout did NIT wanna spend $50 on a cleaner..to my surprise I got a phone call and an email from Dan Clark of Koenig..WOW. Who does this??To be clear I always research and read reviews I do all my shopping online and alot of it is ripoff even the companies that offer guarantees. There is always a catch on returns..but Dan was kin enough to ask how he could help me with the product..what was I using it on..how was I cleaning with it ..I have hard water. Oman the kind even after you scrub. There ut still is. I spent $20k for a beautiful marble walk in shower with glass doirs which I spray and squiggly after each use yet there are those spots and brown build up. So Dan again was there and responding to my emails offering assistance..I mean some companies will reach out to ask you unhappy with product. But NEVER have I seen anyone who really CARED what I thought and really wanted to help and believed in their product so strongly..I am beyond impressed..I mean when do you see this happen?? Even the handful of products I buy and use religiously..and spend thousands of dollars NO ONE EVER called me..I am blown away by this man and I am no young impressionable lady..If I could I would hug this man as I am shocked by his character and his heart and dedication to his product..He cares about his customers and product. This is rare and deserves attention..so I am changing my review to 5 stars...and my heartfelt thanks to Dan Clark you are truly unique in a day when we literally have the world of choices at our fingertips...Anyone considering this company and product should 100% buy Koenig. I wish I could share a picture. Sorry do not see that option here..(hey Dan maybe be cool to put spot here for pics??) But the polish works great on mirrors. Sadly it not stop the dust ha ha but please people give this product a chance ..ypu have nothing to loose and the world without a doubt needs more people like Dan Clark
