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.

I am dissappointed paying $50 expected it to at least remove toothpaste bathroom mirror . Bought product fir glass shower doors as my water is hard and always leaves spots and film paid the money so the protectant in your polish would prevent this as I squeeze my doors after each shower and yes I have cleaned the doors before used your product..but I will use as already paid for. If I buy again do not know will look for a better product that protects spots from forming. Thanks for asking it shows you care I always want to do buisness with companies who ask what I think

Hi Renee, thank you for taking the time to share your experience — I genuinely appreciate the feedback.
I did try reaching out by phone and left a voicemail, and I also followed up by text because I wanted to personally make sure you were taken care of. I’m sorry we weren’t able to connect directly.
I want to be very clear for you and for anyone reading this: Koenig Polish is fully guaranteed. If the product doesn’t meet your expectations, I’m happy to offer a refund or replacement, no questions asked.
With very hard water conditions, minerals can still form deposits on shower glass over time, even when doors are squeegeed daily. Some customers see improved cleaning ease rather than complete spot prevention. That said, if it didn’t deliver the results you were hoping for, that’s on me to make right.
I truly appreciate you sharing your thoughts — feedback like this helps us improve, and I always want customers to feel heard and supported. Please feel free to reach out to me directly so I can take care of this for you.

Better than Expected
I have a 7 year old boat with a black hull. Over the past few years I hired someone to compound and wax the boat at the beginning of each season. Each year the results became more and more unsatisfactory. Last Spring I decided to take a chance on your product. I was amazed when I saw the results. The oxidation was hardly noticeable and the shine was fantastic. AND it was easy to use. People at the marina were very impressed. Doing the boat the first time did take the most effort but anytime after that it was easy peasy. I just received 2 more cans for this upcoming season.

This is the same polish that has been used on my 1963 corvette by the original owner. The results are great! I will use this on all of my vehicles from now on!

I love this product
I love this product. I have tried others like this because they were a bit cheaper. I couldn't wait to reorder the Koenig. The company is excellent. I had a problem and they quickly responded and made it good . So refreshing!

Hi Kevin, Thank you so much for the great review — we really appreciate you taking the time to share your experience.
We’re glad to hear the shipping updates were helpful and that Koenig Polish exceeded your expectations. Hearing that it removed heavy dirt and grime from your work truck and then delivered a show-car shine on your personal vehicle is exactly what we designed it to do.
We also appreciate you mentioning the lack of harsh chemical smell — that’s an important part of what makes Koenig Polish different and more enjoyable to use.
Thanks again for your support, and if you ever have any questions or need anything at all, just let us know.

Hi Wayne,
Thank you for your order and for taking the time to leave a review. I’m very sorry that your email didn’t receive a response — that’s on us, and we’re improving our support process so it doesn’t happen again.
To answer your question clearly:
👉 Koenig Polish has an extremely long shelf life — typically 20+ years when stored at room temperature.
It does not separate, expire, or degrade the way many polishes do.
If you have any other questions or need help with anything at all, I’m here and happy to assist.
Thank you again for giving us a try.

Good experience so far.
I won’t be able to use your product until spring so until then I can’t say how good or bad the product is. So I will reserve that judgment for later. The only hitch I had during the order is an email was sent to me saying it was on its way, but when I checked the status days later it said the order was canceled. I had no notification on that so I called your customer service which informed me it was canceled because they chose a different warehouse to send it from and the order was delayed a few days because of that. They did assure me the order was now on its way. I just felt I should have been notified as soon as the original order was canceled. I shouldn’t have had to call you to find that out. It’s just a small thing and kind of a nitpicking thing, but could make your company a better one in the future. Otherwise I had a good experience with you and looking forward to applying your product in the spring. Thank you.

Hi Putzer — thank you for taking the time to leave such a detailed review and for giving Koenig Polish a try!
We completely understand your frustration with the confusing shipping notice and appreciate you bringing it to our attention. What happened was an internal warehouse transfer that caused an automatic cancel/re-ship without the proper email update — and you’re absolutely right, we should have notified you immediately.
We’ve already adjusted our order-notification process so future customers receive real-time tracking when a warehouse switch occurs. Your feedback directly helped us make that improvement — thank you!
We’re glad the order reached you safely, and we can’t wait for you to see what the polish can do once spring rolls around. If you have any questions or need tips for best results, just reach out anytime — we’re happy to help!

Easy application
Have used this product for maybe 25 years. Mainly on my vehicles. This time my wife tried it on our kitchen granite. She was pleasantly impressed with the results. Which now we only need one product to keep up our (black ) granite. Now I have to hide a can for my vehicles.
