Nice products with great results
I purchased the Meguiars supreme shine protectant wipes to keep in my car for touch ups when things need a little freshening up. It is easy to use, nothing to spray and keeps my interior looking like new. Nice and black. It also protects my dashboard from the harmful sun rays. It has a pleasant smell as well.

Great product before they dry up
Great smelling product, that performs and protects and a high level. It left my car looking and smelling good with its unique scent and formula. I usually keep these inside my glove box since they’re so compact I can easily get the container and wipe when needed. The wipes retain its moisture fairly decently. I find that if I don’t use all of the wipes within a 2-3 month time frame, they will dry up and be no good. As long as you use them up before that it’s a nice buy for your vehicle.

Smells good and conditions dash well
Dust is sticking to my dash more but that’s to be expected I think. My kid also starting trying to clean the back windows with them and they streaked them up, so not for windows. Seals tight, seems like they will last a while.

Love that scent
I have been using Maguiar’s products for decades. I purchased these wipes shortly after I used one of their spray on detailing products in my garage. In that setting, the detail spray scent was addictive…almost like a tropical suntan lotion. Normally, I am not much on scents that can be overwhelming…like plug in house products or those things sit in your vehicle vents… they tend to be too strong and/or too pervasive. But in a garage, and diluted with the surrounding air…that detailing product scent was luscious, just enough, not too much. That scent prompted me to search online for “Maguiar’s wax scent” and I found some user forums discussing this topic. Lots of people think similar things and compare various other products. I learned that Maguiar’s recognized the marketing importance of scent in their products a while back, but I had never really noticed it, although it has always been my go to product line for wax and detailing products. This encouraged me to order some of these wipes for cleaning interior surfaces. I was not disappointed! The new car scent is just enough “new plastic” mixed with some sweetness of those other signature tropical notes to add a nice touch to the cleaning activity, while being just lightly persistent enough to make you notice that scent when you get into a freshly cleaned vehicle. I would not want that same scent to be too strong or persistent, and it is not. Additionally, as a cleaning product, it works very well. The dashboard plastics end up more matte than glossy with application, something else I appreciate. I am not a fan of super shiny or glossy. Thanks for a great product Maguiars!
