Excellent
These cleaning wipes work great for my pick up truck and they leave a new car smell. After you wipe down the surface, it leave's everything looking shiny and new. At this price it’s a very good product.

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.
