    C.G. Delivers Once Again -- Would Expect Nothing Less !!!
    LOVE CHEM GUYS. these little wipes are awesome for quick cleaning. and to leave in the trunk of the car for UBER Driving. i love the VRP Hydro Spray - but you still need a rag to wipe it around. this solves that problem. just need 2 to clean the whole car !! and i have weather.tech floor mats front and back. these VPR Wipes make them look brand new in 5sec flat. and makes the black plastic car trim look sexy AF. NGL. but i dont like it on the leather seats. its a little too slippery for me. i like the OG Leather Conditioner for that. the cleaning wipes are really good too. can use them for any/every thing. one square will die out kinda quick, but it you use 2, it lasts a long azz time. (Clean Wipes AND VRP Wipes)

    Alright
    The interior cleaner are a little too dry for my liking- it feels like I need to use multiple wipes for the same area. I like the VPR for the plastics around the car (looks a little greasy), but I don’t think $20 is worth only 30 wipes each. I would rather buy the spray. Maybe I’m not using the wipes correctly but “shines like new” didn’t happened on the doors.

    Excellent combo pack.
    The cleaner & protectant and VRP protectant are my new go to cleaner and protectant wipes, I’ve been using another brand for 30+ years but it’s time to try other brands, I bought these to give it a try and it didn’t disappoint, it works very well, I work in very dusty environments trying to clean and protect the interior is an ongoing battle, so far this combo cleaner and protectant is doing its thing as expected, the cleaner wipes are not heavily soaked but with just the right amount without leaving any streaks and the same goes for the protectant wipes.
