Whistle Express Car Wash

Amazing car wash! My car is so clean it’s like I’m driving straight off the dealerships parking lot! Highly recommend! Big thanks to Mason for checking in with us and making sure we were satisfied customers. We will definitely be back.

Came during the grand opening (didn’t know it was) and they gave me the top of the line was for free. This truck is a Florida truck so never seen the salt and snow but knocked all that off. Good customer service and amenities. The dryers could use some work and wheel cleaners but nothing that a rag can’t wipe off.

Whistle Express Car Wash is superior to any other car wash in the area—especially the Northglenn location! We came last Saturday to get my car washed, and they were offering free car washes. We came back again today with my wife’s car and again received a free car wash. Mason, the manager, came up to us to make sure the wash didn’t damage our car and to ensure we had a good experience. He also mentioned they’re running the free car washes until February 12th. I highly recommend this car wash, especially after the snow when your car is screaming for a cleaning. PS: This car wash also offers undercarriage washes with their packages, which is a huge selling point for me.

This is the best car wash! We love it even more since the rebrand. It gets all the dirt off our car and the new car mat cleaners are fantastic. We talked to Abe and he was super helpful and friendly! We will definitely be back.

As I was drying my car (Toyota Camry in light gold color) I noticed some small black goopy specks in a few places through out my car it wasn’t a big deal I assumed that there was a little residue on the cleaners or something. I was able to buff these little specs out. I then noticed a huge spray of this residue all over the passenger side of my car. It was on the bottom along the entire length of the car. The residue was so thickly splattered on that it was not coming off easily. This is when I called over the first employee working by the kiosks. He told me he was going to check out what happened and report back to me. He never came back. I called over a second employee and explained the
