Drivers are just realizing you can make your stinky car AC smell good as new thanks to $5 Walmart product

A MECHANIC has revealed a way that drivers can freshen up the scent of their foul-smelling AC systems.

The TikTok creator regularly shares auto content with his followers of more than 900,000 users.

Ovet Reynoso (@ovet_reynoso) posted a video on his account letting people know about an affordable product they can get to make their stinky car AC smell brand new.

"If your car A/C smells bad or like smoke here an easy fix," he captioned the clip.

In the TikTok, the user advised viewers to buy an item from Walmart or Autozone that's a little more than $5 to help the air system smell better in minutes.

Reynoso even said that the Armor All brand Armor All odor eliminator came with handy instructions showing how to use it on the back of its packaging.

The 2-ounce Armor All FRESH Fx Smoke X Rapid Auto Odor Eliminator costs $6.97 at Walmart, according to the retailer's site.

Giving a demonstration of how it works, the TikTok user said you take it out of its box and pull the folded spout out.

"While the car is off, go ahead and spray it into your vents," he said.

Then you turn your car on then turn off the recirculating air.

"Put your AC on full blast," he instructed.

Next, you're going to go outside your vehicle and see if the vents below your windshield, above your hood, are sucking air in.

Once you're sure the car is sucking air into the cabin, spray across all of the vents on both the driver and passenger side.

"Let it sit for five to 10 minutes," the mechanic advised.

"Keep in mind, this takes away smoke, stale air, mold and mildew."

The video has received nearly 400,000 likes.

Someone commented: "I changed my cabin air filter and my air still smells a little musty."

They added: "Imma have to try this."
