Del Taco already is known for serving Crinkle Cut Fries along with tacos.

Now the fast-food chain with 580 restaurants in 14 states has cooked up two new fry-related creations – a lightly French fry-scented soap and Fresh Faves Box meals that include fries.

Unlike the Fresh Faves meals available in four varieties at locations nationwide, the limited-edition soap called “Eau De French Fry” is not on the menu.

"Stay fresh with soap that will make you smell as exquisite as the world-famous fries we include in every Fresh Faves Box Meal," the soap box says, noting, "Brought to you by the hardest working hands in fast food."

Del Taco is giving away free bars of soap on its Instagram page Tuesday to guests who post a photo of their Fresh Faves Box and tag the brand. On Wednesday, the soap will be available to purchase for $3.95 plus shipping at www.deltacowebstore.com, while supplies last. The store also sells clothes, accessories and packets of hot sauce.

Barry Westrum, Del Taco’s chief marketing officer, said the fries are a fan favorite and have been on the chain’s menu consistently for more than 50 years.

Why the soap?

“We’ve seen fantastic engagement when offering whimsical and timely products that have a fun tie-in with product launches, such as the burrito wrapping paper we offered last holiday season to celebrate our Epic Triple Meat Burrito,” Westrum said in a statement to USA TODAY. “Obviously, we’re looking forward to ‘freshening up’ the fast food value box category in more ways than one!”

Past fast-food chain special product launches have sold out fast.

In December, KFC firelogs that smelled like fried chicken sold out in hours.
