Meredith Marks’ bathtub isn’t the only thing she’s keeping squeaky clean.

The “RHOSLC” star told Page Six she picked up an unexpected laundry hack from co-star Mary Cosby: using Dawn Powerwash Dish Spray ($5) on clothing.

“A holy grail product I use is spray Dawn dish detergent” the Bravoleb said during a “Virtual Realitea” podcast taping , explaining Cosby advised her to spritz some on stained garments, let it sit for 10 minutes and then “throw it in the laundry.”

The “RHOSLC” women aren’t alone in sharing the stain removal secret; a commenter on Page Six’s Instagram gushed, “I do this too and a few other women I know does [sic] it too, it really works!”
