Whether you got oven cleaner on fabric, tile, wood, or terrazzo, there’s a way to get it off. Howstuffworks.com lays it all out, starting with:

To remove oven cleaner stains from acetate, acrylic fabric, carpet (synthetic or wool),
modacrylic, nylon, olefin, polyester, rayon, silk, spandex, triacetate, wool...

Sponge the stain with cool water. If stain persists, neutralize the spot with a few drops of a mild acid, such as lemon juice, white vinegar, or 10 percent acetic acid solution. Thoroughly sponge the area with cool water. Silk and wool must be treated promptly, as oven cleaner will destroy these fabrics.
