About a year ago, my mother-in-law spilled a bottle of vegetable oil. Using a handful of kitchen towels, I jumped in to help mop it up — which just made a bigger mess. Then, after hours of cleanup, I tossed the towels into the washing machine, and trying to be efficient, washed them with some other dirty clothes. A second BIG mistake. My kids and poor husband smelled like a bottle of canola oil for days.
Never wanting this to happen again, I’ve made it a mission to find the best way to clean a cooking oil spill. The following method is fast, effective, and best of all, won’t have everyone smelling like the back of a diner. A job well done, if I say so myself.

The best way to clean a cooking oil spill
1. Soak up the excess oil with paper towels or old dish towels (that you make sure to wash separately) using a dabbing motion. Do not wipe or you risk spreading the oil further. If a glass bottle has broken, too, carefully pick up and wrap the glass pieces in newspaper or collect them in a brown paper bag before tossing them into the trash.
2. Generously sprinkle cornstarch over the remaining oil and let sit for about 10 minutes. Cornstarch has worked well for me, but some sources suggest you can also use baking soda, if that’s all you have on hand. (Update: Stick with cornstarch unless you have a canister vacuum; the fine particles have a tendency to clog the filters.)
3. Vacuum the cornstarch using a handheld vacuum. (Am I the only one who still uses a Dustbuster?!)
4. Wipe the surface using a little water and liquid dish soap if any oily residue remains.

Bonus tips!
• If the oil gets on your clothes, rub a little cornstarch into the clothing and let it set before washing.
• If the oil gets on your carpet, sprinkle with cornstarch and wait about thirty minutes for the cornstarch to soak up the oil. Vacuum excess cornstarch and — fingers crossed — the stain should be gone.

Never wash rags soaked in oil They could catch fire. If you use old towels to clean up a cooking oil spill throw them out
Can I wash my clothing that I spilled the oil on?
i think a quicker and more effective way, is to gather it up using a squeegee and a dustpan. only after you’ve gotten the majority of it that way, use the corn starch and rag method.
Thanks, mostly! Your article helped, except for one problematic part.
The Internet is full of warnings that say: “Do NOT vacuum up baking soda.” The particles are too fine. Will clog motor, filterways, etc; could well render vacuum unusable.
I had knocked over half a bottle of vegetable oil, but it spilled onto a linoleum floor. Found and read your article. So used paper towels for the pools. Then sprinkled baking soda (had no cornstarch) onto floor. Waited 15 minutes.
Then cleaned off oil-bonded baking soda particles with dustpan and brush (aarrgghhh my bad knee), then finished with more paper towels.
Worked well. Took at least 45 minutes though.
All because Stop and Shop brand vegetable oil plastic cap tore when I first tried to open it. And a month later, turns out the paper-towel-and-cling-wrap plug that I fashioned for the spout, before putting the bottle up in the cabinet, couldn’t survive a fall … Wish they made an all-purpose, adjustable-size sealing cap for times like these.
