You can use plain soap to remove oil and grease stains before washing.
It's cheap and has worked well. Wet the stain, scrub it with damp soap, and then scrub it with an old toothbrush.
First of all, you should absorb the oil from the surface as much as possible using an absorbent.
For these purposes, cat litter is used in granules, which absorb remaining oil.
After this, the spill site should be covered with dry cement for several days, then removed and the surface washed with detergent.
Apply a small amount of dishwashing detergent to the stain.
You can also use an all-purpose surface and textile cleaning spray.
Leave the product on the fabric for 15-30 minutes.
Be sure to blot the napkins again so that no marks remain on the fabric.
Fuel oil is an oil product, so you can try to remove a fuel oil stain with gasoline.
To do this, place a cotton rag on the wrong side of the clothing.
Then use a rag soaked in gasoline to wipe off the oil stain.
After this process, soak the robe in detergent for 2 hours, rinse and dry.
