Vinegar is a natural cleaner that works like a mild bleach and can be used to clean many types of materials.
Remember that the sooner you start working on the oil stain, the easier it will be to remove.
If the oil spot looks like it is getting too wet, dab it dry with a paper towel or let it air dry so that you don’t create a hole in the paper. Keep dabbing rather than letting the vinegar soak in, until the stain appears to be lifted, then you can dry the area.
Keep in mind that this method will work better the fresher the stain is, older stains may not come out completely but you can reduce their visibility. [5] X Research source
The paintbrush should be soft-bristled and of an appropriate size to dust the oil spot you want to remove with the chalk powder. White chalk powder works well to absorb grease and oil.
It’s important to start working to remove an oil stain from paper as soon as possible so that it doesn’t have time to completely dry and set.
You can lay one piece of clean paper next to the paper you are cleaning, slide it carefully over, and then lay another clean sheet on top.
Test the warm iron on a blank piece of paper first to make sure that it does not burn so that you don’t destroy the piece of paper you are trying to save. If it is too hot, lower the setting and test it again. Depending on how set-in the stain is, this method may not completely remove it, but it will get rid of some of it.
