Use any telcum powder sprinkle on the oil stain and then iron on that it helps to remove the stain

I think eucalyptus might work but read the label

Yes I also use pure dish washing liquid and pour vinegar over that or sometimes a paste of baking soda and vinegar. The quicker you treat it the better the effect.

I have successfully removed oil stains using Aldi stain remover spray and soaker. It gets everything out and is so cheap

Dishwashing detergent is good for cooking oil stains. If all else fails, a paste of napisan and water rubbed into the stain, leave for 5-10mins and wash as usual. Repeat if needed

If we’re talking cooking oil you can rub dishwashing liquid onto the stain and then pour vinegar over that. Then wash as usual and it should come out.

Have you tried a stain remover spray?maybe soaking it over night with somd detergent it might depend on what type of oil stain it is

You could try scrubbing with dish washing detergent, rinse then put it through the washing machine. Has worked in the past for me.

May I ask what type of oil? Cooking? motor? essential oils or other oil?
