Greasy mark on bomber jacket

[shroeder]

dd has a black polyester 'silky' type bomber jacket.
It's wool wash only and says not to rub marks.
I have washed it once with soap flakes and again with colour powder, but the mark is still there.
What can I try that won't discolour it, it is her baby!

Anyone?
I tried soaking it briefly in washing up liquidy luke warm water, then washing it again in colour powder. Still with the greasy mark.

I would put some detergent on it. Washing up liquid works well. Then run your hot water until it is very hot and run the water through the area of the stain. Then wash the jacket again on the wool wash.

Sprinkle talcum powder on the stain liberally. Leave for 24 hours to absorb the grease then gentle wash in machine.
