Oil On Papers

[EastCoast]

All,

 

My daughter spilled some choji oil on some NBTHK envelops. I was able to get the papers out before is soaked through; however, I am left with envelopes with ugly oil stains.

 

I am sure I am not the only one who has had this happen. If this happened to you, or a "friend", can you please let me know what you did to get the oil out?

 

Thanks in advance!

Found this. I haven't read it yet, so have no idea if it will be useful.
But looks like a comprehensive study

Brian,

 

Thanks!

 

I tried several things. What ended up working was packing the envelope full of napkins  then using a heat gun over and around the spot in a fan pattern. I experimented with different temperatures and found that 440F was the sweet spot. The oil was absorbed by the paper towels due to the heat exchange. There is 0 evidence of a spill and no discoloration or damage at all. I hope this information helps anyone that may find themselves in a similar predicament.

 

Best,

James

I am not sure that I would be terribly bothered by a spotted envelope. I like idea of using paper napkins. Certainly that would be an easy start, the but - especially since it was just on the envelop - I'd try Fuller's Earth. I have used it to remove other oil stains on paper and found it effective.

Or perhaps plain old talcum powder usually used for a baby's bum...
