Lesson learned
 

Today I opened a kit for a crib quilt and discovered a noticeable black greasy spot in the center. Now if I had just purchased it, it would go back to the store with the receipt, but I’ve had it for at least 2 years and I don’t even remember where I bought it, much less have a receipt. From now on, I will open any kits when I get home and make sure this doesn’t happen again.

not only for 'spots' but to make sure all of the parts are included.

I hope you are able to get that greasy spot out.

I'm so sorry this happened to you! Can you work around it or could you applique something over the spot?

That's a good lesson to learn. I splurged on a Derrick Lockwood kit several years ago. Life got in the way and I didn't open it right away. When I did I found that one of the fabrics was not included. Bummer. Looking for something to replace it.

I have only had one kit. It was all there and no spots. Hopefully you will get the spot out.

I think there are more and more stores that buy returns and seconds and "lots" and then repackage them and sell them for new. I bought a set of bathroom rugs with the cardboard "packaging" stapled to it, holding the two rugs together. When I opened them up at home, there were huge black grease stains on the rugs. Hidden by the carefully placed packaging. Back to the store for a refund!

Try using hydrogen peroxide with some Dawn dishsoap. I have used this and haven't found too many spots it will not remove. I keep a small bottle of about 1/2 c. with 1/2 t. dishsoap in my laundry room and just spray or squirt it on the stain i want to remove, use small brush and then wash. Sometimes it will come out and I don't have to wash it. This solution has removed blood from white sweater so it might be worth a try.

Try soaking the stain in a strong solution of OxiClean. I have had good results. You may have to leave it overnight or even do it a second time, but I think you will get results.

That was the time to try BIZ. It is a bleach, but not a chlorine bleach. It gets out stains but doesn't fade colors.

Sorry you had this happen.
I also learned about kits. I bought one from Craftsy and a lot of fabric was missing. They promptly sent me another one but there was still fabric missing. I gave up after the second one. I'll just fill in with my own.
I ended up with a lot of fabric but still it kind of bugged me.

We've found this also applies to produce--so many of the tomatoes, etc have little stickies on them now and they are placed on the bruise or imperfection.
I also have the habit of not opening packages right away--give them a day or a few--good advice to open right away.

For successful grease removal Dawn dish detergent has always worked well for me. Straight Dawn, let it sit, then brush the stain. Here's hoping that your stain will come out...

My sister showed me a trick for getting diesel fuel out of fabric. Since you have “mystery grease, give it a try? She buys Crest brand toothpaste (must be the all white paste). With an old denture or tooth brush, or even a stiff nail brush scrub the toothpaste into the stain from both sides, and about 1/2 “ around the outside of the stain as well. Let set for ten minutes then rinse under hot running water, and machine wash with laundry soap. An old truck driver showed her that trick. It is worth a try.....? You can try it several times, but remember, no dryer until the stain is completely gone. Might just save the fabric. ( I watched her take diesel fuel and grease out of Khaki colored shorts of her hubby’s so I know it can work)
