You know those receipts you get from stores (like Costco) that are on thermal paper and fade?
I kept trying to look at one that was left in the car and had faded but gave up.
Then I remembered that a copy of the receipt is stored in my Costco account and will print quite nicely at home. They only go back a few months for me because they had to change my card number. They were able to pull up old receipts at the store for me.
If you Google it, there are several methods to restore faded receipts: heating the paper, Photoshop, etc. (in case the store can not retrieve it from your account).
This is a much better way to look up recipes. I believe Costco receipts [and most other receipts too] are printed with a chemical that has been linked to cancer- BHT I think.
