Card bleaching is an attempt to use chemical agents to clean, brighten or whiten a card. Bleaching can hide or mask stains, remove the naturally harsh toning of a card or clean up a dirty border or section. Just because the word “bleaching” is used to define this type of alteration, it does not necessarily mean that ordinary household laundry bleach is used in the process. Also, the term bleaching does not always pertain to whitening an area. Chemical solutions can be used to revitalize a card and make the colors appear more vibrant. This is especially true with lighter colors. The solutions can all but eliminate years of natural wear, discoloration and dirt. |

that baseball cards would have become such a huge business that we would need to worry about this stuff. Thanks Kevin for your knowledge. I, for one, enjoy reading this stuff. |

For whatever it's worth, SGC returned (multiple times) to me two T206 cards that they claimed had been bleached. They also explained they used the "smell" test and it failed that, too. Those cards were certianly whiter and cleaner than they should have been. |

If someone is really serious about detecting ANY chemicals added to cards, they should invest in a mass spectrometer. It is a non-destructive test and will tell you the exact composition of the item in question (provided the card is not inside a holder). We have several where I work and they aren't cheap. |

A mass spectrometer (MS) is destructive although it requires almost no sample. The hassles of detecting vapors emitted by a card by MS would require a decent amount of effort. I'd say you'd be better off using Kevin's tips to spot bleaching and spending the $75k (or so depending on what you need) price of the MS on more cards. |

"Have you attempted to get each of these alterations through the grading companies? bleaching, coloring, pressing, etc? |

"However, talking to the Material Scientists where I work, they thought of several ways of getting around this such as taking a single fiber from a freyed corner or gently wiping the card with a damp swab (wetted in distilled water) and analyzing the swab for chemical residue." |
