My question is what substances can ultra-violet protection (UV) protect? It protects against the oils on your hand and against the sun damage on some surfaces. I am interested in this because I like and collect baseball cards and want to see how good this UV protection is on the cards.
The materials I am using to test this are: laundry detergent, hot water, alcohol, vinegar, paper, and soda. I plan to put the cards into the liquids and observe what happens.
My hypothesis is that the card coated with UV will stand up to all liquids except alcohol, soda and vinegar.
| Soda | Vinegar | Hot Water | Detergent | Alcohol |
| 1/4 of the card got crusty and the picture peeled | got crusty | card got flaky | corners of the card split and got a film on it | corners of the card split and the ink blurred |
Conclusion: My conclusion is that from the tests I did I
can't tell if UV is tops. I will have to retest and set up the experiments in a
different way.
