1 one of my first lessons as a new nurse, how to use blueing in the whites. You always want to look clean, fesh, and sparkling!

2 Cool. Never heard of the stuff and it sounds like something that I would want.

3 Laundry? What's that? Is that something new?

4 Doubtful - there is no control over how much blue dye is released into the wash water with blue jeans. When they're new - it's often quite a lot - which would make white clothes look blue... later there is none which defeats the purpose. (Not to mention - I have no idea if they are the same kind of dyes... bluing may be very different from blue jean dye) Also, white clothes tend to be made from more delicate fabrics - so washing with blue jeans will cause them to wear out faster than normal even if the "bluing" effect does work. And some could even be ripped by catching on the zipper. It'd just be cheaper and more effective to grab some Mrs. Stewart's - which has been around for as long as I can remember - my mom used to use it.

5 Laundry: Something your wife is supposed to do, but she fucks it up, so you end up having to do it yourself so it gets done correctly...

6 Bluing actually has a high concentration of UV brightener that is mostly responsible for the the 'whiter' whites. It's not just a plain blue dye. (Many laundry detergents contain the UV brightener in smaller amounts, to attempt to achieve the same effect.) I learned the hard way about UV brighteners and fabrics when shooting weddings. Cheaper wedding dress fabrics use a lot of it to appear whiter. Unfortunately, colour film records UV quite strongly as blue. A really cheap wedding dress could be pretty much impossible to colour correct, without throwing off the colour balance of the rest of the image. I even had to wash the sheets I used as light diffusers in soap, rather than detergent, as it doesn't have the UV enhancers. P.

7 Washing whites with blue jeans or even blue clothes will make your whites turn blue. Trust me. That was an educational experience I didn't need to learn.
