Quoted from reynolds531:What strength solution of hydrogen peroxide are you using?
My question too.

The stuff is cheap enough (assuming the 3% formula is the right one) http://www.walgreens.com/store/c/walgreens-hydrogen-peroxide-3-topical-solution-usp/ID=prod6056573-product
3 bucks for 1/2 gallon. , for 6 bucks one should be able to clear up an F-14 dome!
Eddie, is it only good for 1 use, or can it be used a few times?
Here is a great read on the subject. One thing that caught my eye is that the author likes 6-12% solution hydrogen peroxide for best results. http://www.exisle.net/mb/index.php?/topic/59657-de-yellowing-plastic-the-stain-isnt-permanent-after-all/
Quoted from Jenk540i:Regular off the pharmacy shelf h2o2. About 1/2 bottle in a zip lock bag. Did not dilute it.
So you are saying the 3 % stuff? Looks great. I imagine if you use higher percentage hyd peroxide it wouldn't take as long. But whats the hurry anyway! 3% at Wal-mart is 88 cents a quart!
Project F-14 Dome. I was going to use the big ziplock bag at first, but it leaked. I used a big plastic cheesball container cut off and used plastic wrap on top. It took about 1.5 gallons of 3% so thats around 6 bucks worth. I don't know if it will work or not, but I will update this in a few days with results. Good or bad.
If it does work, I will do the blue and red domes too in the same solution. You can't tell the yellowing as bad on them, but I am sure its there.

Well, I was hoping to leave mine in the sun for about a week before posting. We have only had 3 sunny days here since I started this, but the results are not encouraging. Maybe some reduction in yellowing, but not much. My results were probably not quite as good as the ones from this link

Now I haven't given up hope on this de-yellowing process though. Just needs to be refined. Higher % peroxide, more intense UV, longer exposure times, adding oxy clean? All things that would likely help.
One last thing. A F-14 dome, sitting high on a back box, is exposed to smoke real bad in a bar too. It could be a combination of chemical changes that effect them so much. Not just the yellowing that plastics under the PF glass get. My conclusion is if you want a nice , non discolored F-14 white or clear dome, you better buy a reproduction one while they are available. Worth a shot tho
