UV light

[Silverballs]

Hola you all! 64k question...What UV light works best for these old white plastics? Consistent sunshine here is not due back until Spring here soooooo

Not sure. But theory would say a SAD light should be the same frequency. But I'm sure the web is awash with retrobright tips.

For what it's worth, I made a UV lightbox using a shoebox and the light board from a gel nail polish UV dryer.

I picked up the dryer at Goodwill for a couple of bucks. Took it apart and removed the lighting board and attached to the lid of a shoebox.

It works fairly well, but does take longer to turn the yellowed plastic to white vs. putting in the sunlight.

What type of UV light it is? I don't know, but it does work.

I’m having the same issue past few days; tomorrow will be sunny though!!

As a science experiment, tonight I figure I will see what my son’s 100 watt LED blacklight will do with a yellowed part with Retrobright. Will check it in a few hours and see if it’s comparable to the sun’s effects!

It’s a very strong blacklight!

5 hrs under the blacklight helped a little bit; but not compared to the results the sun gives is my observation/conclusion with this experiment. I’d just be patient and wait for a sunny day.




Maybe if left for 24 hours under the blacklight might get better results

A few more hours and I believe you would of had it.
