I restore shoes, & we have this method for oxidizing the translucent soles to get them to look new again.
The process is: clean surface Apply 40 Volume peroxide cream Place under UV Growlight.
I follow the process. I get the results. But I don’t actually understand what happening. What does the peroxide & passing uv do to remove the yellowing? Can I concentrate the peroxide for more thorough & faster results? How big of a factor is the UV light? If I hade to make a compromise in either direction, would I be better off with more concentrated peroxide cream or more powerful UV source? I want to really understand what’s going on so that I can improve the service that I provide. Thank you for any time you put into this question.
