Thanks for the additional information. I meant to ask if you used ultraviolet -not infrared. Regular 60 watt sounds even better. I will try it tonight.
Currently I am cooking a Carl Zeiss pre-WWII Tessar lens ( all metal and glass- no plastic or rubber ) that has an overall haze that I have never liked. I will report back after it has been cooked 2" from a 60 watt bulb for ten hours.
I was a bit sceptical, but this really made a difference in my 65 year old uncoated lens. It is clearer than before the cooking. I will cook another 10 hours tonight.
