Tuesday, May 29, 2007 Cleaning Light Bulb Filaments Question: How do you clean oxides from light bulb filaments? Answer: When cleaning oxides from light bulb filaments our recommendation is 8% Citrajet for a contact time of at least 3 seconds at about 140 deg F. In principle, every 10 deg C you go up, doubles the cleaning speed. At 185 deg F, you would be roughly 20 deg C (Cleaning Light Bulb Filaments)
