How do you clean your lab glassware after formulating with sunscreens?
This has been a difficult job that takes several days… It looks like powdered ingredients as Parsol (TX and ZX) once heated stick to the glass and become extremely problematic. I can’t clean the containers easily, the remains of the formulation hardens and even when I heat water to make the glass hot, it takes a lot of time to clean because the residues spread through all the glass, leaving a white trail that makes me really mad. :pensive:
The only solution I found was to leave the container immersed in water for a few days until the detachment becomes easier, but I think there must be a better way to solve this. There needs to be. :sweat_smile:
Thank you in advice! :blush:
