Use Isopropylalcohol or Acetone to cleaning aperture blades, a comparison

In this video I will make a comparison between Isopropylalcohol 99% and Acetone, just to see what will happen with the plastic, when cleaning the aperture assembly and the blades.
Some types of plastic will melting or soften or being very brittle with the use of Acetone.

Most of the time use Isopropylalcohol 99%, because it will not damage the plastic.

The 2 bottles are actually made of PE / PP, so they will not soften.

Polypropylene is not as sturdy as polyethylene. Polypropylene is stiffer and resistant to chemicals and organic solvents compared to polyethylene. Polypropylene is pure, non-stretching and generally more rigid than polyethylene.
