Washing your plate is important!

but thing is i believe it does leave a film on to the surface of being cleaned, sorted

Edit, A mirror doesn’t fog after being cleaned with Fairy detergent (or similar dishwashing liquids) because the detergent creates a thin, invisible layer that disrupts the formation of water droplets.

That is from chat GPT, do what you wish with the info, but would not say for a fact it wont create a film on surfaces.

And still, it is a good way to keep your plate clean, even if it leaves that invisible film, if you se a film, something is not right.

Edit 2.
PBW contains powerful detergents and oxygen-based cleaners that thoroughly clean surfaces, leaving them free of oils or residues. This super-clean surface minimizes areas where water droplets can form and cling, reducing fogging. However, PBW itself is not specifically designed to leave an anti-fog layer like dish soaps might. Instead, its effectiveness would depend on how clean it leaves the surface.

Will try it after the print!
