corrosion from blue -20F washer fluid

I wasn't really sure where to put this, so if it gets moved I'll know why lol.

Has anyone else had this issue?

I ran blue -20F washer fluid through my FJO water injection kit for a few years, and I was injecting it right around where the power steering pump is. Overall it was fantastic, and I noticed when I broke the engine down that for once I didn't have little cracks next to the spark plug holes on the inside of the housing.

However, I did notice deposits in the throttle body, like a blueish-white powder from the fluid pooling and evaporating, along with some pitting over time. Also, it got into the threads of the air bleed screw and seized the screw. I ended up breaking the throttle body trying to get that screw to move. I replaced the throttle body and haven't run WI again until I figure out a solution.

For a while now I've been using the washer bottle. I've thought of having a separate tank made and getting a new washer fluid bottle, because I'd like to keep the wipers and fluid functional. But I'd also like to just keep using the bottle. I'm planning on starting to mix my own water/meth and see if it still leaves deposits. I'm also wondering if I can use that mix on the windshield so I can keep using the washer bottle.

Does anyone have any experience with using a homemade water/meth mix as washer fluid and/or have issues with blue washer fluid or homemade water/meth mix leaving deposits and corroding anything?
