all the brackets,alternator,cruise control box,PCM have corroded.
I would like to clean it all up. I did some with soda blasting where it was
easy to get to,just wondering if theres a spray on wash off product that
works. I tried 2 different brands of A/C condenser cleaner/brightners and had so so results.
Also whats best to seal it up,after its cleaned.

engine degreaser not unlike the kind most restaurants clean their cooking grills with at the end of the day. You spray it on let sit maybe 30 seconds spray off with a hose. Itll get oil, power steering fluid, tranny fluid, hydraulic fluid, water residue and that nasty white film left by radiator fluid. The more older the stain the most likely the longer you might have the chemical sit on that spot.
5$ a can last time I checked

Super green stuff works great. I use it at work and it works great. Spray on and rinse off. A pressure washer works well if you cover up any important accessories like the alternator.

Here's what I use for aluminum corrosion, just a small soft stainless steel brush. Just don't go too crazy when you are brushing it off if you want to keep the factory look.

Aluminum Brightener. Mix it 50/50. Is acidic based, but I use it all the time at work.
You can get it at O'Reilly's. Safe on Chrome as well. We use it to clean valve covers,
timing chain covers, heads, anything aluminum. Spray on, spray off.

This^^^^ Maybe use a fine scotchbrite pad with it and it will be clean.
