Hi all,
First post, apologies if there's been previous threads covering this topic, I did a quick search but didn't find anything pertinent to my situation.
Picked up a Mazzer Major the other day for $120 (pretty chuffed by that). Clearly well used but not well looked after. Motor still runs and unit complete (besides the missing doser lid). Serial number looks like its maybe a 2004 model, with micro switches that I plan to bypass.

Celebratory Zinger burger for scale. My recently retired BES900 in BG (scored an Expobar Office Control)



The thing smells like an ash tray and was caked in black coffee grime. Guessing the heat from use roasted the remnants of previous coffee grounds to ash.
Have broken everything down to its components and plan on getting new burrs, but unsure what to use to remove the oils and scents that have built up in the internals, as most places warn about using water.
QUESTIONS:
1) Would bicarb, white vinegar or isopropyl alcohol (or a combo of these) be suitable in deep cleaning the internals?
2) What would be suitable in leaching out the smell in the plastic of the hopper and doser window? A good soak in some kind of solution?
Was playing with the idea of making up a solution using the above mentioned chemicals, soaking paper towels in the solution and wrapping the insides to steep them for a while, before rinsing and repeating. Just want to avoid any potential for corrosion.
Any help would be greatly appreciated! Will post photos of the restoration asap.

I used a toothbrush and have taken all screws out where possible, gotten in the nooks that I can, and given good wipe down with paper towels, but have avoided using any liquid for fear of doing damage. Will try the damp rag and dry with a hair dryer perhaps?
