Cleaning donor Parts

[Bonzo]

Personaly, I never use anything else but Jizer

Jizer will wash away with water nicely & will air dry very well.

Never been a big fan of Gunk .... Mind you I have not tried it for years & the formulation may have changed since then

Parafin ( Kerosene ) Used to be popular with us older folks


These day's, I remove the worst of the grime with a scraper, brush well with Jizer & leave for 20-30 mins, give another good brush with Jizer & then give it a good going over with the pressure washer ( A garden hose will do ).
When I am in a hurry, i'll blow dry with compessed air.

If you are ultra lucky & have access to a steam cleaner, with the right detergents parts will come out super clean
