Alloy casing cleaning
Posted: Mon Jun 30, 2025 2:33 pm
Cleaning the alloy engine casings on my 900A4 , I have done the cam cover with gunk then soap and water then a coating of Fertan H102 Aluminium Cleaner then Solvol Autosol and wire wool , them final polish with Solvol only.
Trouble is there are still blackish markings etch on the alloy, I am thinking Vapour Blast is the answer but any ideas would be welcome.
