Diy Aluminium Head Clean

Coke is not going to damage anything, but I would just use a strong detergent and a stiff brush....or both as I have never tried coke.

 

Basically it's the phosphoric acid that does the cleaning they used to use it (in different concentrations) in alloy wheel cleaner but stopped in favour of hydrochloric for some reason....I knew there was a reason I don't drink Coke.

 

You can always sniff the coke yourself. Lol

 

A guy I used to work with was into restoring really old Brit bikes. He used to clean alloy engine cases in the dishwasher and got very good results prior to his divorce.
No idea if the two events were linked though.

 

A mate of mine used to sell second hand engine components and used an industrial size dishwasher which was the same principle

 

I remember my Mum ruining a set of fancy wine glasses with gilt decoration in our first dishwasher due to the aggressive detergents used.

 

That reminds me, I think my dishwasher is due a service

Well, the thread was derailed anyway, cylinder head to guilt wine glasses. Gotta luv this forum.

 

Where did you get your dishwasher? Our Beco is about to die.....not sure the wife would stand for that model.

 

Trade secret TD, but one tip though, get one with small feet, they can stand closer to the sink, saves all that lower back strain. (Though a little internal support alleviates a lot of that)

 

Dishwasher gives excellent results

 

Nice dishwasher photo Andy Nowt changes

 

Cheers Keith, long time since you were on, nice to hear from you.

 

Good quality paint stripper...not the ‘new’ stuff...like original Nitromors used to work wonders, carbon n all....safe on alloy cylinder heads..I used to use it on alloy aircraft bits so no danger of damaging the alloy..leave overnight then thorough clean in hot soapy water and rinse .

 

Ethanol of either type does no harm to any cylinder head , cast iron, steel or aluminium ! But it will affect any rubber 'O' ring's or such , even after only a minutes contact!
Don't use any to flush a motor out , as it will cause any seal's in water pump and even rubber hose's to soften and swell up !!

 

She looks like she’d give a nice hand finish too...
