Coolant stains
What is the best to use wash off dried coolant stains? Looks awful on the reservoir and my very posh heater valve Evil or Very Mad

I’m in the middle of fitting a new cylinder head which is the reason why the coolant has discharged Rolling Eyes

I’d probably go WD40, and leave it on ten mins and then wipe off most excess..

I think brake cleaner might be a bit strong for the anodised coating.

Will it not come off with just soapy water? TheThunderRolls🇬🇧🇺🇸
