Managed to clean the inside of a coolant expansion bottle? If so what did you use

Cheers Mik

 

jetwash and some degreaser.
also put some degreaser in it and some small pebbles/stones and keep shaking it to loosen some of the hard to reach section!! then its just a case of shaking all the stones back out!!

 

ice cubes and salt also work and shake it, then put it in the dishwasher,

 

Rice and washing powder. Shake like fook and rinse!

 

mine was manky and nothing would shift it..i tried some stuff called limelight from tescos with vinegar..that shifted quite a bit of cack but i guess it depends how dirty it is to start with..you could try brick acid as ive used that to clean other stuff up before
