Just like mud!

[Flat on my back]

Any of you guys had success cleaning the exspansion tank of that nice brown layer that builds up? Or do you just replace the tank for a nice new spangley one! Might try a dishwasher cleaner tablet after i've seen what it does to the roasting tin! Whilst its out of the car of course!
Keep you informed of the result when it happens.

I think every one is just buying new ones at about £20+

I would be tempted to use powder bleach or some descaler stuff in a little bottle with a yellow lable (use it at work on anything that has water running or flowing) if i was going to have a bash at cleaning HTH

i tried cleaning mine at one of Greg's Garage meets and all the gunk came out but the actual plastic was stained so to get it back to looking new = new tank...

Any recommendations of what to flush the system with just before i fit all the new clean shiny bits?

Flushed mine through with a hose, the drained as much as I could and then refilled with VAG coolant and De-ionised water when I changed my radiator.

The only way I know how to get rid of this is FORTE BOI DEGREASER works wonders,when you drain the cooling system it comes out like milk(very usefull for K series Rover headgaskets and VW oil coolers which burst).
