Flush Old Fork Oil Out

[JoeC]

Replacing the fork oil in my 1150 (took forks out and inverted rather than use drain plug) but I can see lots of gunk in the bottom.
What is best to use to flush the forks out before refilling with clean oil?

Ta.

In case anybody asks I shall being refilling with 10w and 470ml in each fork.

Paraffin? Petrol? brake cleaner ?

Are the suggestions above likely to damage the inside of the forks?
Any thoughts or further suggestions?
Might just go down the warm water a washing up liquid just to play safe.

Why not use fresh oil to flush out the muck?

 

[ELIMINATOR]

As fork oil is cheap, why not refill, ride, then drain again, this time using the drain plug. As this gunge has settled in the bottom of the fork, then draining through the drain plug will push it out, rather than inverting the removed forks.

You are joking right??

Change the oil, go for a good ride, change it again whilst everythings still warm.

Was worried about anything attacking/rotting the plastic tube inside the forks.

 

[cookie]

perhaps stick to brake cleaner then.

In the end used meths to flush out and brake cleaner to tidy up.

No. I am guess it was a slip of the tongue.
