I don't think hydraulic oil is a good alternative, tis bad for the hands (safety sheet says to wash immediately after contact with brake oil) as well as should be disposed of in the correct manner, not into the ground or waterways.
It isn't water soluble either...

I should have been more specific and said "brake fluid", this is definitely miscible with water, unless the formula is now different from when I was in the motor trade.


From Wiki:

"Brake fluid is a subtype of hydraulic fluid with high boiling point, both when new (specified by the equilibrium boiling point) and after absorption of water vapor (specified by wet boiling point). Under the heat of braking, both free water and water vapor in a braking system can boil into a compressible vapor, resulting in brake failure.[4] Glycol-ether based fluids are hygroscopic, and absorbed moisture will greatly reduce the boiling point over time. Mineral oil and silicone based fluids are not hygroscopic."

EDIT
Explains why changing the brake fluid is a long time scale service attention.

Brake fluid is nasty stuff, as Roy says it's a very effective paint stripper, ditto a herbicide. Not something you want to get caught spraying around in a SSSI like Masson Hill, Natural England will take a very dim view!

Ric - aren't you a couple of days early for doing t'owd man's candle?

Nick - from my recollection of said HMHB lyric, isn't it "Gouranga, gouranga, yes I'll be happy, when you've been arrested for defacing the bridge"?

Oh God of Sarcasm, thanks for everything...

I was quoting from a brake fluid safety data sheet...

You are indeed right AR, my memory is obviously not as good as I had hoped!

Thinking about this from some experience in bearing metal spraying, a hand held sand blaster would probably be ideal for this sort of job.
Could probably be run off a diving bottle and 1st stage regulator.

Just need to find one on Fleabay in the UK

I have something similar for use in the garage, I'm not sure it would be the best thing to use underground, it doesn't half get through the grit and makes a hell of a mess (unless I am doing something wrong). I've given up with it and gone back to using sanders!

Agree, a messy procedure but should be OK if being done in a quarry. Any dry sand will do instead of the overpriced grit or steel shot.
