Oil In Windscreen Washer Bottle

[Guest mcramsay]

Right so 4 years ago when I was working in my old mans garage I drained some oil out and decanted into a suitable container, this happened to be an empty bottle of windscreen wash. Obviously never got around to disposing of said oil as 4 years later my old man decided to pour a nice amount into the washer bottle on his 2014 Mercedes M class before he realised it was oil ( for the life of me I can't work out how he couldn't see it was oil) anyway, short of removing the washer bottle which is buried deep in the engine bay is there anything I can run through the system to clean it out which won't nacker the washer pump / cause the hoses to perish?

Can't you fill the container with water, wait for the oil to rise to the top in the filler neck and then suck the oil out with a syringe?

I would be tempted to run a load of soapy water (washing-up liquid) through the bottle and pipes. Protect the paintwork if poss and use a drip tray. A bit of hose pipe, down in to the bottle so that the soap gets to the bottom and forces the oil out.

+1 for soapy water.

If you can reach it disconnect the pipe from the washer jet & pump into a container.

 

But to be honest given the safety implications I'd remove the reservoir for a through clean

with a bottle brush if at all possible.

Not single , but understanding wife, have cleaned many things inc cartridge cases for black powder rifles , pistol parts , coolant o/flow tanks but not been caught mick

Harder part is getting the oil out of the lines to the jets.

I am guessing that the old man found out when he cleaned the windscreen.

Lots of fairy needed.

I was about to say, the trick is doing it when they aren't around.

Luckily he realised as he poured in a small amount, he flushed the tank but is still getting a small amount of residue on the screen!
