Do not pump the brakes. You will need to get all of the contaminated fluid out and refill the master cylinder.
Change oil and filter
did u put a little bit or alot? if its a little use a turkey baster to suck it out
doesnt matter they work in either you are ok just dont doit unless emergency
The first thing you should do is remove the master cylinder so you can dump the brake fluid reservoir out. If you have used the brakes, it is a very good idea to get the entire brake system bled and replace all the brake fluid.
Take off the reservoir & flush it out with hot water to get the oil out. If you drive it it can go through the cooling system and it may distort rubber seals etc. If it's a very minor amount it might not be an issue but flush it to be safe.
go to a mechanic immediately
Do not operate the washer. Remove the washer fluid reservoir and flush it with soap and water until all traces of antifreeze is gone.
go and hve the power steering system flushed
You need to remove the washer fluid. You can siphon it out, or remove the power steering reservoir and dump it out. If you haven't had the car running , you may be able to absorb it out with a rag since it is probably floating on top of the power steering fluid. The problem with washer fluid is that it is not compressible and will cause poor steering reaction when it enters the steering pump. It may even cause a loss of steering.
The 'horseshoe' is a depiction of a reservoir, probably your wiper reservoir, but possibly your radiator reservoir, which should be about half-full when cold.
Moisture can be damaging for the balances, especially the electronic balance. Therefore, liquids should never be poured in the near vicinity of a balance.
If you are only swallowing a little, there should be no harm done.
