I got to work today and where I’d parked yesterday there was a puddle (fairly normal, it takes a couple of days to dry up underground when the rain eventually stops here). However there was a slight blue tinge to the water. I smelled it and although I have a blocked nose, it smelled more or less like filthy floor water. I’ve checked the fluid levels and both power steering and coolant are at max as I topped them up in summer. It COULD be washer bottle related as I refilled it the other day but it’s on the wrong side of the car for that (although fluids do tend to move about a bit).

Could it be anything else?

does it feel oily/slippery between your fingers?

tbh, with a works car park it could have come from another car couldn’t it?

Only way to be sure it’s you is to put a big sheet of card under the front (Assuming that’s where the engine is!) and and see what’s on top of it once it’s been stood a while.

Condensate from the a.c.? Not normally blue but maybe mixed with a little oil or screenwash

WKD leaking from the glovebox?

A pensioner with a blue rinse was hiding under your car, waiting to pounce on you to squeeze your cheecks.

Lack of bladder control from a passing Smurf?

So my WKD and pensioner foam parties in the garage might have been the cause eh? You learn something every day.

I’m guessing its just rainwater combined with cack-handed washer bottle refilling given the answers

Run over Mr Bump (it happens quite a bit)?

Mr Smurf has had a wee

someone else parked there between you leaving and you arriving back? maybe filled their washer bottle up? spilled some?
have a look when you get back to the car later. if its got bigger its from your car. if it hasn’t then it either wasn’t from your car or whatever it was is now empty.

add-blue? (no idea if it’s actually blue, or if your car is diesel and new enough to have a tank of it).

What he said ^

Adblue is colourless liquid.

Dropped your raspberry slush puppy?
