986 boxster milky coolant

If the coolant itself is milky, you are in trouble. If it is just a film on the cap itself, no worriers. This is usually caused by moisture and condensation.

It looks at the moment it is just round the cap and neck. I have wiped it all away to see if it returns. I do not use the car very much and it sits outside. How many miles would I need to do roughly to see if it returns. Fingers crossed
Thanks for your reply
