Should my battery look like this?

Serviced the mk3 1.6tdci today.  battery inspection revealed this (photo below). Is this normal? No issues from the battery to date.

Get a kettle of hot water and wash it off.

I'm doing well out of your garage store (made use of the oil + filter + brake fluid today!) 😄 Is that stuff a sign it's on it's way out?

That's the battery acid leaking out, may be charging a bit to high a voltage occasionally or battery starting to become faulty. I would wash it off with boiling water then when it's dried off , take bracket off , remove battery and more boiling water in the battery tray to wash it away.  The bracket may have had the paint corroded off. Give it a spray with some paint . I would then refit battery and bracket. Just keep an eye on battery in a months time to see if it's furring up again. Then you may need a new battery.

I even did brake fluid change on my focus , thats the first in 5 years. Also full brake check/adjustment and air con service/recharge. Couldn't be bothered to do oil and filter today but was changed 4/5 months ago.

Thanks Ian, I will do that.  Hopefully I won't need a new one...£126!!  Ouch..bring back the mk2 battery!  We don't even use the start stop.
