Had car washed and vaccced on Tues, on Thurs 4 yr old battery was stone dead - thought "Oh well battery is 4 yrs old" so replaced it.

This afternoon new battery stone dead. Checked volatage - 10V - put on charge - once voltage up a bit checked all lights. Rear vanity light on

Car wash (and my stupidity) cost me new battery

Ooops

Did they jet wash the engine bay?

If so its the person/company who did it that is at fault, get em to pay for the battery!
