Hello, unfortunately, our lodger has left a very unsightly spot in the TG. Well, we can now go to the investigation which liquid this could be. Where the stain is to be seen, the engine is placed. I still sucked it up yesterday with kitchen roll. It looks greasy on the fingers, but smelled not really strong and certainly not to ÖL. The color is reddish and has now left a spot. It looks like a motor oil or the like. I wanted to try it today with Mellerud car oil remover. We unfortunately have to get the stain completely away, otherwise we have to pay a penalty at the delivery in January. and I really have zero bucks on it. What could it be and could Mellerud really help or is there still a housewife trick? Thank you.
