I picked up my car from the dealer today after having some routine maintenance done, and noticed a spot of clear liquid on the passenger's seat. Thinking it was just water, I wiped it off and drove home. For some reason now the spot where the liquid was has turned lighter than the rest of the seat. It's way too noticable for me to just overlook, and it hasn't dried off after almost two hours. The leather on that spot actually feels different and kind of damp if I run my finger over it. I've tried cleaning the whole seat but it's done no good, and unfortunately I have no idea what the liquid was that caused the damage except that it looked and felt like water. Is there anything I can do for a spot like this or do I need to have a professional fix this?
