How to Deal with Mold on the Car Roof?

[LiamDella]

First, lay the seats down and cover them with a towel or seat cover to prevent contamination from water or cleaning agents dripping from the roof. Fill a spray bottle with a diluted solution of water and cleaning agent, then spray it onto the car roof. After the cleaning agent starts to foam slightly, gently scrub with a soft brush using light pressure. For dark-colored roofs, to check the level of dirt, simply wipe the surface lightly with a clean, damp towel.

Roof mold is quite common, likely due to excessive interior humidity or rainwater leakage. When dealing with it myself, I first gently wipe off the mold spots with a damp cloth, then scrub with a solution of white vinegar and water (vinegar kills bacteria) to avoid damaging the roof material. After cleaning, immediately use a hairdryer or place the car in a ventilated area to dry completely, otherwise the mold will return. Also, check if window seals and sunroofs have aged or developed gaps, as these are the root causes of leaks. Prevention is simple: ventilate the car by opening windows after parking, or place moisture-absorbing boxes inside. During high-humidity summers, avoid parking in damp areas.
