Exterior: This rainy days mas madalas akong mag linis ng sasakyan especially underwash, Kasi yung putik pagtugal at natuyo masmadaling mamuo ang kalawang. Mas madalas din akong mag wax para dumulas lang yung tubig sa body.
Interior: Di ako nawawalan ng uling sa ilalim ng upuan, para maabsorbed yung amoy sa loob ng car ko.
Exterior:
paint: Wax with a good quality paste or liquid wax or seal with synthetic sealnts. If you opt for the wax, do this more often, specially during the rainy season. Mga every 2-3 weeks. Sealants are more durable, so pwede na mga once every 6-8 weeks.
glass: Clean and polish, then, apply a glass treatment product like Rain X or Rain Away. Cleaning and polishing will prevent wiper chatter, and the glass treatment product will aid in preventing watermarks from occurring on the windows.
Interior: If mats get wet, AIR DRY, AIR DRY, AIR DRY. Walang shortcuts, eh. b2y's advice re the uling sounds very good. Have to try it myself.
If it doesnt stop raining or you cant clean your car but its gonna be parked... hose it out (especially the wheel wells).
If i'm about to leave the house and it stops raining, i douse the hood, roof, and trunklid with a bucket of water... Since the car is waxed, most of the rainwater beads will be washed off and only leave a few water spots/beads.
