The northeast monsoon kicks in around November on the east coast, and by December the rest of the country is getting its share of late-afternoon storms and weekend washouts. None of that is a problem for a well-maintained car, but a few hours of preparation now saves a lot of grief later. Here’s our list, in the order we’d do them.
1. Get the wipers right before the rain starts.
This is the cheapest, most overlooked monsoon-prep item. Wipers that judder or leave a film across the screen will turn a heavy downpour into a genuine safety problem. Replace blades that are more than 12 months old, top up the washer fluid with a proper concentrate (not water), and clean the windshield inside and out before the first storm.
2. Coat the windshield.
A good hydrophobic glass coating — we charge RM 180 for one — means rain sheets off above 60 km/h without the wipers having to work as hard. Visibility in heavy rain goes from “just about manageable” to “you can actually see the lane lines.” It lasts about a year in Malaysian conditions.
3. Check the door and window seals.
Rubber seals harden with UV exposure and let in cabin moisture during long, sustained rain. Wipe them with a silicone-based rubber conditioner; if any are visibly cracked or letting in water, get them replaced before the season escalates. A wet floorpan unaddressed for a week turns into mould you’ll smell for months.
4. Sort the drains.
Modern cars have small drain channels — under the bonnet, in the door cards, in the sunroof if you have one — that clog with leaf litter and debris. Once clogged, even a normal downpour can lead to water pooling where it shouldn’t. Five minutes with a soft brush and compressed air clears them.
5. Refresh the paint protection.
If your wax is overdue, this is the time. Top up with a six-month sealant if you don’t have a ceramic coating; if you do, book a check so we can verify the hydrophobic behaviour is still strong before the volume of rain doubles. Water spotting from sustained rain on a tired coating is a regular complaint after monsoon.
6. Prepare the interior for moisture, not the other way around.
Wet feet, wet umbrellas, wet bags. The interior will get damp during monsoon — the question is whether it dries between trips. Carry two clean microfiber towels in the boot; throw one over the driver mat after a wet day so it absorbs overnight. Open the windows on the rare dry morning to ventilate. Avoid leaving wet umbrellas in the door pockets for days at a time.
One bonus tip
If you can, book your annual coating inspection or your major detailing job before the monsoon hits. Our calendar fills up fast in October and November because everyone has the same thought at the same time. Earlier means more flexibility on slots, and you go into the wet season with the car already protected.
