Why Dish Soap Damages Car Paint
Dish soap and laundry detergent are strong degreasers. One wash will not destroy your car, but weekly washing with them removes every layer of wax and sealant, leaving bare clear coat exposed to UV. In Jamaica's sun that means fading, dried-in water spots and a chalky, oxidised finish within a couple of years — exactly the dull look you see on so many older cars. Repainting a faded car costs far more than a bottle of proper shampoo ever will.

What to Use Instead: pH-Neutral Car Shampoo
Car shampoo is pH-neutral, so it lifts dirt without attacking wax. It also foams heavily and adds lubrication, letting grit slide off the paint instead of being ground into it — that lubrication is what prevents the fine scratches and swirl marks you see under sunlight. A capful or two in a bucket is all you need, so one bottle lasts months.

The Two-Bucket Method and Microfiber Mitt
Use a soft microfiber wash mitt, never a rag or sponge that traps grit. Fill two buckets: one with shampoo mix, one with plain water. Load the mitt from the soap bucket, wash one panel top-to-bottom, then rinse the mitt in the plain-water bucket before reloading with soap. The grit you just wiped off stays in the rinse bucket instead of going back onto your paint. Wash top of the car first, dirtiest lower panels last.

Drying: Microfiber Towel, Not an Old T-Shirt
Old t-shirts and rags leave lint and fine scratches. A large microfiber drying towel soaks up water fast and glides safely over the paint. Blot or drag it lightly — do not scrub. Drying matters in Jamaica because our hard water leaves mineral spots if the car air-dries in the sun. Finish with a coat of spray wax every few weeks to rebuild protection.
