Most paint swirl marks don't come from road debris or harsh weather. They come from washing. A contaminated sponge dragged across a hood, a stiff towel pulled over slightly dusty glass, or a squeegee working across a panel that still has grit on it -- the drying process alone accounts for more clear coat damage than most owners realize. Larry Kosilla of AMMO NYC, detailing professionally and demonstrating on a Porsche 911 convertible in this episode, walks through his complete maintenance wash routine for the weekend driver: wheels first when it's sunny (to avoid soap and water drying on paint while you work), paint next using straight-line towel passes with clean towels swapped before contamination transfers, then interior. The full process takes 30 to 40 minutes if you stay focused. Some people spend 45 minutes on a single wheel. Both approaches are fine.
For EV owners specifically, the routine carries a few considerations worth naming. Regenerative braking significantly reduces friction brake use, which means less brake dust accumulation on wheels over time -- one genuine low-maintenance advantage of the drivetrain. EVs are heavier than comparable ICE vehicles, though, which increases tire wear rates and puts more road contamination into wheel wells and lower body panels. Pressure washing near the charging port door requires care; most manufacturers recommend keeping direct high-pressure streams away from the port opening itself. More broadly, EVs carry higher purchase prices than their ICE equivalents in most segments, which makes paint and interior upkeep a stronger financial argument: a car that looks after its finish holds residual value better and costs significantly less to correct later than one that needed a machine polish after three years of improper washing. The 30-to-40-minute weekly routine Kosilla describes is the cheapest form of vehicle protection available.
Kosilla's system divides into three areas. For wheels: rinse first, apply wheel cleaner to the wheel, caliper, and tyre, work a large brush from 12 o'clock in one direction, use a smaller lug nut brush in tight spots, wipe behind the spokes with a folded towel, agitate the tyre sidewall with a stiffer brush to clear old dressing, then rinse. One wheel start to finish before moving on. For paint: knock off heavy dirt with water first, then wash in straight lines from top to bottom using a plush microfibre towel, folding to a clean face as it loads up. He uses one wash bucket with multiple clean towels rather than the traditional two-bucket method; the towel is replaced rather than returned to the bucket once it picks up dirt. The drying step, which Kosilla calls the most neglected part of any wash, uses a damp microfibre towel with a lubricating product applied to the paint surface first. Dry microfibre on a wet car with any remaining grit creates scratches. Lubrication prevents that. Interior gets leather cleaner in three formats depending on how dirty the surface is, a crevice-tool vacuum for carpets, and glass cleaned last.
Bottom line: Kosilla's process is repeatable and structured, which is exactly what makes it effective over time. Two principles drive the whole thing: always lubricate when drying, and treat the drying step with the same discipline as the washing step. Everything else is secondary. For anyone heading into summer driving with a car they care about, this is the most useful hour you'll spend this week. The technique works on any vehicle. EVs, which tend to cost more and depreciate differently, have even more reason to stay clean.
