Dry & Exterior Finish: the full procedure
Dry the vehicle fully and finish exterior touchpoints so the car leaves spot-free and the customer’s first impression is a clean, dry shine.
- Applies to: Dry/finish attendants
- Frequency: Every vehicle (finish stage)
- Scope: Covers manual drying and exterior finishing after the wash. Any finishing chemical (spray sealant, tire dressing) defers to the product label/SDS; air-dryer and equipment operation defer to the manufacturer’s manual.
What you need
- Clean microfiber towels (color-coded by zone)
- Drying air blower/wand
- Tire dressing applicator
- Glass towel
- Towel-rotation bin (clean/used)
- Spray sealant if offered (per label)
The procedure, step by step
- Start with the glass and mirrors — Dry windows, mirrors, and the windshield first while towels are driest, working top sections to bottom.
- Dry the body top-down — Move roof, hood, trunk, then sides and lower panels, folding the towel to a fresh face as it loads up with water.
- Hit the hidden water traps — Wipe door jambs visible at the edge, mirror backs, door handles, and the rear hatch lip where water beads and drips after the customer pulls away.
- Use color-coded towels by zone — Keep glass towels separate from body towels and never use a body or wheel towel on glass — swap, don’t reuse across zones.
- Apply tire dressing cleanly (if purchased) — Dress tires with the applicator per the product label, keeping dressing off the paint and off the wheel face; wipe any sling immediately.
- Final spot check in good light — Walk the vehicle and check for water spots, streaks, and missed sections; re-dry any spot rather than leaving it.
- Signal the customer the car is ready — Make eye contact, confirm the finish, and thank them — the handoff is part of the finish.
Quality check before you finish
- Glass dried first and streak-free
- Body dried top-down with no standing water
- Door handles, jamb edges, and rear lip wiped
- Color-coded towels kept to their zone
- Tire dressing applied without sling onto paint or wheel face
- Final walk-around done in good light before handoff
- Customer thanked at the finish handoff

Frequently asked questions
Why dry glass before the body?
Glass shows streaks and water spots the most, so it should be dried first while towels are at their driest and cleanest. Working top-down from glass to lower panels keeps runoff from re-wetting finished areas. Color-code towels by zone so a body or wheel towel never touches glass.
How do I keep tire dressing off the paint?
Use a controlled applicator rather than spraying freely, keep dressing on the tire sidewall and off the wheel face, and wipe any sling immediately before it bakes on. Over-application leads to sling onto rockers and complaints. Follow the dressing product’s label and SDS for safe use and surface compatibility.
