WeatherCar: Wash & Shine Guide

Wax Polish & Coat Conditions

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Detail your car with confidence. Check today's wash, wax, polish, and coating conditions based on local weather matched to your car color, parking, and products. Should you wax your car today? That depends on the temperature, humidity, dew point, UV, wind, and rain forecast — and they change every day. WeatherCar checks all six weather variables at once and tells you if conditions are right for washing, polishing, waxing, or applying ceramic coating. HOW IT WORKS 1. Set up your car profile: color (dark, medium, or light), parking type (outdoor, covered, or garage), and water hardness. 2. WeatherCar fetches your local weather and runs it through detailing-specific scoring. 3. You get a Detail Score with GO, CAUTION, or SKIP for each activity — wash, polish, wax, and coat. It takes 20 seconds to set up. No account required. DETAIL SCORE Your daily Detail Score combines temperature, humidity, dew point margin, UV index, wind speed, and rain forecast into a single number. Green means go, yellow means check, red means wait. Open the app before heading to the driveway. WATER SPOT RISK Hard water plus hot sun equals permanent spots. WeatherCar estimates your water spot risk based on your local water hardness, temperature, and UV — so you know whether to dry fast or skip the wash entirely. SURFACE TEMPERATURE ESTIMATE A black car in direct sun can be 30°F hotter than the air. WeatherCar estimates your surface temperature based on UV, cloud cover, and your car color to warn you before wax bakes onto hot paint. Upgrade to Pro for deeper insights: - Individual GO/CAUTION/SKIP for wash, polish, wax, and coat - 7-day detail planner — find the best day this week - Best window today — hourly breakdown - Protection life tracker — know when your wax or coating is fading - Water spot risk score - Surface temperature estimate - Detailing history log - Daily notifications for good detail days PRIVACY FIRST All settings are stored locally on your device. No account, no tracking, no ads. Location is used only to fetch weather data from a public API. Your coordinates are never stored on any server. This app provides weather-based condition assessments for car detailing activities. It is not a substitute for product manufacturer instructions or professional detailing advice.
