BYD Seagull Interior Deep Clean: Don't Flood the Carpets
The BYD Seagull manual prohibits washing the floor with water or letting water reach electrical parts. What to ask a valeter, and when to get help.
BYD Seagull interior deep clean: soaked carpets can't be fixed with more water
Scope: China-mainland 2026 Seagull; official website file 260317; PDF p. 317, "Interior cleaning"
A clean look isn't electrical safety
The manual prohibits letting water run directly onto the dashboard, the floor or nearby electrical components, and prohibits washing the vehicle floor with water. Stains on the carpet tempt people to rinse them with lots of water, but cleaning the interior also means keeping materials and electrics dry; a surface stain disappearing does not prove that no water got into the area underneath. [1]
Choose a service that respects these limits
When booking an interior clean, tell the provider clearly that this car's floor and electrical areas must not be washed with water, and ask how they control the amount of water and keep the carpets dry. For carpets that are already soaked, a valeter cannot replace a vehicle inspection. Where water has got in or electrics are behaving oddly, the workshop should decide, rather than assuming it is safe because there is no smell after drying. [1]
Stop promptly if something goes wrong
If liquid gets near switches or wiring during cleaning, or an electrical fault appears afterwards, stop using the equipment concerned and contact professionals. This article gives no seat removal, under-carpet wiring drying or electrical reset steps; these areas may involve safety systems, so household carpet-cleaning experience cannot simply be applied. [1]
