I'm looking for a reliable car cleaning service to thoroughly wash the exterior and interior of my small sedan. The job should include a proper wash, shine on the exterior, vacuuming the carpets and seats, wipe-down of the dash, windows, and mirrors, and a quick interior deodorizing. I’d prefer eco-friendly products and a fluid contactless payment option if possible. Location is in central London, and I can be flexible with timing on weekdays. Please let me know if you can handle stubborn stains and any additional services like wheel cleaning or rain repellent.
