🧪Spray Bottle

Spray bottles are the unglamorous backbone of every detailing kit — dilute concentrate cleaners, decant quick detailer, mix custom interior cleaner. Cheap ones leak, clog, or get chemically attacked by the very products you're spraying. Get chemical-resistant bottles (HDPE or PE) with adjustable nozzles, and label them clearly — nobody wants to mist their leather seats with wheel cleaner. Keep half a dozen around; you'll fill them faster than you think.
