Waterless vs steam in basement parking: the method decides the price
Most UAE apartment dwellers meet mobile washing in a basement, and basements dictate method. Pressure washers and hoses are out: there is no drainage, buildings prohibit them, and municipal rules across the emirates treat wash runoff in shared parking as an offence. That leaves two legitimate technologies — waterless and steam — and they are not interchangeable.
Steam sits a tier up, usually AED 70–120 for exterior and interior. Low-moisture vapour lifts dirt with heat rather than friction, uses a few litres of water per car, leaves no puddles, and doubles as an interior tool for vents, fabric seats and light stains. If your car lives in a basement, waterless for routine visits with steam every fourth or fifth booking averages out cheaper than steaming every time.
