Chemical Guys EcoSmart RU is the ready-to-use version of the brand's waterless wash and wax, supplied in a 473ml spray bottle. Chemical Guys states it is formulated with eco-based natural carnauba wax and hyper-efficient lubricating agents, cleans a car without a bucket or hose, and washes and waxes the paintwork in one easy step while leaving a scratch-free finish. It is suitable for paintwork, glass, plastic, rubber, stainless steel, metal and aluminium, and the maker's directions ask for the solution to emulsify dirt for 15 to 20 seconds before wiping off. It suits quick top-up washes between full detailing sessions, and pairs with plain microfibre towels rather than wash mitts or pressure washing kit.
