Meguiar's G10464 Deep Crystal Car Wash - 64 oz.

Road grime, dust and traffic film build up on paint between washes, and a harsh detergent can strip the wax layer sitting underneath while it lifts them. Meguiar's G10464 Deep Crystal Car Wash is built around a pH neutral formula for that reason: it lifts loose dirt and surface contaminants without cutting into existing wax protection, so a fresh coat is not required after every wash. It produces a lasting suds layer that carries debris away from the panel, and it rinses clear rather than drying into streaks.

• 64 oz bottle, model G10464
• pH neutral, wax safe

Note that this is the shampoo only. Wash mitts, buckets, drying towels and wax are sold separately.

To get the most out of this wash, dilute it into a bucket of water before introducing the mitt rather than applying it directly to the paint. Start on the roof and work downward panel by panel, rinsing the mitt frequently to avoid dragging grit back across the surface. A second bucket reserved for rinsing the mitt keeps contamination out of the wash solution. For routine maintenance washing, a small amount of product goes a long way, which makes the 64 oz size practical for a home detailer who washes weekly or bi-weekly over the course of a season rather than someone making a single purchase for one job.

Store the bottle upright in a cool location away from direct sunlight and freeze-thaw cycles, which can affect liquid car care products generally. When comparing car wash shampoos, the pH neutral label is the primary distinction worth checking if you have coated or waxed paint, since some budget options use higher alkalinity to cut grease faster at the cost of protection. This product suits owners who maintain a regular wash schedule and want to preserve an existing wax or sealant layer between full detail sessions.
