It usually take me around 1 hour - 2 hours. I use the 3 bucket method. One bucket full of suds and a bucket full of fresh water. Wash the wheels first dipping the lambs wool mitt into the fresh water bucket before dipping it into the suds bucket. This removes anything caught in your mitt that might scratch the car. After the wheels are done, tip those buckets out. Refill the fresh water and put suds in another clean bucket, not the one you used for the wheels. Also use another mitt and like the new bucket, never use this one on the wheels. After washing the car, I use a drying towel. I'll never let a chamois touch my paintwork. Chamois are only used for the dirty areas like the rims, inside the boot, enginebay and door seals. Once the car is washed and dry, I then go over it with a Quick Detailer and a microfibre cloth to top up the wax or sealant I have on the car. Plexus is used on the headlights, tailights and windows. Once again, this is applied with a microfibre cloth. The interior and leather gets done once a month.
