Here are some general guidelines...
Graphene Detail Spray, every 2 weeks
Graphene CS3, every 1-2 months
Graphene Boost, every 4-6 months
You can alternate those listed above or use them by themselves on that general cycle.
For washing, you can use regular Car Shampoo or Mega Foam routinely, but swap for Graphene Shampoo every 3-4 washes.
