Go to the Specialized Job marker near the Del Perro Pier at the lifeguard station.
Go to the orange job selector circle and choose Beach Clean Up.
Go to the blue circle and Go on Duty.
You should see 5 question marks on your map.
This is where you spawn your beach clean up vehicle. Spawn the appropriate vehicle for your Garbage level.
You should see three sand excavation zones along the beach. Once you enter these very large blue circles, you will start to gain Garbage Collectorexperience, sand, and trash as you drive your beach clean up vehicle in the circle.
Occasionally you will see red circles inside the big blue area. If you drive through them, you will receive a bonus!
It is also a good method of leveling up your garbage skill if you’re not a fan of the Garbage routes, a bonus of doing it this way is that you will accumulate Sand which can be sold to other players or used to make concrete or other goods.
