Default 1jz overboost

My car recently is having a bit of a problem with overboosting even with the boost controller turned all the way down. Apparently the wastegates can get a build up of carbon over time and cause this. What is the easyest way to clean them? Start pulling stuff off to get to them or is there an additive you can put in the fuel that will aid this. Or could it be overboosting for another reason?
