Unless you have a nude TI frame Pledge is worthless! It will not hold up to the outdoor activities, it's made for furnature, but on TI it will shine it up but not protect it...TI doesn't need protection. Also Pedros wax is expensive especially since you can use standard non-abrasive car wax and it will do the same if not better job for less money. For painted surfaces get a auto wax like Mequires Gold Class or Mothers California Gold, both of these waxes have no abrasives so is safe on all clear coat finishes and are durable-especially the Mequires.
I clean my bike using Finish Line Bike Wash because I have a steel bike and the wash contains a rust inhibitor so I don't have too worry about it rusting just because I washed it, and it's biodegradeable.
