clay first before wax.

and may be your shampoo remove the wax already ...  try use turtle brand if you not afford meguiars

diluted shampoo is the most economical way. but need to rinse with water after claying.

if not can try
1. Meguiars Quik Detailer
2. Optimum ONR
3. Meguiar's Last Touch (pro range)

As bro slk mentioned about the clay lubricant, so wont elaborate further. However, if u never owned a claybar kit before, then can buy the Meguiars Claying Kit available in most Ace Hardware outlets. It already comes with 1 bottle of Meguiars Quik Detailer and 2 claybars (each bar can cut into 2 for more uses), so no need headache on what claybar and what lubricant to use.

Just to share a technique I use to maximize Quik Detailer with minimal wastage, when spraying it on body surface squeeze the trigger while moving left to right or up to down. Dont spray on one spot or stagnant position. This will give more coverage of lubricant to car surface. If done right, 1 bottle Quik Detailer can cover 2 typical sedan cars for claying.
