Beyond cloth and water, these are the products we are currently recommending.
First is a totally new product by Turtle Wax called Hybrid Solutions Pro Flex. This is great without using anything else and by far makes your board the fastest. It is what we pre-wax with before shipping any BrownCastle board and what I most commonly use before playing because it is so fast and easy to apply.
Alternatively, you can use a mixture of these two products easily found at a store. Start by using Turtle Wax Super Hard Shell Finish Paste Wax. This takes only about ten minutes and does a good job. If you notice some hazy areas after polishing, continue gently buffing the paste wax in that area until it clears up. After that, we recommend using Mothers California Gold Instant Detailer Unmatched Speed & Gloss.
In both cases just follow the instructions detailed on the product.
