The first thing to do is grab the cleaner from the kit and shake it well. Then, mix the cleaner with 2 parts lukewarm water and apply the mixture to the wood with the sponge. Note that the kit includes a regular sponge and a sanding sponge, and for this step you should use the regular sponge.
Apply it in an even layer followed by a rub in the direction of the grain and apply light pressure until it lathers.
Leave for 5 minutes and wash down with lukewarm water. If the wood has risen or feels rough after it is dry, lightly rub down with the sanding sponge. And remember, always along the grain.
