What is the proper method for cleaning the synthetic rocks?
The synthetic rocks can be cleaned with water and a nylon brush. If calcium or alkaline buildup develops, a mild diluted acid solution may be used. To clean with an acid solution, wet down the rock with water then spray on the mild diluted acid solution. Let the solution remain on the surface for five minutes. Use rubber gloves and wear safety glasses before scrubbing the stains with a nylon brush.
