Some Times Efflorescence may appear after rain or heavy dew and frost. It is caused by the water evaporating out of the Concrete Sleepers and drawing salts and lime from the chemical composition of the Sleeper , paver to the surface. It is easily removed by washing the Concrete Sleepers Down with an acid solution.

CLEANING THE CONCRETE STAINS

Concrete Sleepers and Pavers can be cleaned with 20 to 1 water to hydrochloric acid solution. Wet down pavers first. Use a broom to apply the solution to the Sleepers,pavers. Apply the solution to the whole area so the concrete  stays consistent. Be sure to cover up so acid doesn't go on you. The stronger the solution, the coarser the Sleepers , pavers finish will become. Use lots of water to wash down cleaned area.
