What is efflorescence and can it be removed?
Efflorescnce is a white haze that may appear on the surface of concrete pavers after a few weeks or months. Efflorescence is completely natural and will disappear with time. Your paving stone is not damaged or defective. Efflorescence is produced by cement which is a necessary ingredient in all concrete products. It will eventually go away naturally, but there are commercial cleaners available that are specifically formulated for concrete pavers. Most cleaners contain acid and detergents, so be sure to follow all label directions and enviromental regulations when using these cleaners.
