Herb from Snohomish, Wa writes
Mec Amine D 3-Way Broadleaf Herbicide should not leave a stain on pavement or pavers since it is a pale colored liquid. However, since this product has oils in it, we still recommend exercising caution when using this or other herbicides near porous surfaces such as stone or concrete. This product was discontinued by the manufacturer, so please let us know if you do not already have this and need a recommendation for a different product.
