How To Clean Adhesives from Concrete
Overspray from adhesive projects, misplaced stickers, duct tape and other household spills or misplacements can result in a sticky residue on the concrete surfaces of your home. Although these particular stains are dirt magnets, they can be removed effectively with very simple techniques. Concrete base materials and surface treatments can vary, so test all cleaning solutions and application techniques in an inconspicuous location before using them in a wider area.
For small marks that are confined to small areas, use WD-40 that is conveniently available in a pen applicator. Apply according to the manufacturer's directions. Follow by cleaning the area with a lightly sudsy solution of water and mild pH neutral dish liquid, applied with a clean sponge to remove any WD-40 residue.
For larger areas, use a non-flammable chemical stripper designed to remove adhesive. These should be readily available at a variety of hardware stores, and should be applied according to the manufacturer's directions. Particularly in areas such as the garage, where there might be different volatile chemicals, it is best to use these non-flammable options to help prevent undesirable results. Follow application of the chemical stripper and adhesive removal by cleaning the area with a lightly sudsy solution of water and mild pH neutral dish liquid, applied with a clean sponge to remove any stripper residue.
Caution: Never mix cleaning agents or chemicals, the result can be dangerous or deadly. Before cleaning, always test the agent on an inconspicuous location to determine its suitability and to make certain it does not damage the material. Wear appropriate clothing such as gloves and protective eyewear, and work in a well-ventilated area. Accidental inhalation or ingestion of cleaning agents can be hazardous and even fatal, particularly to pets and children.
