How to Remove Concrete From Vinyl Siding

Modern technology provides many home and garden materials that are durable and easy to clean. For the outside of a home, vinyl siding is a preferred low-maintenance product. Still, accidents can occur, leaving your vinyl siding in need of some attention. Concrete splatter, for example, can dry on vinyl siding, requiring a special cleaning regimen to completely remove the evidence of this stain. Wet concrete tends to adhere to many surfaces, so it may be necessary to dissolve the concrete with chemicals to completely remove it.

    • 1

      Spray water on the area of vinyl siding where the concrete splatter is located, using a garden hose.

    • 2

      Scrub the concrete spots with a stiff-bristle brush. Use firm strokes, but avoid scratching the vinyl siding.

    • 3

      Apply a vinyl siding cleaner with phosphoric acid to the area with the concrete splatter. Scrub with a sponge, removing as much of the concrete as possible. Rinse thoroughly with the garden hose.

    • 4

      Put on the protective goggles and heavy protective gloves. Muriatic acid is extremely caustic and can cause permanent injuries.

    • 5

      Fill the plastic bucket with warm water. Carefully add 1 part muriatic acid to 10 to 20 parts of water.

    • 6

      Dip the paintbrush in the muriatic acid. Test the solution on an unobtrusive area of the vinyl siding. If damage occurs to the siding after you apply the muriatic acid, discontinue the cleaning process.

    • 7

      Brush the muriatic acid solution on the concrete splatters. Allow the solution to sit for up to several minutes, or just until the concrete is visibly dissolved. Rinse.

    • 8

      Repeat Step 7 on all areas where concrete is present on the vinyl siding.
