How to Clean Concrete Outdoor Furniture

Concrete outdoor furniture is known for its bold presence and natural elegance. At Design Warehouse, our pieces are crafted from lightweight glass fibre reinforced concrete (GFRC), sealed for added protection and built to perform in outdoor settings. With the right care, your concrete furniture will age gracefully and retain its distinctive appeal for many years.

Our concrete furniture arrives pre-sealed, but ongoing care will help preserve its surface and prevent stains. For regular upkeep, follow these simple steps:

  • Wipe down regularly with a soft cloth and mild soap mixed with water.
  • Rinse with a garden hose—avoid high-pressure washers, which can damage the surface.
  • Clean spills promptly to avoid staining. For tougher marks, you can use a diluted bleach solution (1 part bleach to 2 parts water), but always test in a small area first and rinse thoroughly.

What to Avoid

  • Do not use harsh acid-based cleaners—these are too abrasive for furniture and can compromise the surface sealant.
  • Do not drag concrete tables or benches—always lift with care using multiple people to avoid cracks or chipping.
  • Avoid leaving standing water on the surface for extended periods, as concrete is porous and can absorb moisture over time.

The Nature of Concrete

Concrete is a natural, porous material that will gradually develop a lived-in patina. Small hairline cracks and surface variations are part of its organic charm and do not affect structural integrity. This weathered aesthetic is appreciated by those who value timeless materials and sculptural quality.

If desired, you may reapply a concrete-safe sealant over time. For guidance, contact us or consult your local home improvement store and always choose a product suitable for use on pre-sealed GFRC furniture.

With mindful care and regular cleaning, your concrete furniture will remain a sculptural, functional part of your outdoor setting for years to come.
