Grey Deck Cleaner

Grey Deck Cleaner | High-Strength Timber Restorer

The professional-grade solution for reversing UV weathering and opening timber grain for a perfect finish.

Grey Deck Cleaner is a premium, Australian Made concentrated oxalic acid restorer. Unlike pre-mixed liquid cleaners that can lose potency sitting on a shelf, our crystal concentrate ensures you are applying a fresh, maximum-strength solution every time. This is a professional-grade, oxalic acid-based wood cleaner and brightener, specifically formulated to remove UV weathering. This essential preparation step ensures that finishes like Aussie Clear and Walnut Timber Finish give you a stunning result, every time.

Why Choose a Crystal Concentrate?

  • Optimum Freshness: By mixing the crystals yourself, you initiate a fresh chemical reaction that is far more effective at deep-cleaning wood fibres than aged liquid alternatives.
  • Maximum Potency: 1kg of crystals makes 10L of high-strength solution, providing a much higher concentration of active oxalic acid for stubborn UV weathering.
  • Cost Effective: One 1kg tub treats approximately 50m² of decking, making it the most efficient way to prepare large areas for Aussie Clear or Walnut Timber Finish.

Essential for Every Maintenance Cycle

  • Reverses UV Weathering: Strips the grey surface layer to reveal the sound, natural timber underneath.
  • Opens the Grain: Vital for new or weathered hardwoods (like Spotted Gum and Merbau) to ensure maximum oil penetration.
  • Removes Tannin Stains: Neutralises the “bleeding” of natural tannins that can discolour new timber and surrounding concrete.

Frequently Asked Questions

  • Why is a fresh mix better than liquid deck cleaners?
    Liquid cleaners can degrade over time. By mixing our crystals into hot water just before use, you ensure the oxalic acid is at its peak chemical strength, leading to a much faster and deeper clean.
  • Is it safe for my garden?
    When used as directed and diluted correctly during the rinsing process, Grey Deck Cleaner will not harm most established garden plants. We always recommend pre-wetting nearby foliage as a precaution.
  • Can it clean my concrete driveway?
    Yes! Because it is a high-strength oxalic acid, it is excellent for removing rust spots, tannin drips, and light oil stains from concrete and masonry surrounds.
