Mixing Instructions Dissolve in warm water to help it fully dissolve. Dilution for wood cleaning: Light cleaning: 2–3 oz per gallon of water. 175-225 sq ft per gallon Medium duty cleaning: 4-6 oz per gallon of water. 125-175 sq ft per gallon Heavy-duty cleaning: 7–8 oz per gallon of water. 100-125 sq ft per gallon Mix in a plastic bucket or sprayer. Application Pre-wet the wood Lightly spray the wood with clean water to prevent the cleaner from soaking in too fast. Apply the solution Let it sit for 5–10 minutes for light soil, or up to 15 minutes for heavy buildup. Keep the surface wet with the solution during this time — don’t let it dry out. Rinsing Rinse thoroughly with a low to medium pressure stream (no more than ~800 PSI for softwoods) to avoid damaging the grain. Make sure all residue is removed, as leftover alkalinity can cause discolouration or interfere with sealers. Neutralizing (Optional but Recommended) After cleaning, especially before staining or sealing, use a mild acidic neutralizer like Oxalic Acid to bring the pH back to neutral. Tips for Best Results Avoid cleaning in direct hot sun — solution may dry too quickly and cause streaks Work in manageable sections to keep dwell time consistent. Keep away from aluminum and glass — may cause etching. Store any unused Sodium Metasilicate in a sealed, moisture-proof container Dilution for Concrete cleaning: Light Mix use 5oz per gallon of water (3/4 jar/ 5 Gallon) Strong Mix use 8oz per gallon of water (1.25 jars/ 5 Gallon) Extreme Mix use 12oz per gallon of water ( 2 jars/ 5 Gallon) Mix in a plastic bucket or sprayer.
