Do not "Spot Clean" as this may result in a patchy appearance
Clean the whole area at the same time. DEX PREP may not remove old deep seated fungal stains and timber marking dyes. For best results apply DEX PREP to cool surfaces out of direct sunlight. Do not allow to dry on the surface before removal. Failure to remove the cleaning solution residue may result in timber discolouration under clear finishes or early failure of the coating due to changed pH. DEX PREP is mildly acidic, avoid contact with painted metal surfaces and vegetation. Rinse thoroughly if contact occurs.
Application :
Remove surface dirt by sweeping or hosing.
Shake DEX PREP thoroughly and mix in a plastic container or bucket. General Cleaning: Mix one part DEX PREP to 5 parts water Severe Staining: Apply neat.
Wet the surface to be cleaned.
Apply mixture generously with a scouring or scrubbing brush and scrub timber thoroughly. Leave for 10-15 minutes.
Rinse off using a garden hose, or high pressure water cleaner for large area or badly discoloured timber.
