OxyShock HD | Ready-To-Use Wood Cleaner & Brightener | Heavy Duty Organics Cleaner

OxyShock HD is a ready-to-use, heavy-duty organics cleaner from StoneSealer Canada that cleans and brightens weathered wood in one step. Spray it on, let it work, rinse it off: grey, mossy, mildewed decks and fences come back to clean, warm natural wood with no mixing, no dilution and no separate brightener.

Clean and brighten wood in one step

Most wood restoration takes two products: a cleaner to lift the grime, then a brightener to bring the colour back. OxyShock HD does both in one application. It breaks down the algae, mould, mildew and organic staining that turn cedar and other woods grey and green, and it brightens the wood underneath. One product, one pass, one rinse, and the wood is ready to dry for sealing or staining.

Key benefits of OxyShock HD

• Cleans and brightens weathered wood in one step: no separate brightener needed
• Ready to use straight from the pail: no measuring, mixing or dilution ratios
• Heavy-duty formula for severe organic stains, stubborn algae, mould and mildew
• Works on vertical and horizontal surfaces: fences, siding, decks and stairs
• Fewer passes and less labour on heavy restoration jobs
• Also tackles organics on roofs, concrete, stone and other hard-wearing outdoor surfaces

Made for homeowners and professionals alike

For homeowners

No equipment beyond a garden pump sprayer and a hose. Because it comes ready to use, there are no ratios to get wrong: pour it into the sprayer, apply, and rinse. It's a simple way to bring back a weekend deck, a backyard fence or a set of cedar stairs before resealing.

For professionals

Run it through your soft-wash or pump-sprayer setup straight from the pail, with no batch mixing on site. The heavy-duty formula and one-step clean-and-brighten cut down passes and labour time on deck, fence and siding restoration, so crews can finish more square footage per day with consistent results from job to job.

How to use OxyShock HD on wood

1. Clear the surface of furniture and debris. Wet down nearby plants and surfaces you are not cleaning.
2. Test on a small, hidden area first to confirm the result on your wood.
3. Apply OxyShock HD straight from the pail with a pump sprayer or soft-wash system, working in manageable sections.
4. Let it dwell and keep the surface wet; do not let it dry on the wood. Agitate heavy buildup with a soft deck brush.
5. Rinse thoroughly with a garden hose or low-pressure wash, working with the grain.
6. Let the wood dry completely before sealing or staining.

Built for the Canadian climate

Wet coastal BC winters and humid summers elsewhere in Canada turn exposed cedar grey and green fast. OxyShock HD is built for the heavy organic growth that builds up season after season on shaded decks, north-facing fences and cedar siding.
