What’s the Difference Between Wood Cleaning and Wood Restoration?

When you talk with a customer about exterior wood care, start by asking whether they want you to simply clean the surface or fully clean and restore wood deck and fences. This distinction affects your process, your pricing, and the final results.
Wood cleaning means you are washing the surface to remove dirt, mold, mildew, and other organic growth. To clean at a basic level, this can be done with a pressure washer or a soft washing system, such as the efficient ProTool Mix Station Mobile. However, customers need to understand that simple cleaning may remove some prior coatings, slightly depreciate the wood, and will not make it look like brand-new lumber or freshly stained boards.
Wood restoration goes further and is the process professionals use when they truly want to clean and restore wood deck and fences back as close as possible to their original appearance. This can include stripping old stains or sealers, correcting discoloration, and preparing the surface for a new, long-lasting coating. Because restoration involves more chemistry, time, and skill, the price difference between basic cleaning and full restoration should be significant.
Why Bleach Is Not the Best Option to Clean and Restore Wood Deck and Fences
Many in the soft washing industry are asked to clean and restore wood deck and fences, but a lot of them rely too heavily on sodium hypochlorite (bleach). While bleach is common in soft washing, it is rarely the best primary cleaner for wood.
Chlorine bleach is designed to remove color and kill organic growth like mold and mildew, and it works well on non-porous surfaces such as vinyl siding and roofs. Wood is porous, so bleach does not clean evenly and can damage the substrate if the mix is too strong or left too long. It can bleach tannins, dry out wood, damage lignin (the “glue” that holds wood fibers together), and cause fuzzing, degradation, poor stain adhesion, and premature coating failure. Bleach may also void warranties on composite decks and some stain systems.
Bleach still has a limited role when you clean and restore wood deck and fences, but it should only be used at household-strength levels (around 5–7% SH) strictly to kill organic growth on the surface, followed by thorough rinsing—not as the primary restoration chemistry.

Why Use a Wood Brightener After You Clean and Restore Wood Deck and Fences?
Wood brighteners are an essential finishing step when you clean and restore wood deck and fences, and they serve four important purposes:
Neutralize high-alkaline cleaners so the wood’s pH is brought back into balance.
Neutralize and remove iron and metal stains that can show through coatings.
Open the wood’s pores so stains and sealers bond more effectively.
Lighten and brighten the surface, making the deck or fence more visually appealing.
After cleaning, applying a brightener such as ProTool Wood Brightener and Neutralizer (oxalic acid plus a proprietary blend) helps “reset” the wood. It is often called “wood bleach” because of how it reacts with tannins, pulling out rich natural color and removing metal stains like nail bleeds that would stand out once you restain.
Four Core Steps to Clean and Restore Wood Deck and Fences
Apply products to wet wood surfaces.
Pre-wetting is standard when you clean and restore wood deck and fences. Wetting the wood first helps the cleaner work closer to the surface, improves mold and mildew removal, and prevents chemicals from soaking too deeply into the fibers.Let the cleaner, stripper, or brightener do the work.
Apply the appropriate product—cleaner, stripper, or brightener—and allow proper dwell time so it can lift contaminants, coatings, and discoloration. This approach allows you to restore wood with the least amount of pressure, instead of “blasting” with water and relying only on PSI, which is not true restoration.Rinse wood surfaces thoroughly.
After using any chemical, rinse, rinse, and rinse again. Thorough rinsing removes residues that can dry out the wood, leave salt deposits, or cause coating failure. This is critical if your goal is to truly clean and restore wood deck and fences for long-term results.Apply a protective coating or stain.
Once you clean and restore wood deck and fences, always follow up with a quality stain or sealer, whether done by the contractor or homeowner. Coatings lock in your restoration work, extend the life of the wood, and enhance the overall appearance.
FAQs
What is the difference between wood cleaning and wood restoration?
Wood cleaning is a surface-level process that removes dirt, organic growth, and light buildup from the wood using a pressure washer or soft washing system. Wood restoration goes further by stripping previous stains or sealers and working to return the wood as close as possible to its original color and condition.
Why isn’t bleach (sodium hypochlorite) the best option for cleaning wood?
Bleach is designed to kill organic growth and remove color, and it works well on non-porous surfaces, but wood is porous. Too strong a mix, or leaving it on too long, can bleach tannins, dry out the wood, damage lignin (the “glue” in wood), cause fuzzing, and lead to poor stain adhesion and coating failure.
What is ProTool Oxy Wood Cleaner best for?
ProTool Oxy Wood Cleaner is ideal for cleaning and prepping new or grayed wood, safely removing mold and mildew to help restore wood to its more natural color. It is environmentally friendly, contains no chlorine or hypochlorite bleach, and is safe on exterior wood and composite decking.

Use ProTool Deck and Fence Cleaner on more challenging wood surfaces where you need stronger cleaning and help removing weathered or transparent coatings. It provides superior cleaning in a one-step process and is safe for decks, siding, lattice, fencing, and composite decking.

Remove iron and metal stains in the wood.
Open the wood’s pores so coatings bond better.
Lighten and brighten the surface for a more attractive finish.
