Your garage probably looks like a cleaning product graveyard. Deck cleaner. Concrete degreaser. Wood brightener. Fence wash. Each bottle promises to tackle one specific surface.
What if you could replace that entire collection with a single concentrated formula? That's the idea behind Seal-Once Multi-Surface Cleaner.
Can You Use the Same Cleaner for Wood and Concrete?
Yes, but most cleaners can't handle both effectively.
Here's the problem: wood and concrete have completely different cleaning needs. Wood is porous and organic, susceptible to tannin stains and mildew. Concrete is alkaline and mineral-based, prone to oil stains and efflorescence.
Traditional cleaners optimize for one or the other. A concrete degreaser strong enough to cut through oil will strip wood fibers. A gentle wood cleaner won't touch petroleum stains on garage floors.
Seal-Once Multi-Surface Cleaner solves this by penetrating below the surface. Unlike typical surface cleaners that only scrub away the top layer, Seal-Once's formula works with both materials because it breaks the bond between dirt and surface at the source.
Wood fibers trap dirt deep in the grain. Concrete pores absorb stains from within. Both materials need cleaning that doesn't leave chemical residue behind.
Where other multi-surface products force you to choose between wood-safe or concrete-effective, Seal-Once Multi-Surface Cleaner handles both.
What Removes Mold and Algae from Outdoor Surfaces?

Mold, mildew, and algae aren't just ugly. They break down wood fibers and create slippery, dangerous surfaces on concrete and stone.
Most outdoor cleaners fall into two categories: bleach-based products that kill mold but damage plants and materials, or "eco-friendly" formulas that barely touch established growth.
Effective removal requires breaking down the organic root structures that anchor into porous surfaces and eliminating the food sources (tannins, sugars, minerals) that feed new colonies.
Seal-Once Multi-Surface Cleaner handles both tasks without harsh chemicals. Unlike bleach-based products that can harm your landscaping or weak eco-formulas that leave mold behind, Seal-Once's biodegradable formula penetrates deep into wood and concrete, eliminating mold, mildew, and algae while removing the organic matter they feed on. Surfaces stay cleaner longer because you've addressed the root cause, not just the visible symptoms.
Why Seal Once’s Concentrated Formula Makes Sense
Seal-Once Multi-Surface Cleaner comes as a concentrate in two sizes: 1 pound (16oz) or 2 pound (32oz). This gives you real advantages beyond mixing your own dilution strength.
You're not paying to ship water across the country. The concentrate format means less plastic waste, lower fuel costs in transportation, and better value per use.
Storage becomes manageable. One bottle of Seal-Once Concentrate takes up minimal space. Mix what you need when you need it instead of storing multiple half-empty spray bottles of different products.
You control the strength based on the job. Light cleaning of patio furniture? Mix a weaker solution of Seal-Once. Cleaning years of neglect from a deck? Make it stronger.
Cost per use beats ready-to-use cleaners significantly. Break down the actual cost per gallon of working solution and you're paying a fraction of what pre-mixed products cost while getting professional-grade results.
Preparing Surfaces for Sealers and Stains
The cleaner you use before applying wood sealer or concrete sealer directly affects sealer performance.
Mill glaze from fresh-cut lumber prevents proper sealer absorption. Most cleaners don't touch it. Seal-Once Multi-Surface Cleaner's penetrating formula breaks down mill glaze, opening wood pores for maximum sealer penetration. It also eliminates tannin and rust stains that most cleaners leave behind.
Tannin stains create barriers that prevent sealers from adhering properly. Seal-Once removes them completely, preventing peeling and uneven coverage.
Old degraded sealer residue interferes with new applications. Seal-Once Multi-Surface Cleaner lifts it completely, preparing surfaces for a fresh start.
Concrete needs neutral pH for sealers to cure correctly. Proper cleaning with Seal-Once brings concrete to the right pH for optimal sealer adhesion; something many harsh chemical cleaners fail to achieve.
How to Mix and Apply Seal-Once for Best Results
Standard dilution: Mix 1/2 cup Seal-Once Multi-Surface Concentrate per gallon of water for routine cleaning.
Double the concentration (1 cup per gallon) for heavy mold, severe staining, or neglected surfaces.
After mixing Seal-Once, let the solution rest for 15 minutes before using. Stir occasionally during this time. This activation period allows cleaning components to reach full effectiveness.
Application methods:
- Garden sprayer for large decks, fences, driveways
- Mop or brush for smaller areas requiring more control
- Apply Seal-Once first, wait 10-15 minutes, then pressure wash
Never let the cleaner dry on the surface. Work in shade when possible. Rinse thoroughly until water runs clear. Allow complete drying before applying sealers.
What Multi-Surface Cleaner Handles
Wood applications: decks, fences, log homes, outdoor furniture, pressure-treated lumber, Brazilian hardwoods, shingles and shake roofs.
Masonry and concrete: driveways, garage floors, patios, walkways, pavers, brick, stucco, unglazed tile.
Marine environments: docks, piers, boat decks, waterfront structures.
Seal-Once handles all these because it works with the material, not against it. Instead of harsh chemicals that etch concrete or strip wood (like many competitor products), Seal-Once's penetrating action lifts dirt while preserving surface integrity.
Low VOC and Biodegradable Benefits
VOCs (Volatile Organic Compounds) affect air quality and contribute to smog. Seal-Once Multi-Surface Cleaner's low VOC formula means you're not breathing chemical fumes while working.
Biodegradable means Seal-Once's formula breaks down naturally after rinsing. When you wash your deck or driveway, runoff doesn't persist in groundwater. Soil microorganisms break it into harmless components.
No harsh odor during or after application makes the job more pleasant and safer for everyone nearby.
Professional Tips for Better Results
Work in sections, not all at once. Complete one zone (apply, scrub, rinse) before moving to the next. This prevents the cleaner from drying before you can scrub it.
Pre-wet heavily stained areas with plain water before applying Seal-Once Multi-Surface Cleaner. This prevents stains from absorbing the cleaner.
For severe buildup, use a two-step approach. Clean, rinse, let dry completely, then repeat. This staged method works better than one aggressive pass.
Rinse more than you think necessary. Residual cleaners can interfere with sealer adhesion. Keep rinsing until water runs completely clear.
Apply wood brightener within 48 hours of cleaning. Let concrete dry 24-48 hours before sealing.
Bottom Line
You don't need different bottles for different jobs anymore. One properly formulated concentrate (Seal-Once Multi-Surface Cleaner) handles wood, concrete, masonry, and marine surfaces with equal effectiveness.
Seal-Once delivers because it penetrates below the surface instead of just scrubbing the top, removes actual stains (not just surface dirt), eliminates mold and algae at the root, prepares surfaces properly for sealers, and outperforms competitor products that only specialize in one surface type.
The concentrated formula means less plastic waste, lower shipping costs, flexible dilution strength, and significant cost savings.
