The biggest challenge to homes with vinyl siding is keeping it clean!
Every 12 to 18 months your vinyl sided homes should be cleaned. 
This simple maintenance eliminates not only the dirt build up, but also any mildew and algae that may have formed (especially algae growth). 
If allowed to remain on the vinyl too long it becomes baked on and in our opinion, quite nearly impossible to remove. 

Your Vinyl Siding Cleaning Strategy:

• Prepare 1 Vinyl QSE premeasured EZ-Pouch  with 5 gallons of warm water.
• Apply to the surface area to be cleaned using home garden sprayer.
  (don't apply to the entire house but just a workable area maybe 10 feet wide).
• Start to apply Vinyl QSE from the Top and work to the bottom of the area.
• 10 minutes of soak time will thoroughly destroy the mold, mildew, algae,etc.
• Optionally, washing with soft bristle brush on densely infested or neglected spots.
• Rinse with garden hose (or pressure washer if available) to remove residue.
• Beam with pride at at your newly cleaned home!

Environment:
Vinyl Siding Cleaner is completely biodegradable. When washed into the earth, the product will break down rapidly. If this product is inadvertently sprayed on bushes or trees, it should be rinsed off. Although damage is NOT likely, rinsing with water will prevent the possibility of damage to the plants.
