Important: Fire Safety Information
While CertainTeed Cedar Impressions  
siding resists most common household 
stains like oil and grease, it will become 
dirty like any other product that is 
exposed to atmospheric conditions.  
Chalk may also accumulate on the  
surface. This is a normal condition for  
all pigmented materials which are  
constantly exposed to sunlight and the  
elements. Soil, grime and chalk can be 
removed with your garden hose and a 
bucket of soapy water. If especially  
stubborn stains cannot be removed with 
normal household detergents, request a 
cleaner from your contractor. Always test 
any cleaner on an inconspicuous area 
before full use. Siding products should  
not be cleaned with a power washer.
Mold and mildew may be a problem in 
some areas. They may appear as black, 
gray or green spots on surface dirt and are 
usually first detected in areas not subject 
to rainfall, such as under eaves and porch 
enclosures. Mold and mildew can be 
removed with the following solution:
Mix together: 1⁄3 cup of detergent  
(Tide, for example), 2⁄3 cup of Trisodium 
Phosphate (SoilMax, for example), one 
 quart of 5% Sodium Hypochlorite 
(Clorox, for example) and three quarts of 
water. (Caution: Greater concentrations 
may cause damage to vinyl siding.)
If the above solution does not readily 
remove the mold or mildew, request a 
mold and mildew-type cleaner from  
your contractor.
NOTE: The chemical agents referenced  
above may be hazardous to the user or  
to the environment. Please follow all  
precautions and warnings on the product 
label, particularly those which may be  
necessary to prevent personal injury.  
Always dispose of these chemical agents  
in a manner prescribed by the manufacturer. 
If you are unsure how to use or how to  
properly dispose of these chemical agents, 
please contact the manufacturer of these 
products for instructions.
Cedar Impressions products require  
little maintenance for many years. 
Nevertheless, common sense dictates 
that builders and suppliers of these  
products store, handle and install  
these materials in a manner that avoids 
damage to the product and/or the  
structure. Owners and installers should 
take a few simple steps to protect siding 
products from fire. 
Rigid siding products are made from 
organic materials and will melt or burn 
when exposed to a significant source  
of flame or heat. Building owners,  
occupants and maintenance personnel 
should always take precautions to keep 
sources of fire, such as barbecues, and 
combustible materials such as dry  
leaves, mulch and trash, away from  
siding products.
