| Portico Composite Decking
is primarily wood-based, and will require occasional cleaning.
Most conventional deck cleaners work well on everyday dirt and
traffic areas. |
|
Periodic pressure washing
is an acceptable method of removing persistent stains. Extractive
bleeding can result in a surface stain. This is especially true
with flower pots, certain deck furniture and other items stored
directly on the deck surface. All wood based composite decking
products
can experience this type of staining. |
|
If extractive bleeding should
occur, many conventional deck cleaners are effective for cleaning
or the following cleaning procedure should be utilized: A solution
of 4 ounces oxalic acid crystals (also known as wood bleach),
generally found in the paint department of your retail store,
should be dissolved in a non-metal container with a gallon of
warm water. The solution should be brushed over the stained
area and left for approximately fifteen minutes followed by
a thorough rinsing with clear water. Within a 24 to 48 hour
period, the stain should dissipate. If remnants of it persist,
the procedure can be repeated, although normally any traces
of the stain should disappear with additional time. |
|
| As a substitute
to oxalic acid, a solution of 1 cup trisodium phosphate (TSP),
1 cup household bleach and 1 gallon warm water should also
be effective. If only a portion of the total deck is cleaned,
there will be a variance in surface appearance between the
cleaned and un-cleaned portions of the deck. This variance
will fade over time. Always test a small section before
applying any product to your Portico Composite Decking. |
