Intense dirt/Prominent stains
: Apply warm or hot detergent or an ammonia-based
remover (domestic removers) and water solution. If this is not enough to remove burnt
food or charred deposits, use more aggressive products, such as caustic soda-based
removers used in domestic cleaning.
11.2 Maintenance and preservation of polycarbonate
(doors)
Routine cleaning:
Choose a dry day (preferably with low humidity) because it will be
easier to remove soot that may be on the door.
If possible, remove the polycarbonate item for optimum cleaning.
Wet the polycarbonate doors with water. Add water until you see that excess dirt has
come loose. The water must be plenty because cleaning the soot with a cloth without it
being properly wet could cause scratches on the door or leave the door blurred and
without any shine.
Get a 100% cotton cloth and a neutral detergent with good precedence. Do not use a
common broom because it will scratch the polycarbonate.
Add the detergent to water inside a bucket until a lot of foam has formed and lightly
spread this solution with cloth in only one direction
–
the direction of the water flow. Do
not make circular movements with the cloth. Rinse well and repeat the process until the
result is satisfactory.
Do not let the solution to dry under the sun
–
it can stain the polycarbonate.
Paint Splatters on the Polycarbonate:
It is common, when painting walls, to splatter
some of the latex paint over the polycarbonate sheet. Do not use solvents as thinner,
gasoline, benzene, or acetone. Isopropyl alcohol or kerosene can solve the problem. Try
to remove the paint before it dries and rinse the area with a water and neutral detergent
solution.
Frequency of Cleaning the Polycarbonate:
There is no determinate period for
cleaning. The amount of soot in the air, caused by unpaved streets, factories, and
buildings near the installation site can be reason for a more frequent cleaning routine.
Clean the polycarbonate once a month and then analyze the situation. You can adapt this
period according to your convenience. However, clean without scratching it.
NOTE -
Even when dealing with resistant dirt, start cleaning with the softest
method. Be patient and repeat the operation for a number of times before employing
methods that are more aggressive
