Recommended Coil Cleaner
CAUTION
Harsh Chemical and Acid Cleaners
Harsh chemicals, household bleach or acid cleaners should
not be used to clean outdoor or indoor Option E Coated
Coils. These cleaners can be very difficult to rinse out of the
coil and can accelerate corrosion and attack the Option E
coating. If there is dirt below the surface of the coil, use the
recommended coil cleaners as described above.
High Velocity Water or Compressed Air
High velocity water from a pressure washer or compressed air
should only be used at a very low pressure to prevent fin and/
or coil damages. The force of the water or air jet may bend the
fin edges and increase airside pressure drop. Reduced unit
performance or nuisance unit shutdowns may occur.
The following cleaning agent, assuming it is used in
accordance with the manufacturer’s directions on the container
for proper mixing and cleaning, has been approved for use
on Option E Coated Coils to remove mold, mildew, dust, soot,
greasy residue, lint and other particulate:

Chlor*Rid DTS
CHLOR*RID DTS™ should be used to remove soluble salts
from the Option E Coated Coil, but the directions must be
followed closely. This product is not intended for use as a
degreaser. Any grease or oil film should first be removed with
the approved cleaning agent.
1. Remove Barrier - Soluble salts adhere themselves
to the substrate. For the effective use of this product,
the product must be able to come in contact with the
salts. These salts may be beneath any soils, grease or
dirt; therefore, these barriers must be removed prior to
application of this product. As in all surface preparation,
the best work yields the best results.
2. Apply CHLOR*RID DTS - Apply CHLOR*RID DTS
directly onto the substrate. Sufficient product must be
applied uniformly across the substrate to thoroughly
wet out surface, with no areas missed. This may
be accomplished by use of a pump-up sprayer or
conventional spray gun. The method does not matter, as
long as the entire area to be cleaned is wetted. After the
substrate has been thoroughly wetted, the salts will be
soluble and is now only necessary to rinse them off.
3. Rinse - It is highly recommended that a hose be used,
as a pressure washer will damage the fins. The water to
be used for the rinse is recommended to be of potable
quality, though a lesser quality of water may be used if a
small amount of CHLOR*RID DTS is added. Check with
CHLOR*RID International, Inc. for recommendations on
lesser quality rinse water.
