Cleaning
One of the best ways to keep the material looking fresh 
and new, and to delay the need for deep or vigorous 
cleaning, is to hose off fabrics with clear water on at least 
a monthly basis with clean water. This practice will help 
prevent dirt from becoming deeply imbedded in the fab-
ric, and it will eliminate the need for more frequent and 
more vigorous cleanings.
In most environments, a thorough cleaning will be need-
ed approximately every two (2) years. 
The fabric can be cleaned while still in the boat. When 
cleaning, it is important to observe the following:
•  Always use a natural soap—never detergent.
•  Water should be cold to lukewarm, but never more 
than 100 degrees.
•  Air dry only. Never apply heat to the fabric.
Begin by brushing off loose dirt, and then hose down the 
material. Prepare a cleaning mixture of water and a mild, 
natural soap that is free of detergents. Use a soft-bristle 
brush to clean, allowing the soap to soak in. Rinse thor-
oughly and allow the fabric to thoroughly air dry.
If stubborn stains persist, you can use a diluted chlorine 
bleach/soap  mixture  for spot  cleaning of  mildew,  roof 
run-off and other similar stains. Please keep in mind that 
chlorine bleach will not change the color of the fabric, 
but chlorine bleach will eventually break down the ber 
of any fabric. Therefore, this cleaning method should be 
used as infrequently as possible. 
The cleaning mixture should be mixed as follows:
•  Four ounces (one-half cup) of chlorine bleach.
•  Two ounces (one-fourth cup) of natural soap.
•  One gallon of water.
Clean with a soft-bristle brush and allow the mixture to 
soak no longer than twenty (20) minutes. Rinse thoroughly 
and allow to completely air dry. Repeat if necessary. 
If the top or boat cover is suitable in size for a washing 
machine, these steps should be followed:
Use only natural soaps—no detergent.
Wash and rinse in cold water.
Air dry. (Never put the fabric in a dryer.)
As part of the nishing process, the material has been 
treated with a uorocarbon nish,  which enhances wa-
ter repellency. This nish is designed to last for several 
years, but it must be replenished after a thorough clean-
ing.  Based  on  test  results,  the  manufacturer  recom-
mends 303 High Tech Fabric Guard™ as the preferred 
re-treatment product. 
After cleaning and air drying, apply 303 in a thin, even 
coat. When it has dried, apply a second thin, even coat. 
These two (2) light coatings are more effective in restor-
ing fabric water resistance than a single heavy coating. 
Keep in mind that 303 High Tech Fabric Guard™ will 
work only as well as it is applied. This means that the 
fabric must be free of dirt and detergents or the Fabric 
Guard will wash away with the dirt particles. 
Fabrics should be retreated after thorough cleaning or 
after ve (5) years of use. 
Enclosed Head
An  option  on  some  models  is  the  enclosed,  portable 
head.  This  convenience  should  be  emptied  on-shore 
within an acceptable holding tank, septic system or sew-
er. It should never be emptied within the boating body of 
water or on-shore, except in an approved receptacle! 
After  thoroughly  cleaning  with  a  mild  detergent,  add 
a  neutralizing  chemical  made  especially  for  portable 
heads, such as that found in RV centers. The chemical 
will help deal with potential odors that might otherwise be 
foul. Even with the use of this neutralizing chemical, the 
head should be cleaned after each outing.
Slick Boot
The optional Slick Boot should periodically be disman-
tled, cleaned and the wand thoroughly rinsed. The Slick 
Boot material can sometimes become gelled, particularly 
in colder weather.
