2017 OWNERS MANUAL / 354
In some instances, consumers have reported the appearance of 
a pink stain on vinyl that is resistant to various cleaning methods. 
Although there can be other causes for pink staining in vinyls, most 
pink stains are caused by dyes produced by micro-organisms. 
These dyes are metabolic products of the micro-organisms, 
otherwise known as a form of fungi.
It is virtually impossible for consumers to avoid these micro-organ-
isms as they exist in the atmosphere, which are more prevalent in 
high-humidity areas. Rain cleanses the air, with the result being that 
the micro-organisms are deposited on items such as marine vinyl.
While the vinyl is treated to resist the growth of micro-organisms 
(meaning the vinyl is not a food source), the stain results from fail-
ure to properly clean and maintain the vinyl. This means that after 
use, the upholstery must be cleaned with a soft brush and warm 
soapy water, followed by a thorough rinse with clean water.
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 finishing process, the material has been treated with 
a fluorocarbon finish, which enhances water repellency.
This finish is designed to last for several years, but it must be 
replenished after a thorough cleaning. Based on test results, the 
manufacturer recommends 303 High Tech Fabric Guard™ as the 
preferred retreatment 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 eective in restoring 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 five (5) 
years of use. 
ENCLOSED HEAD
An enclosed head is found on the X26 model. This convenience 
should be emptied on-shore within an acceptable holding tank, sep-
tic system or sewer. It should never be emptied within the boating 
body of water or on-shore, except in an approved receptacle.
The head should be cleaned after each outing. After thoroughly 
cleaning with a mild detergent, add a neutralizing chemical made 
especially for portable heads, such as that found in RV centers. The 
neutralizing chemical will help deal with potential odors that might 
otherwise be foul.  (See also Head under the Boat Operations sec-
tion of this Owner’s Manual.)
UPHOLSTERY
While the vinyl is made to withstand the elements, it is important to 
care for vinyl by keeping it clean at all times. Many substances may 
stain the vinyl if left untreated over a period of time. Remember to 
remove any contaminant and clean vinyl immediately.
Regular washing with mild detergent (see attached information) 
and warm water or vinyl cleaners is sucient to keep the cushion 
and vinyl coverings in good condition. 
Do not soak the cushion, and dry thoroughly after washing to 
prevent mildew accumulations when the boat is covered. Spray 
the cushions with a mildew repellent and prop them up in the boat 
when it is covered to take advantage of air circulation. MasterCraft 
vinyl is made to withstand the eects of sun, heat, acid rain and 
soiling, under normal conditions,  but this does not preclude the 
cleaning requirements. Please consult the following cleaning 
recommendations before cleaning your upholstery.
