2019 Malibu Boats, LLC Owner’s Manual • Page 172Maintenance Tips: The real key to canvas longevity is like allthings in life: maintenance. Keep the canvas clean of dust, dirt andenvironmental residue on a regular basis.• Top fabrics should be cleaned of any dirt buildup at regularintervals.• We recommend applying a mild, lukewarm soap solution, suchas a liquid dishwashing soap, with a soft brush or sponge. Watertemperature is not to exceed 100o F. DO NOT allow the soap todry. The fabric must then be carefully rinsed with clear water inorder to remove any remaining soap residue. Allow canvas to drythoroughly. DO NOT USE DETERGENTS!• The use of abrasive detergents and/or substrates containingsolvents or gasoline will damage the fabric. If using high-pressureor steam-cleaning devices, use caution as improper use coulddamage the vinyl coating and/or fabric.• Using harsh chemicals could void the fabric warranty on your topif not recommended by the manufacturer.• DO NOT PUT MARINE CANVAS IN YOUR HOUSEHOLDDRYER. DO NOT DRY CLEAN BOAT CANVAS.UpholsteryEven if you do not have or use canvas covers, read the previousmaterial about canvas care as there is information that is applicableto upholstery use as well.NOTE: Topical cleaners must be wiped off with clean water anddried with a clean cloth after application. If not rinsed after directcontact, the cleaner residue on the surface can cause a slight colorchange.The performance resultsshown in this informationare not guaranteed for all upholstery products. Theevaluations are indicators after laboratory tests and maynot be indicative of field performance.Mold and Mildew: As noted in the Canvas information above,mold and mildew problems in the marine upholstery industry havebeen well-documented. The objective of this overview is to reviewthe causes and cures of the unsightly and odoriferous problems, andto suggest actions to reduce their impact on the quality of goods asperceived by the consumers.The Cause–Micro-organisms: The two principal causes ofoffensive odors and unsightly stains and growths are bacteria andfungi, commonly called micro-organisms. Bacteria are simple,single-celled organisms. Fungi, referred to as mold and mildew, aresignificantly more complex.A subset of fungal organisms is a type that produces coloredby-products as part of its digestive process. These by-products arerecognized as stains and are typically pink, yellow, purple or black.All micro-organisms require a source of energy, carbon for cellstructure, nitrogen for amino acid synthesis, essential minerals and water.Organisms causing problems in the marine, industrial, healthcare, hospitality and home environments are frequently very self-sufficient in synthesizing required bio-chemicals from the most basicmolecules. Micro-organisms are ubiquitous. They are everywhere,and thus, microbial contamination is the rule. The total absence ofmicrobes–sterility–is the exception.Current Reality: To have a mildew problem, four elements arerequired. In order for mildew to proliferate, spores, food, warmth andmoisture are necessary. Elimination of one of these elements wouldbreak the cycle, and the mildew problem would be eliminated.The most likely element to control is moisture. Keep surfaces dryand the ambient air dry, and you can break the link. In actuality, thisis very difficult. Marine upholstery may be dry when one sits on it, butit is constantly exposed to rain, splashes and wet bathing suits.Dirt carried by the wind or sudden shower will carry the spores orseeds to begin the process, inoculating the surface. Surface debriscan easily be washed off, but what happens to the contamination thatgets into a seam or stitch holes?A closer examination reveals that a marine seat is a very complexconstruction. The vinyl that you look at or sit on is a minute part of thetotal construction. The vinyl is usually attached to a fabric to give itdimensional stability and physical strength. Urethane foam of variousthicknesses provides a cushion, and the whole seat is usually built ona piece of plastic.If contaminated dirt carried by rain water gets inside the cushion,the biological growth cycle can begin. It is quite common for soilorganisms growing in the foam cushion to produce colored by-products, the most notable of which is a pink compound.This dye is soluble in plasticizer (an ingredient in flexible PVC)and will diffuse and migrate to the vinyl surface. Even though thevinyl compound is adequately protected against mildew growth,pink staining can occur if contact is made with components of aseat which support mildew growth. This stain cannot be removed bywashing. In any case, the owner’s perception of the boat’s quality hasbeen seriously affected.The Solutions: As in most complex problems, there are a varietyof actions once can take to prevent microbial problems.
