The pull out platform the settee cushions sit on can be lifted off. Under that is an access plate that screws off. I usually in the spring use a clean microfiber cloth and wipe down the tank with clean water and a little bit of bleach.
There are various chemicals you can add ( Sudbury Aqua Fresh and such ) that work well. I routinely add a small amount of bleach, maybe a tablespoon per 5 gallons, when refilling the tank. Michael Brown Windburn C&C 30-1 Listers- My 30-1 has developed a bad odor in the water tank under the starboard settee (the tank that supplies the galley sink). Any tips on how to get rid of it? I'm tempted to pour some bleach in the tank but wanted to check with you all first to see if there is any risk of damaging the material from which the tank is made (fiberglass, I think - the tank seems to be a molded part of the settee). Note I don't drink that water or even use it for cooking. I mainly use it for cleaning. Thanks in advance. Cheers, Randy Stafford S/V Grenadine C&C 30-1 #7 Ken Caryl, CO
