I have an older 35 foot Chris Craft Catalina that has a few little leaks and because of the way the bilge is designed I always have a little bit of water in the bilge. I recently started having a problem with mold in the cabin and on the soft top canvas enclosure at the helm. I tried a few different products to remove and prevent the mold from coming back with varying results. I had unbelievable success with Concrobium Mold Control. This isn’t a paid review, I am just so happy with it I thought I’d share my experience.
Mold control comes in an aerosol can, spray bottle, gallon jug, and a fogger. I used the aerosol can version on my boat. They also sell a Mold Stain Eraser. I didn’t have to use this product as the Mold Control I used took the stains out without needing anything else.
I started cleaning the canvas and vinyl at the helm first. Spray the Mold Control onto the entire affected area and wipe with a clean terry cloth rag. That’s it! For me I only had to spray the area, wait a few minutes then wipe the damp area off with a rag dampened with the mold control. My canvass and vinyl looked brand new! For this post I wish I had before and after photos but I didn’t think to take them at the time. The way I did it differs slightly from the directions on the Concrobium website but it worked great for me. Mold Control also helps prevent mold growth and odors. If the area treated is regularly exposed to water, retreatment with a light coat may be necessary every so often. My canvas hasn’t needed retreatment this year and I did the original application in may of this year.
I have used Mold Control on just about every surface of our boat since I have a serious mold allergy and am very sensitive to mold and musty odors. I treated the walls, carpet, A.C coils in the air conditioner’s, Drain lines for the A.C units, finished wood on the boat, the head and shower, and the headliners in the cabins. It didn’t discolor any of those items or surfaces and so far only the A.C coils needed a re-application of the product. As always test in a hidden area first before going hog wild and spraying everything down. I’m interested in buying the fogger for next year and treating the entire boat at once. I did read one online review that said while the fogger works great you have to wipe down all the surfaces right after using it and that you have to be careful with fabric surfaces as it may leave residue.
They also have Moisture Grabbers that are suitable and recommended for boats. These combined with good airflow and fans will help keep your boat’s cabin and closed areas mold free. I keep a small fan running 24/7 on my boat to improve airflow on days we are away from the boat. You might also be interested in solar powered deck fans that you can rig to keep air moving in your bilge.
The boat smells and looks much better and is a healthier place to be now!
