Can any one suggest a cleaning method for removing mildew from a canvas cover.

Can it be cleaned in a washing machine with cold water and mild detergent?

Thanks in advance.

I had a problem with some canvas backpacks I kept in my basement. A friend told me to use TSP mixed with water. It was very effective in killing and removing the mildew. I used a spray bottle and a damp cloth. Good luck.

Trisodium phosphate-available at any hardware store. Used for cleaning walls and siding prior to painting.
 
Bleach like Clorox works well. Dilute solution and make sure you use plenty of fresh water to rinse it well. Air dry in the sun if you can. You said you can put it in a washing machine. Add the bleach to the machine and run it on cold with some laundry detergent. Air dry in the sun, if you try to put it in the dryer, it might shrink up some and not fit as well.
 
I agree with SilverBullet. I take my bimini down; go to a public laundry; put my bimini in a large commercial-sized washing machine using cold water, Woolite detergent and bleach. It then gets air-dried and coated with 303 Fabric Waterproofing/protectorant.
 
Did just that at the local laundry using Oxi clean and came out looking brand new.

Thanks

Q&A

Q: How often do I need to thoroughly clean Sunbrella?

A: The best way to keep Sunbrella brand fabrics looking good is to simply clean them as needed. Rinse off dust and dirt, wipe spills as soon as they occur or spot cleaning soon after stains occur. Removable cushion covers may be machine-washed in cold water with mild laundry soap and air dried. For more stubborn stains, Sunbrella fabrics are bleach cleanable.

Q: How do I clean my top/canvas?

A: Your top fabricated with Sunbrella fabric is easy to clean and maintain. The key to having a beautiful top for a long time is to simply rinse your top (and boat) after each use with clean water. This prevents build up of dirt that is hard or impossible to see. Then occasionally your top will need a thorough cleaning, which once again, is an easy project for the boat owner.

Q: How do I remove mold and mildew?

A: Sunbrella fabrics will not support the growth of mildew, but dirt on the fabric will promote mildew growth, which makes regular cleanings important. Mold and mildew can be cleaned and removed from Sunbrella fabrics. No set timetable exists for when fabric should be cleaned, and the local environment has a great deal to do with determining cleaning frequency. Cleaning is required less frequently in a dry environment than in a humid one with heavy foliage.

BTW: If you wash your canvas cover or bimini, put it back on the boat while it's wet and fasten it down so it doesn't shrink when it dries.
