The waterproofing is already worn off though and i need to do another coat for this season.
Can you wash a boat cover in a washing machine. Cleaning your boats canvas cover A dirty job like this might have you reaching for the pressure washer but the powerful jet can damage the threads of the canvas. If it is a breathable polyeter fabric then it is quite possible it will need to be re-waterproofed and you wont know until you do it. If you get too aggressive.
Over time it can damage both the water repellency and the cover itself. Never put Sunbrella fabrics in. Thanks for the question.
Make sure the cover is zipped closed before you put it in the washing machine or you may end up with a tangled up mess. I start with the cover inside out. Wash it on gentle cycle in cold water with a mild detergent.
Some of these you dont want to use high-heat. If the top or boat cover is suitable in size for a washing machine these steps should be followed. Wash and rinse in cold water.
Covers can be line-dried but many people prefer to put the cover. Wash and rinse in cold water. For best results choose the gentle or delicate cycle option.
Add the required amount of detergent to the washer and fill it with cold or warm water. I could clean all the spots but it is 110 degrees today at noon and even though I have the top inside I am lacking any motivation for work. Especially when you got to dry them so make sure you follow the instructions.
