Lots of misinformation here, At least AD28 looked up the glen Raven cleaning
Bleach is fine on canvas
, make sure you rinse throughly.
The stitching is not affected, uv is the cause of stitching failure along with rough zip use and flogging.
I have cleaned a lot of boat canvas
items, including sunbrella plus fabrics and get great results with the Vacuwash process.
Some tips I give all boat owners, canvas is a maintenance
item and needs to be cleaned regularly, just a hose and a sponge is better than doing nothing. Do not use a pressure washer or a hard brush. Soak the canvas to get bird droppings off. After cleaning
you must reproof with a product, glen Raven recommend 303, I use mclube sailkoteplus, but anything is better than nothing.
Canvas is designed to breathe, so make sure that there is air flow to help prevent mould from starting in the first place.
Canvas is also an expensive bit of kit on your boat, so it does pay to look after it.
