Cleaning

[jokee]

Any advise on what to use to get rid of "yellow" staining on white gelcoat at the waterline. I have tried soapy hot water and a mild bleach - to no avail. Rib is usually landed from berth once a week for a good scrubbing.
Thanks

“Grunt Boat Cleaner”.
Paint it on, leave for 30 minutes, then rub it off with sponge and fresh water. Google it, available in most boat shops

Y-10, paint on - leave for a few mins - rinse off - back to white

Bartenders friend, grunt & y10 all use oxcalic acid as the active ingredient. You can cut out the expensive water & buy the powder from ebay & add your own water. I use it every year on my hard hull boat when it comes out for winter. Add the powder to a bucket of water & brush it on with a soft sweeping brush. By the time I'm down both sides the first area is white & ready to hose off
