I just found the BEST thing for soot:Originally posted by Scott
What cleaner is the easiest to use for the black soot on the transom Is this stuff the ticket or is it for the scum line?
I want a spray on and wash off type product if possible. Too many parts and hoses on the transom to try and wipe something on.
Black streak remover. Spray it on good, rub it with your wash mitt and 99% is gone.
The ringo works great as a follow up. Afterwards, the transom will look like new.
I gotta tell ya, I've tried EVERYTHING trying to get rid of the soot. I just happed to srpay some black streak remover on the soot by accident. Didn't even rub it; I just sprayed it with a hose and noticed this big white spot!!!!!
Try some, it works wonders.
