Exhaust stains
 

For cleaning the exhaust stains off of the baot, I've found out that Zep Orange cleaner / degtreaser works well.

I bought a gallon at home depot for somewhere around the $9 range a while back.

I have some full strength in a squirt bottle for the exhaust, or any heavy stuff, such as grease, or oil. But I also have it diluted and use it to wash quite a bit of other stuff too. Can't remember if there are any precautions on the bottle (of what not to clean) though. I guess it would be comparable to simple green, but It seems to cut the heavy stuff a little more.

I've found it's a good all around cleaner that's relatively inexpensive.

Just thought I'd mention it..........................

I just found the BEST thing for soot:
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!!!!!:eek: :eek:
Try some, it works wonders.

Hey stop following me around:D
Where did you find the black streak remover and is that really the name?

Yes that's really the name.
West Marine, BoatUS, or just about any other boat supply store.
