More likely accumulated in ICW
, rivers and gunkholing, the brown tannin stains can be easily removed with the proper chemical wash. These stains often form a "moustache" on the bow. There are several very expensive hull
cleaners sold for this purpose at near $20 a quart, but if you compare the active ingredients, you can find the same effective cleaners sold as common toilet bowl cleaners for about $2. I was looking over a recently revived post about using toilet bowl cleaners in the marine head
and I was looking for this application, but it was not mentioned. I do not use the acid wash toilet bowl cleaners in my head
, but I've found them very effective for cleaning
my freeboard tannin stains. I usually apply the cleaner with a sponge and let it sit for about ten minutes before a thorough rinse. My original 1973 white gel coat still looks good and I've found no negative effects from this type of cleaning
. Do many others use this plan or have alternate techniques.---opinions?
