As opposed to the other Swedish chemist named Arrhenius, who did not receive a Nobel, but did discover yttrium.

And Spotless Stainless is really good.

I've found better results with the warm weather here in Florida cleaning any rust. Collinite, Spotless Stainless, On/Off, all work better here. Attitude is better, too.

FSR - Fiberglass Stain Remover - is a 4.5 % solution of Oxalic Acid. Comes in a gel formula.
Its also the main ingredient in teak cleaners and oddly enough can be purchased in its alias which is Cascade dishwasher gel.

If I remember granger is a Professor of Chemistry. So I defer to him. Anyway, I spent most of my time in Chemistry class with my cheek firmly planted on the desk with drool running out of my mouth. I do NOT want to revisit pKa discussions....
Oh!

THAT was you?

I must be guilty.
Don’t get me wrong. I’m glad there are people who understand pKa. I just don’t want to be one of them.
Guess what i’m not doing now ….:snooze:

muriatic and sulfuric will dissolve the tannin stains also, very quickly, which is due mostly to the strength of them vs the lemon juice or vinegar....
nylon can be damaged by exposure to moderate strength acids, so be aware of what may be made of nylon on the boat, and try to keep it protected.

I use acids quite often for different things... muriatic, sulfuric and mostly hydrofluoric, and in the strengths I use them, they will all damage your clothing and skin.... different acids do work differently on not organic objects.
getting any industrial strength acid on your hands and not washed off before the pain starts, the acid will soften your fingernails to the point that the fingernail gets a yellowish hue and begins to turn into a gel, and your fingerprints will be eaten from your fingers..... and then weeks of pain and healing with chance of permanent nerve loss..... but so far my fingerprints have always grown back....
"A Boat, like a Woman, likes to look Good and be Noticed.. " The similar quote is; A Boat is like a Woman, requires plenty of powder and paint. From days of old the powder was gun powder.

Hi all,

Our rafting mate was spraying his boat with lemon juice and the ICW Stain was running off. He mixed his half/half. We went shopping for ourselves and mixed it 50/50 in a garden sprayer. The brown stain came off without scrubbing, no gloves or respiratory protection needed.

The beauty was we got the juice at the Dollar Tree for a $1 a bottle.

Old thread, but it points to something about dollar stores.

16 oz for 1$. A little low in citric acid, about 4%. so 0.64 ounces citric acid, or $1.56/ounce.

Citric acid on Amazon is about $0.31/ounce, or 5 times cheaper. It is packaged to seem like one.
