Oxalis acid on teak

[Annabel]

I am cleaning my teak cockpit with oxalis acid. Can I rinse off with sea water or will this cause adverse reaction

[Adelie]

Shouldn’t that be Oxalic Acid?

[Dantp]

Probably better to neutralise it first with some bicarbonate of soda mixed with water.
It'll fiz when you apply it.
Then you can rinse off with seawater.
(assuming oxalic acid)

Where is the running of going? As Dantp said its a good idea to neautralise it first

[Tetepare]

Since I’m in fresh water, I ask: if he’s going to varnish or otherwise coat the wood, wouldn’t the salt residue be bad?

[Dantp]

I'd assumed it was going to stay bare teak and just throwing a bucket of the water surrounding the boat over it at the end. (Fresh water no problem)

If you want to varnish or apply other wood treatment then after neutralising I would take a damp cloth and wipe the surface then let it dry.
Make sure the cloth stays clean.
We treated internal woodwork to remove water stains before revarnishing
I hope that's clear.

C2H2O4 + 2NaCl → Na2C2O4 + 2HCl

Since HCl is hydrochloric acid it tends to suggest a bad outcome. I don't know what the other stuff is, looks a bit bicarbonatish.
