I use a foam brush and position the blade over the glass bowl of vinegar and start by loading up the brush with vinegar and start brushing the blade. I keep the liquid moving constantly. It usually takes over an hour of brushing until I get the desired effect. I neutralize the vinegar with plenty of soapy water and oil. Sometimes it’ll take more than 1 session to get where I want it to look.
Like I mentioned, it’s a lengthy process, it’s a labor of love.

There are vinegars with higher acidity, up to 20% that I have seen at home improvement stores. I m sure they work quicker but I stay away from them.

Thank you, I will give it a try. After many hours of polishing, an hour brushing doesn't sound so bad. Dunking when you can't remove the blade presents a lot of challenges, great to have an alternative.
