Good/clear flux to work with 400 centigrade Sn63 Pb37?

Looking for a flux that does not turn brown at 400 centigrade temp...

NC559 in the syringe, not the fake China shit. Louis has it for sale on his website.

Also 400C never happens, lead-free solder melts at 225C max.

I have purchased it right after he started selling it on his website. Been using it since then, the only thing I don't like is when I am wicking soldering pads on a board using 400C on my soldering iron with wick..it turns brown and hard so fast..I need to constantly clean it..

What wick? Some wick has its own flux built into it and it's terrible. Try goot wick.
