Borax

[gobbypunk]

More questions ,so in all my yrs of milling I havent ever used Borax never had much of a need to I have been quite lucky with not getting mould on boards until now some of the Monkey Puzzle has grown some very impressive mould its as long as 2inch on a window cill I made from some green monkey puz ,its in a barn  but now I started to use some from the first lot milled and its a bit green in places so I thought I would get some borax ,so my questions are do you just paint fresh milled boards ,will it make any diffrence to boards milled say 9 month ago that have mould .

As always Thanks for your thoughts and advise
