I just changed the resin and now I just need to clean the brush. But I can not see white stuff on the brush from the unger paste. Is it invisible for my eye?

Soak the brush in pure overnight, then rinse it off, should clean it out

I did a full day with 063 once, the vessel itself was broken but anyway I expected to receive some phone calls from customers but when I went round the windows were spotless!
