I've done it several times already so don't need any how to advice on that but I hate doing it as now I have my grinder I'm using it all the time. My question is this... I'm going away for a few days next week so it'll be getting a rest and I was debating leaving the descaling powder in it while I was away to give it a really good clean out. Has anyone done this? Is it safe to do? I'm worried the acid will start eating into stuff it shouldn't if left too long.
