You could always just use bi carb?
I did strip wash probably every 3 - 4 weeks & after anything like thrush or gastro to make sure they were extra clean.
Direct sunlight & I've also heard of putting some lemon oil on any stains? Never tried it though.
Oh i shall try the Bi Carb, since we got bulk of that here lol.

Im not using cloth untill this lil girl comes as DS is TT now.

I always put DS in direct sunlight.. never got stains or tried the lemon oil tho.

thanks
