Hi! I'm new to this or indeed any forum - and a woman - so don't get too technical. I have a problem. I have Neville Johnson white oak kitchen units installed about 20 years old. I stained them about 7 years ago with Sadolin White stain which was OK. It appears that it is no longer available and I cannot find a substitute. I want to see the grain on the units. I do need it to be quite heavy wearing. Please help.
