Our kitchen cabinets are about 5 years old now and starting to squeak, some of them awfully. They have European-style hinges (KraftMaid is the cabinet brand and I guess these are Blum hinges). I'm an old hand with good old WD-40 and the trusty straw, but not these sorts of hinges. For the life of me, I can't cure the squeak. I have squirted WD in every crevice where I think there are moving parts, but the squeak persists. What am I missing here? Could someone point out where to stick the straw in these darn hinges, please? I hope disassembly isn't required to be able to get at the right spot in these hinges!
