I've just read all around the question about 'clutch power' from nine years ago and the changing molds, both here and on Rebrickable, but these don't answer my problem.
Has anyone else had the problem of bricks and plates not wanting to stick to plates being used as base plates? As in MILS plates, for example? Often they just slide over the plates not wanting the engage, especially when I'm trying to stick a structure with EG a footprint of 6 x 4 studs onto a MILS plate. I'm using a mixture of new and I don't know how old.
Anything I can do about it? Wondering if I should wash everything in lemon juice.
