I did exactly the same as the OP yesterday on my ‘day off’. Added issue is my son is into car modifications, so there are boxes and draws full of car bits, except he’s terrible at organising anything – I was fortunate most of his tools were in his car boot yesterday. Went into one of his boxes, and something had leaked, so that meant most of the contents could be binned – yay ! He’s shocking at putting stuff back properly.
Nine bikes in the garage and my five all have a spare wheelset. I’m not too bad on spares, two boxes of parts, plus a couple of shelves with tubes, bleed kits etc. We’ve got shelves full of car detailing products and paint. Biggest space consumer is the camping gear. Big tent, large tarp, camping beds, camping chairs, loo, cooker etc. It’s all stacked up and ready to ‘go’, but it takes up loads of space.
Must bin some of the old hoovers – I usually hang on to the old ones in-case the current one breaks.
