I go to my DMums and declutter (it is a work in progress and feels like the Labours of Hercules crossed with Painting the Forth Road Bridge) !
I'm sure she has things hidden that she brings out of cupboards as soon as my back is turned
DMum is a hoarder and DDad doesn't like throwing things out just for the sake of it (I have to persuade him that "No, the Charity Shop do NOT want that , no-one else will use it . They will just throw it out which isn't fair on them so we will bypass it" ) . Not 'rubbish' but just things they will not be able to sell.
So:
Three Bags
Bin
Recycle (paper/plastic)
Charity Shop
Pick something up, decide and put it where it has to go (even if this moves later) don't just put it back where it was if it was in the wrong place.
Be ruthless but be sensitive that some things ( sentimental value) you want to keep. Can these be used ? Why keep something for best when you can use it now .
Once the bag is full, either put it in the bin or the car (so my DMum cannot go through it and empty it out over the kitchen floor )
Vacuum, dust, clean with a (nice smelling) spray and cloth .
I did blinking loads last time I went , I am confident it will be a repeat next time.
