Carpet - vacuum, bought me an expensive one so I might as well use it ( it shampoos as well but I havent learned that yet)

Fiugres wise, I try to play with a figure at a time, like 1 a day - handling them cleans them in a way, but I have to say I am losing on that end heheheh
Shelves, wet-ones and just plain wipes. A bit of vacuuming too once I removed the figures, but this I do like once every 2-3 months as its to troublesome

MOst of the time its just vacuuming the carpet.

If anything keep the lighting in the collection room dim to hide the dust from sight hehahahahah.
