Wow... great topic and great images... I have several crates... just shop vac or vacuum with the soft brush and wipe down... careful with too much water as the wood may expand and cause damage to the ink/painted graphics as they may lift off.
JKL, I had no idea that collecting crates was even a thing! What a great variety you have of different brands and of different variations of the same brand! I have to keep my eyes open for more in my hometown...and when I travel!!!
