I recently bought for the first time a used lot from my neighbor who is a real estate picker with hoarding tendencies (and probably not the best hygiene). The lot I bought was most likely left outdoors (unsure if covered) as I found chunks of leaves and other debri in the bin. However, taking a small glimpse I quickly noticed some intact pieces of some star wars ships and made an offer on the spot (FOR DIRT CHEAP...litterally). After bringing it home and leaving it in my garage I was able to confirm by the minifigures I picked out on what I had scored. However, looking through most of the Lego and intact pieces it was pretty dirty and grimy, and some were just plain disgusting. Also as I was cleaning the minifigures I did find a live and dead bug (praying its not a flea). But I'm telling myself...Lego is Lego
So here are my questions for those who do buy used Lego and can help answer anything:
1. Can you spray down lego with organic insecticide (peppermint smell) and re wash them later?
2. What is the best way to clean this and if it's worth the time to do it?
3. The minifigures I found (only 1 or 2 had a crack torso) had extremely stiff joints but seemed to be in very good condition. Is the stiffness caused by environmental elements (heat, cold, etc)?
4. Would you sell this dirty lot to someone else as is after thoroughly picking out the minifigures?
5. Would you attempt to rebuild these star wars ships knowing how much they can resell in the aftermarket? Looking at just certain key pieces (cockpits, Lego colors, etc) it seems like most is there.
6. Do you skip buying these type of lots because of how poorly the used Lego were stored? Have you ever bought anything in this condition?
The box on the right are the intact pieces I picked out...the box under (30x21x11)


is still full with Lego, non Lego, outdoor debri and possibly living or dead bugs.
Here's a sample list of what is possibly in this lot...
Star wars: 7263, 7251, 7252, 7255, 7257, 7261, 10144, 6210, 7658 + others
Thanks. I appreciate any feedback (besides not writing a entirely long story).

2 & 4. Well, it depends really on the person. I can handle dirt. Leave the lego in soapy water for 2-3 - 5 days and it will clean (stir them every 12 hrs or so). But if they also smell.... Then its a big no no for me. Yes i did get such a lot. Picked out maybe 0.5 kg of pieces and minifigs before i got so grossed out, that i could not bare to touch them again. So sold them further for 5$ per kilo, mentioning that i sell pieces not broken down sets.
3. Possibly (maybe dust or rain water too)
5. The important / expensive ones yes. Small/medium ships not really.
Find the minifigs, are they all in decent condition and complete.
Identify the set, and check its price. Is it worth my time sorting it out assuming it is all there?
Check the inventory for expensive parts, can I find them?
Start sorting by part type.
If I stop at any stage, I sell off minifigs and expensive parts individually. They might actually be more valuable than the whole set anyway if sold individually. And you don't have to sort cheap parts and can sell them off as bulk.
When tipping the water away, I have a bath hair stopper to prevent smaller parts going down the plughole, and a large fine sieve is useful both for getting the last of the water without parts out of the crate and for rinsing off the soapy water. Then I scatter them on a large towel and leave to dry. May do more than one pass if the lot is particularly dirty.
After they've dried, a microfibre cloth and light pressure with used toothbrushes does well.
I pluck out the stickered parts first but any I've missed seem to survive with no change anyway.
Also for 3 - the arms can get dirt in the socket but water doesn't always get rid of it so you may need to remove the arm to get them cleaned.
It is a lot of work, but also why its typically cheaper to buy a typical LEGO lot than one that is sorted by color and clean already (and has instructions books and the figures and what not). You have to like it a bit and not think of it as a chore or else you may as well not do it.
Also if it is left outdoors or cat piss dirty, I'm not sure I'd want to keep the stickers anyway.
