High heat can turn the light plastics into golden or yellowish colors also! If you store any Playmobil in attics, commercial storage buildings, garden sheds, etc., especially the older vintage type, make sure to do as much as possible to make the atmosphere as climatically controlled with systems such as thermostatically controlled ventilation fans, air conditioning, etc. as possible.
More money spend in maintaining a collection in mint or good condition rather than the collection itself...but, its an investment!!!!
are you sure it's the heat the proplem or the dust ?? i think the dust is the problem because this is making them dirty and so changes the colour
Absolutely, all my playmos are in a 45m2 srorage room and shelves all round and also a few hundered books .. There is zero dust , no sunlight and the air is refreshed daily and tempreature is maintained at room temp at all times. no humidity . Thje books , boxes, magazines, klickies, other toys are stored in good condition this way. i have the storage room next door another 30m2 , separated by a a thin non supporitng wall, might destroy that wall to creat more continuous space and more surface area for klickies !!!!!!
High heat is the problem! I had a 3525 that I acquired MIB , cleaned it from dust after displaying & returned it to storage later,concealed in a 2 gallon zip lock bag, in its original box to discover the dreaded yellowing of the light grey parts later !
These Nuremburg guards look very nice!!!I have some myself which I'm about to restore to after seeing your results!Mine have all the older unmoveable red hands.
