PoE Orb of Scouring is usually a currency item that may be applied to get rid of all random modifiers from magic or unique piece of equipment. Implicit modifiers, high quality, sockets, and hyperlinks are indeed not removed, as well as affixes protected by meta-crafting mods. Exile Orb of Scouring Removes all properties from Poe item. Generally turns the item into a Standard top quality item with no features. However, sockets and hyperlinks are usually not regarded as properties of an Item, so those will keep there untouched. There are not a lot of uses for this Orb except for meta-crafting. Unless you feel like you might be eventually carrying out that, really feel free to sell all of those

NO.3 When using Orb of Scouring
Utilized Orbs of Scouring a couple of times so far. The critical use of it appears to be if, for example, you locate a magic item with fantastic sockets, but it is only magic. You can use an Orb of Scouring to remove the magical affixes and return it to normal, then an Orb of Alchemy to turn it into a different item, making it far more highly useful and valuable than it initially was.
Whetstones/Scraps are also a lot more productive on ordinary items than on magic/rare items, so it is worth it to Scour an Item back to normal, enhance the excellent, then use an Orb to return it to its former level. Of course, you won't want to do this if it currently has outstanding affixes, as the odds of receiving them back will be pretty much nil.

NO.4 Use Orb of Scouring on maps
High-quality increases by 5% per corresponding excellent increasing orb utilized on white, 2% per blue and 1% for rare and above and maps past a certain level (IIRC 72and above) are worth exalt +
In the event the map dropped as uncommon and has really shit rolls like a combination of (mobs have GMP + Chain + deals 100% Dmg as lightning + elemental weakness on map + -23% max player resistance ) , its 101% worth it to scour it to white and chisel it 4x as opposed to 20x as rare. Blades are worth about 5 = a piece of GCP at the moment, so you save like 15 tools worth by scouring it and Alch-ing it once more following blades! 
Similarly, you might get some 67-68 maps like sewers and spider lair which are commonly worth doing in blue and maze-Ed. It dropped in uncommon with some crazy stuff, and you might as well scour it merely because contrary to beliefs - a lot of people who spam promoting maps wind up trading away maps like ghetto, arsenal, dungeon, wharf plus the likes! 67 maps like sewers you will desire to alt and locate a maze as opposed to spending chaos upon chaos simply because it is base worth don't warrant chaos-es.
Naturally, persons are also using scourings on things like glorious plates and changing them for Koams. One more situation that one particular could consider of is a 6-L white imperial bow dropped (hugely unlikely obviously), and an individual wants a 6-L Lioneye glare one of a kind and likelihood and scour it.
Hopefully, these are some scenarios that you will encounter even though playing the game at the map-level that'll encourage scouring uses - likely why you do not see a great deal of them until merciless because to new players it may appear lackluster at first glance.
