Not hairspray, unless you enjoy having it on everything in the room where you spray it. Use the gluestick included with the printer!

I personally think the glue stick provided with the printer is not good enough for details prints. You need something stronger. I stopped using after a few weeks of owning my first UM2. I need to try the hairspray thing, but if someone is so stupid to spray hairspray all over their room rather than two puffs directly into a tissue as shown in neotko's vids then that should be a lesson to them. Its like asking someone to not use the glue because they might get it on their face, lol.

lol!
I do it over the kitchen sink. Or I do it the neotko way and spray on tissue. But usually I use wood glue as shown in my video above. I show all three glue techniques. Even with the glue stick, after putting some on the glass I use a wet tissue. Watch the video
Another interesting technique which I have not tried is to use salt (salt water). It sounds like it works pretty well but I haven't compared it to glue.
Edited by GuestFor PLA I only use the "salt method": moisten a paper tissue with salt water and then gently wipe the build plate. Gently keep wiping while it dries. So there is a very thin and equal, but almost invisible mist of salt on it. But not too much.
For colorFabb PLA/PHA and Ultimaker PLA this gives a very strong bonding when hot (60°C), and no bonding at all when finished and back at room temp. This makes removing the parts very easy, as it requires no force at all. For ICE PLA the salt method still works, but no longer perfect: corners do slightly lift sometimes. Fans can be full on, as required for PLA.
No need to take the glass out of the printer, no need to clean it. Very easy.
I don't know why, but a paper tissue works better than a sponge. Maybe because it distributes the salt in finer drops than I could do with the sponge, so it gives a better covering? But this is a guess.
For PET I also got the salt method to work now. But I had to increase build plate temp to 70°C and use no fans. Otherwise corners lifted a lot. Now it gives a reasonably strong bonding when hot, and very little when cold. Here, without salt, the PET is more difficult to remove when cold, so the salt somehow helps in releasing. It is not perfect, but works good enough.
I have tried the dilluted wood glue method too for PET: this gives a stronger bonding than the salt method, so it could also be used with fans on, but it was way more difficult to remove the print after completion and cooling down. Once I even pulled a big piece of glass out of the build plate. So I will keep this "dilluted wood glue method" for high models or delicate prints that need cooling, and use the salt method for low and sturdy prints that can do without fans.
For ABS the salt method did not work, but I did not try very hard. I disliked the horrible smell of ABS too much, and it sort of reacted with the salt (or with the moisture in the salt?) and started to foam terribly the first two layers. I did not investigate this further. Maybe I will try again in the future, maybe not...
By the way, apart from the bonding, keep the default settings to start experimenting.
For PLA: 210°C nozzle temp, 60°C bed temp, 100% flow, 50mm/s speed (20mm/s for the first layer), 0.1mm layer height (0.3mm for first layer), etc... And good bed leveling, not too high, not too low. These defaults are good, so that should work well enough. If it fails, it is not because of these settings, and there is something else wrong.
Clean the glass with whatever window cleaner you want, or alcohol. But then clean it once again with pure luke-warm tap water only! Some window cleaners or alcohols do contain chemicals or soaps that do reduce bonding, so you have to remove these too afterwards.

I will defy give salt a try seeing as i already have some at home. Im still using glue at the moment but i get some tiny areas that lift up slightly, not to bothered but when it get too bad ill try something else.
