So I’ve been using warm soapy water to clean the old glue off and it works okay, but last night I tried this bicarb spray and it works even better imo

Only thing about that I would worry about right off is the abrasive nature of bicarbonate of soda.

The glue stick literally washes off with just water, there’s no need for more.

and its salt. ie rust. But most dishwashing detergent is high in salt anyway. I wash it then wipe it with clean fresh water then a mircofibre cloth to dry it.

get the high temp plate and you dont need glue at all for PLA and PETG, thats the reason in the first place for a flex plate … i hate that messy glue stuff

ahhhh i see. i bought the hot plate as well but havent used it. Its not too messy for me tbh. But still early days for me hahaha.

compared to no glue and just wipe the plate after print with IPA its way more messy 
I thought about that when my friend bought me this spray to clean my kitchen (!) but surprisingly the grain is seemingly none existent. It’s meant for cleaning glass surfaces etc so I imagine it’s so fine that it wouldn’t bother the plate. I’ve used it a few times with absolutely no visible swirling or scratching. I imagine something like this sold in America though would probably be a lot harsher

I’ve got the textured pei sheet, it works great but it means the internal fan comes on like a jet engine. The machine is a ton quieter using the cool plate

bicarb is a rust inhibiter, check your science lol
Well, 
I think you might need to check your own mate, Sodium, (SALT) and carbonic acid (self descriptive) thats what bicarb is. Bicarbonate of soda.
Sodium bicarbonate appears as odorless white crystalline powder or lumps. Slightly alkaline (bitter) taste. pH (of freshly prepared 0.1 molar aqueous solution): 8.3 at 77 °F. pH (of saturated solution): 8-9. Non-toxic.
Sodium bicarbonate wiki;
Sodium bicarbonate, commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO₃. It is a salt composed of a sodium cation and a bicarbonate anion. Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda. The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.Wikipedia
Heres an abstract from a study on Bicarb and corrosion.
Abstract I cut it down but feel free to google.
The effect of bicarbonate concentration (HCO3−) on bare steel surface corrosion was investigated,… Thus we have demonstrated that bicarbonate is an [active corrosion] species and is important to corrosion at pH 6–8. (mild dish soap ph 7~8)
Our earlier mechanistic corrosion model (Han et al., 2011a) was modified to incorporate bicarbonate-induced corrosion and demonstrated good agreement with experimental observations.
.
How do i know this?
I mix it with other chemicals to make instant rust for scene effects.
TLDR…
its a salt. It makes metal rust.
Rust is the reaction between iron and oxygen. Oxygen is present in air and water. Oxidation is an electro chemical reaction that is facilitated by some chemical solutions and inhibited by others. The bicarb soda NaHCO2 in solution is Na+ and HCO2- … the bicarb ion will make water slightly basic and inhibit the process. Water acts like a minor acid even in pure form but with salt ClNa present this process of acidification is facilitated further and the reaction with oxygen is quicker.
Google bicarb as a rust inhibiter you will find all the answers you need. There’s different forms of salt…
Peer reviewed or credited sources?
Or is it situation where the skys purple because you and google says it is. Because there’s plenty of that around particularly on renovation forums where they know lots of everything except chemistry.
If youd like to conduct this experiment yourself get a piece of sheet steel place it in water that you’ve added a decent solution of bicarb into. Or that spray for example un diluted. Given time it will rust above or below water. Paint it in bicarb water mix and let it air dry and eventually it will induce staining and corrosion, so best to rinse it off with fresh water.
Its Corrosive when mixed with water,
its sodium. Na. yes ok slightly different to NaCl
Its also used on food to tenderise due to it being salt.
anyway here is a link to a peer reviewed article that conducts the research and concludes that based on the information provided in the article, bicarbonate can cause corrosion on steel.
Again, I use it along with many other propmasters designers etc to induce corrosion and staining on metals. Not all metals but definitely the same metal as used in the sheet.
Hey maybe that scientist and his entire team and findings were wrong? Feel free to let him know. Im sure there are specific circumstances where it would inhibit, but in the terms of 3d printing, heat, high airflow, exposure to other chemicals such as glues, filaments etc etc. Given time, and bicarb, it will rust.

Water is what causes the rust, salt combines to accelerate the process because it makes the water more acidic. Bicarb makes the water less acidic so…
I think rust is one thing people talk about, but I think corrosion is more important because it contains much more problems. I would never work with salts at technical devices if it is not necessary.
We worked at some projects with automotives and a local producer of salts. They had corrosion at all sorts of steel and at their aluminium parts (for example from NaCl and water). The local Producer uses tubes of a Titanium-alloy and they always find traces of titanium in their salt-water.

yes agreed, corrosion is a different story, bicarb will cause corrosion on softer metals like aluminium
Well agree to disagree, I could go on for hours about this as i know it promotes corrosion from first hand experience. The research by myself and others back me up here. I cant help but think however, If bambu go to the trouble of printing use detergent to wash on their build plates and specifically state use only warm water and detergent in the manual. Id shy away from anything else TBH.
Also if you look on the back of that bottle or on their website which I just did, it specifically states " Avoid contact with mild steel or aluminum surfaces. " Likely due to the fact that bicarb being only the scent or secondary ingredient used in that bottle, meaning the primary solution is probably caustic or corrosion or stain inducing if not cleaned off.
However if you still don’t believe me feel free to read on;
Here are some further quotes from reputable sources backed by the scientific community. The following quotes from suggest that bicarbonate solutions can induce rust on certain metals:
- “A sodium bicarbonate solution showed a significant increase in the corrosion rate of iron and steel, as compared to a sodium chloride solution (SALT WATER ) at equivalent chloride ion concentration” (Source: Journal of the Electrochemical Society, Vol. 153, No. 5, pp. B170-B176, 2006).
- “Bicarbonate additions increased the corrosion rate of low-carbon steel. The corrosion products consisted mainly of FeO(OH) and Fe(OH)2. The corrosion products formed in the absence of bicarbonate consisted mainly of Fe3O4 and γ-FeOOH” (Source: Materials Science and Engineering: A, Vol. 489, No. 1-2, pp. 25-34, 2008). (So rust but a slightly diferent molecular formula, Id like to keep it simple and say … rust.
To summarize, both studies suggest that bicarbonate solutions can increase the corrosion rate of certain metals, such as iron and steel, which can lead to rust formation.
and just because im bored, to further your recent response, While it is true that the presence of water is necessary for rust to form on metals, it is not entirely accurate to say that water is solely responsible for rust formation. Rust is a complex electrochemical process that involves the reaction of oxygen, water, and metal ions to form iron oxide. There is many different forms of rust as previously shown in that study, again keep it simple lets call it all , rust.
Furthermore, the claim that salt makes water more acidic and bicarbonate makes water less acidic is not entirely accurate in the context of rust formation. While salt can increase the acidity of water by introducing chloride ions, bicarbonate can actually increase the alkalinity (i.e. reduce the acidity) of water by introducing bicarbonate ions.
However, the alkalinity or acidity of water is only one factor that can influence rust formation. The presence of certain ions (such as chloride) in water can also accelerate the rusting process by increasing the rate of corrosion. Who knows whets in that Wilko solution ( I cant find the safety data sheet to check either)
Therefore, while it is true that water is necessary for rust formation, the claim that bicarbonate can prevent rust formation by making water less acidic is largely oversimplified and does not take into account the many other factors that can influence rust formation. Therefore, its safe to draw the following conclusion, use at own peril.
I suppose your technically spot on Christian, , rust is more commonly known than pitting etching staining and corrosion, For this arguments sake, and probably an oversimplification, but my point here is that spray is not good or recommended by the manufacturer, or the supplier of that chemical Wilko, it even states, not for metals. It was by far easier for me to say rust in general than to say FeO(OH) and Fe(OH)2, pitting staining and potential corrosion.
I’m not introducing other factors though
p.s I will keep you updated on the survival of my build plate
you can just turn it down to like 50% when you open the top, and then its way less noisy
