Do de-acid sprays like this work without wrinkling or damaging the pages?

Is this worth the big price tag? Will the fluid wrinkle the pages? Regular water sure does. Anyway to make a homemade spray for cheaper?

UPDATE: I received a reply from a user on reddit about these kind of sprays. He said that it is not advised to use these sprays on personal book collections. Apparently these sprays do have uses in a library context. Here is what he said:

"Do not do this. I use bookkeeper deacid spray professionally. It leaves a deeply unpleasant texture on all surfaces it’s applied to, it needs to be applied extremely well to work, and it’s not clear that in the long run it actually does much more than storage in ideal conditions. It also doesn’t restore any lost strength from acidic deterioration when applied: if you apply this to a brittle book it remains brittle."

I see that magnesium oxide is the active ingredient in these sprays. I'm wondering if anyone has experience making your own spray instead of buying the expensive brand name sprays. Magnesium oxide appears cheap. From the MDS disclosure sheet I see these ingredients:

less that 0.5% Magnesium oxide (MgO)
less that 0.1 % Dispersant (Proprietary)
greater than 99% Methoxynonafluorobutanes

That is why it's so expensive. The main ingredient is an expensive solvent. (Warning: Don't breath it in or get it on your skin or in your eyes.)

Don't do it to books that are either your regular reading copies or have any value. The bookkeeper process is well known to leave a deeply unpleasant powdery residue on books that have been treated. I should say, well known among librarians. Bookkeeper itself strongly denies that this happens, which is hilarious.
