Default does sugar soap deteriorate with age?

just trying to get old wallpaper paste off the walls so i can just paint them. been scrubbing with sugar soap, but doesnt appear to be shifting it particulary well...

just wondered if it goes off with age, as this is stuff had in the garage for last year or so... it doesnt seem to pong as much as i remember??

any advice?

thanks

its only soap powder. Not much use for removing wallpaper. Whats wanted
is steam, or if that's out of stock, very hot water.

Agreed. Plus lots of clean rags (or keep rinsing out the one you have).


He's not trying to remove the wallpaper though, just the remaining paste.

Sugar soap removes grease and is ok to remove static grime, but not
wallpaper paste which is pretty much starch or equivalent; soaking with
hot water is best.

Sugar soap may be scented, and this will be fugitive, (if you can smell
something it must be at least slightly volatile) but the underlying
surfactants are relatively stable with respect to time. Are you using hot
water? The compounds used in modern (i.e. the last 20+ years) are
appreciably less soluble in hot water than cold.

The old starch pastes required cooking up to solubilise the starch. Then
along came cellulose ether types which needed pouring into hot water to
prevent clumping and being left to cool with occasional stirring. Then the
technology came along to coat the cellulose with glyoxal, which dissolves
relatively slowly, allowing the powder to be added to cold water and be
stirred for a few minutes until the paste was ready. The latest
generations are based on starch ethers, a chemically modified starch
requiring no boiling, just stirring into cold water. The high-strength
types may also contain redispersible PVA powder. I will leave the readers
to fathom why the market leading (when I worked in the field) Celacol WA
was so designated.

Which is why he needs water or steam to soften the paste, plus clean=20
rags to make sure he's taking it off and not just spreading it around.
