Not much use for removing wallpaper. Whats wanted is steam, or if that's out of stock, very hot water. NT |

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. -- David Clark $message_body_include ="PLES RING IF AN RNSR IS REQIRD" |

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.
