Stroheim And Romann

The wallpaper is red, Stroheim and Romann made by. We have tried hot water, hot water and vinegar, and a dilute solution of wallpaper stripper. Nothing worked so far! I called the manufacturer and they say too much time has elapsed to safelt remove glue. It works on all seams and is also present on the surface of the paper. I'll try anything! Thank you.

It's a tough little glue if hot water did not remove it. The glue may have soiled paper it looks. If this is the case, I would go to the shop where you bought it and ask a representative to come and to determine if the product is defective. They will replace the product, and mostly paid for having re-installed. If he has not soiled paper try a solution like removing wallpaper Diffs. It has enzymes that break down the glue, but it is especially hot water you mix with. This is news to me.

you may have to disassemble or try a mixture of paint thinner with a little water in the hope it works for you ...
