Πουά είναι ο τοίχος μουυυ!!! Ιδέες;

According to the Blu-Tack website the best way to remove Blu-Tack
stains is to use a citrus-based stain remover but this will generally
only remove faint stains. In my list of links at the end of this
answer I have provided some example products that may be of use (but
you may also have something in your cleaning cupboard that will work
just as well). You should be able to find a suitable cleaning product
in your local supermarket or hardware store by looking at the
ingredients. These types of cleaner usually list d-limonene as one of
the ingredients.

I have also included a list of links to recipes for homemade
citrus-based cleaners, which I would use at your own risk!

If the walls have been painted for some time and the posters been up
for a number of years, the oils in Blu-Tack are, according to the
official site, "sucked out" by the porous nature of the old paint. If
this is the case the only solution that Blu-Tack.com provide is to
remove with sugar soap and repaint the area.

If you have any further queries on this subject please ask for
clarification and I will do my best to respond swiftly. Good luck
with the move!

Εγώ συνήθως τα βγάζω με μια σπατουλίτσα. Έτσι τουλάχιστον δε φεύγουν κομμάτια τοίχου.
Καμιά φορά επίσης μπορείς να κάνεις πως τα σβήνεις με μια γόμα ή με ένα μεγαλύτερο κομμάτι να τα "τραβάς" από τον τοίχο.

Καλή μετακόμιση!
