Securit Liquid Chalkmarker Pen Cleaning Spray 500ml - Remove Residue Liquid Chalk From Blackboards & Chalkboards, Paint Marker Cleaning Spray, School Supplies - Glass Cleaner

Expensive but does the job, I tried everything to remove the waterproof chalk pen from glass and this was the only thing that worked.

Cleans chalk pen on blackbaurds very easy👍

Works great. Got rid of the ’ghosting’ left by ordinary chalk and shifts liquid chalk which was impossible to erase using just a damp or dry cloth. Pleased with this product. Expensive though.

Very good product. Cleans chalk from chalkboard quickly and easily.

I bought this to remove chalk pens. It doesn’t remove them completely like shown on the video. Fades them, but not remove. Works wonders on my mirrors, however, £15 just to clean them and not what I bought it for. Worst thing I’ve bought is those pens, they look nice, but spent £25 on products just to remove. 🙄

Ok

Doesn't work.

Terrible. Won’t clean chalkboard markers even if I leave the spray on for 15 seconds. The picture shows how much came off after multiple sprays and scrubs - I feel conned!

Si riesce a togliere qualsiasi scritta con i pennarelli waterproof senza lasciare residui.

impeccable. Parfait pour les taches sur le tissus de mon canapé

O melhor

Pas convaincue

Perfetto per cancellare dalla lavagna le scritte fatte col pennarello impermeabile della stessa marca, basta spruzzarlo sulla carta e rimuove facilmente i tratti
