Bin völlig zufrieden, superschneller Versand brauch die Oxalsäure zum entrosten hat perfekt geklappt also alles bestens
Ich habe die Oxalsäure gut verpackt per Post erhalten. Es sieht gut aus, aber kann die Qualität nicht beurteilen. Ich habe die Oxalsäure gekauft, um zu versuchen Urinflecken am Parkett zu entfernen. Leider ist es bisher nicht ganz so gelungen wie erhofft. Ein wenig heller sind die Flecken geworden, aber vielleicht sind Verfärbungen auch zu extrem. Ansonsten ist die Oxalsäure bestimmt gut und kann den Shop weiterempfehlen.
i haven't received the item yet and it is really frustrating now.
