Review: Es tut was es tun soll - Warum habe ich diese Bewertung gewählt? Dumme Frage, weil nach dieser Art der Bewertung gefragt wird. Was mir gefällt? Ich lebe noch, also tut es was es soll. Was mir nicht gefällt? 1. Nicht jeder ist Chemiker, Alchemist oder ähnliches und so ist bei Lieferung erst einmal Unsicherheit angesagt, dem folgt dann eine ausgedehnte Recherche danach, was es denn ist. Grund: Es steht nicht Natriumphosphat sondern TRI-Sodium-Phosphat drauf. 2. Wenn ich Pulver bestelle, dann erwarte ich Pulver und keine "Miniperlen", so dass man es erst einmal selbst pulverisieren muss. Kann ich es empfehlen? Ja. Review: Stain what stain! - Really good! Watched a lad on YouTube use it and he said use an absorbent with as in talc and mix in to a thickish paste so it pulls the stain out! And he also said don’t use a wire brush to clean!,, used talc with it not a chance it was gonna shift it and hosed and swept the paving slab and the bloody stain was still there in all it’s glory :( so today I thought I’m gonna use just this in a cup or warm water and scrub gently with a steel wire brush and hey presto the little bugger has started to fade away RESULT! Don’t use talc because it now looks like someone chucked a bag of flour on my paving slabs but that’ll soon shift with a good hosing down our a good downpour! Fully recommend this product 5* + ## Features - 99 % Pure Tri-Sodium Phosphate - Cleaning agent / stain remover / degreaser.
