Unlock pH guide
Place the agent on the pH scale 1–14
Enter an average pH value (from label/SDS). The calculator places it on the scale and tells you if it is strongly acidic (0–5: descaler/sanitary cleaner), daily/neutral (6–9: universal cleaner) or strongly basic (10–14: heavy-duty cleaner/degreaser) — and warns against acid-sensitive surfaces (natural stone/limestone) and dangerous mixing of acidic + basic chemistry.
