Known issues and safety
Recall check: we searched GOV.UK product safety alerts, reports and recalls (Office for Product Safety and Standards) for “car-chem” on 19 October 2026. The search matched loosely on the word “car”, and none of the first page’s titles named Car-Chem; we could not check the other pages [2]. Check the list again for the exact product.
Car-Chem’s precautions: wear protective gloves and eye or face protection; if it gets in your eyes, rinse carefully for several minutes and call a poison centre or doctor; if skin is irritated, get medical advice; keep away from children [1]. Measure the dose, since it is very concentrated.
