I've used splosh washing up liquid for years. Over the past twelve months though the quality has changed. The concentrate doesn't mix with water, leaves a jelly like solid mass at the top of the bottle but not a liquid. I contacted the department, 'Yes, we know there's a problem but just use less concentrate, mix with hot water and that will solve it'. No recompense for a product that was unusuable. Well, the problem has been for a year, it hasn't changed and, after years of using their product I am off to look for an alternative. Shame as they'd been great until then.
