UK recommended detergents are not working

[CelesteJA]

I bought and tried the detergents recommended by the creator of this wonderful rewinder, but they just simply don't clean my dishes. Seems to work okay on non-stick pans, but plates and cutlery are being left with food smears stuck to them.

I noticed there's a difference in PH levels between the original bob formula and the recommended replacement; the original bob formula has a PH 1, whereas the recommended replacement has PH 2. Not sure if that's the reason it's just not cleaning my dishes?

Has anyone had any luck finding a good replacement detergent and rinse aid in the UK? I'm pulling my hair out over this, I've been searching for ages.
