Fairy liquid wont harm your car at all providing its only used to aid wax removal

As already said its actually quite hard to totally decontaminate a car once its polished and waxed well

I use a combination of Farecla G3 Detox, Fairy liquid, APC from Sainsbury's and a Bilt-Hamber clay bar...But if polishing afterwards...that process will remove any previous residue anyway

Ok thanks all.

CarPro Eraser?

Tried it..Its good but doesn't remove everything ........BH Clay bar and APC sees off the residue

Used the Halfords Pressure Washer Shampoo and BH clay.

Overall underwhelmed with the results but will put a new post up.

Paul.

I really like both and have excellent results

You really need to use a polish after using any clay as it usually marrs the paint slightly...then add your LSP to finish
