The more expensive SWISSOL and ZYMOL products as opposed to the Cleaner Fluid, are easier to apply and give a superior finish. They are also two part treatments, the first part being the cleaning of the paintwork with Paint Cleaner Fluid or HD Cleanse, and then a top coat of a high quality wax to seal the paintwork and to give a stunning shine. You then on a monthly basis just 'top up' the wax protection with another coat of wax.
I used some of the Cleaner Wax yesterday on a badly faded whie Polo, and it worked but it was hard work and needed two goes to do it properly. I ran out before I had finished and then used some of the Cleaner Fluid instead. Much easier and did the job in 1 go not two. Then I had to put a wax coat on top but that was extremely quick to do.
I think the Cleaner Wax is a combination of a cleaning fluid and a synthetic wax
At the end of the day, if you want speed and ease of use, then you pay the money.
