Hello, I have the WEPOS 00005 shower cabins cleaner already used a few times. The cleaning effect is above the average of traditional bathroom cleaners. Very impressive is the water-repellent effect. This is the first and only known to me bathroom cleaner with water-repellent effect, the more than fulfilled his promise. Thank WEPOS !! The effect is so great that my wife excitedly came to report, like the water in the shower drips off me. You did not know that I used a new cleaner. Finally I found the cleaner, with which a shower cleaning takes exactly 4 minutes. However, it is recommended that the old (if available) to treat lime stains with a special Kallöser ago. With everything else these cleaners copes very well.
