This has been an excellent all round cleaner. I bought it to tackle algae and moss build-up, which we get quite a lot of in rainy Somerset.
In particular, the citrus cleaner diluted 6:1 was really effective at removing the algae that had built up behind the boot hinges, you could really see it cutting through dirt that even IPA wipes had struggled to remove. I also used it to remove sticker adhesive from a glass panel that other solvents had failed to shift, I was astounded at how quickly and easily it removed it.
I used it at the same dilution on fairly heavily soiled alloys and, again it loosened the brake dust nicely and is a great alternative to higher strength alloy cleaners for regular cleaning. An added bonus is that it doesn't seem to be excessively solvent-y, so is very pleasant to use.
The value for money is very good when you consider the dilution ratios.
