EC 90 vs. EC 95
The EC 95 is a powerful universal cleaner and the best on the market for the watch/jewellery sector for cleaning polishing pastes and carrying dirt. However, the EC 95 is also corrosive and therefore not suitable for aluminium and soft stones.
For sensitive materials the EC 90 is generally the product of choice. This neutral power cleaner is also very well suited for cleaning polishing pastes and carrying dirt.
