Every window cleaner has one soap they keep coming back to. For a lot of people in the trade this is it, and the 5 litre jerrycan keeps you going for a while.
Panama is thick, so you simply dose it with the cap, straight onto your washer or into your bucket. No mess, and no half a jerrycan going in by accident. On the glass you get plenty of foam right away and it holds for a long time, with the rubber gliding over it nicely. The degreasing power handles dirty glass, frames and everything in between.
The soap was originally developed by a pharmacist for general use. No dyes, no fragrances, biodegradable and very economical. That shows in your running costs, and it is a lot kinder on your hands when you work with it every day.
Working with a fixed crew or cleaning every day? Then the 5 litre jerrycan is the obvious choice. For lower usage there is the 1 litre bottle.
