The Stellar Cafetiere we’ve had in the office is now seven years old and the filter has been clogged with coffee oils and the like for quite a while. Before buying a replacement filter from Stellar I thought I’d look into cleaning products and came across Puly Caff which gets pretty good reviews. Watch the video to see it in action:
So how did it cope on our tough stains? Here’s the filter before cleaning. Note the concentric rings of grime – these line up with the holes on the plunger and so prevent it working efficiently.
The first cleaning cycle turned the bowl of water a horrible colour:
Everything came out sparkling but the filter was still somewhat clogged so I put it through a second clean cycle, this time cleaning the inside of the cafetiere too. Some improvement but still not perfect – it may need soaking for longer than the 15 minutes suggested on the pack:
Update 26 September 2014: Leaving the filter to soak overnight has cleaned off almost all of the remaining coffee gunk. Plunging is now smooth and easy once again!
