Deep Clean Coffee and Tea Micro-filter Cleaning Powder, 4.4 Ounce

it actually works as advertised!!!! My espro looks as almost new & shiny- highly recommend this.

Excelente. Un poco caro, pero sirve muy bien.

I wish I'd taken a "before" pic because it almost completely restored my years-old and heavily-used P1 travel press to new. I washed it after every use, using detergent and a brush like the very old instructions said, but it almost looked copper inside by this point. In 30 minutes of soaking the tea filter in hot water with a teaspoon of the ESPRO cleaning powder, inside the press (the P1 is 500 mL), the insides went from a steampunk residue I couldn't scrub off with a brush and soap, to pristine silvery stainless steel again. The tea filter mesh is silvery again too, and the plastic is black and shiny with no filmy residue. The force to press the plunger dropped significantly. The only parts it didn't entirely restore were the silicone seals around the top and bottom of the tea filter. They are visibly cleaner (including under the channels they sit in around the basket), but not white like a new one. Very glad I bought this and wish I'd noticed this existed sooner.

Does it job: removed heavy tea stains from my french press internals

Works like magic! My filters are just like new. It eats away all of the build up making it easy to press.
