Portafilter and shower screen cleaning after each shot - process?

I think my shot making process is pretty "smooth" up to the actual brewing, but afterwards, I have no quick way and easy way of cleaning the portafilter and shower screen.

After emptiying the puck of my portafilter, the filter still has so much wet coffee grind (2-4% of original amount) so that I need to run it under the tap to get it away, which is not optimal since my sink is in another countertop.

After the shot the group head shower screen is also smothered with coffee grounds, so that I need to use a tower/paper to take it all away. Using paper feels like a waste and has me needing to access the trash, and using a tower is just messy.

What are your preferred methods of cleaning the portafilter and shower screen after each shot?

Portafilter basket: https://www.bluestarcoffee.eu/easy-clea ... 9482-p.asp This brush is very small, but the pic shows the size against someone's very small hand and what I guess is a 49mm portafilter. This is just an example; there are many such brushes available.

Shower screen: On a machine/basket/dose that I can use a puck screen, I use that to keep the screen relatively clean between shots. Othewise, I'll run the group for a couple seconds and then wipe with a bar towel or use a group head cleaning brush, e.g., Pallo's https://coffeeaddicts.ca/products/pallo ... hine-brush (again, many such brushes available). At the end of the day/session I'll use a group head brush or an Espazolla if it fits

I would think my puck is too soggy/messy to use only a brush for cleaning the portafilter. Do you experience that you get all the old coffee gone or do you just go on with some coffee residue when preparing the next puck?

What size (in grams) is your basket? And how much ground coffee (in grams) do you use for a shot? Have you done the coin test to ensure that the amount of coffee you're using is appropriate for the basket? It sounds to me like you might have a sloppy puck because your basket is too large. If I'm correct, getting the basket size correct is the primary factor in getting a nice dry puck to drop cleanly out of the portafilter.
I typically can simply wipe the basket with a damp towel and refill from the grinder.

I hold the portafilter underneath (not locked in) and run a blank shot to rinse the screen and pf. This takes care of the residue between shots. I also use a puck screen which seems to keep the shower screen pretty clean.

I rarely get soggy pucks these days. If the puck looks like it exploded and the shower screen looks a mess - then that could be indicative of too big a dose for that basket. That is probably the most common reason - unless there is some mechanical fault with the machine like the three-way valve being dirty/partially plugged/plugged. Can you get dry pucks with a lower dose?

I used to always get soggy pucks with traditional single baskets shaped like this one: https://www.espressocare.com/products/i ... gle-basket
However, I no longer get soggy pucks in those types of baskets by using a puck screen. I use this thin one that I think was first made by Coffee-Sensor so I can maximize dose: https://coffee-sensor.com/?s=Second+cof ... pe=product
However, most folks use a thicker sintered one made famous by Bplus, but now ripped off by many other companies: https://www.bplus.biz/products/lower-sh ... uck-screen
