dryer cleaning

I read somewhere that it's good to clean the lint trapper every once in a while because residues from dryer sheets can clog it. But for the life of me I cannot remember how it said to do so, other than taking the lint off lol. I have noticed when i remove lint alot stays stuck to it and i can't get it to come off. The article I read also stated something about a good way to see if it had residue build up is to run it under water and if the water doesnt flow right through it needs to be cleaned, hardly any water at all will go through mine. Will normal soap and water do the job or is there something else (for example vinegar) that I need to use? Thanks for any advice.

 

Soap and water and a soft scrub brush will do the trick.
