Also, for any chastity wearer, I recommend this for cleaning while still locked (between removals)
Water Flosser Portable Oral... https://www.amazon.com/dp/B0756DSWWK?ref=ppx_pop_mob_ap_share
It will let you get into the nooks and crannies, inside the cage, between your cage and balls... To gently rinse. Don't use soap in it..
Someone with a more open cage that can air out better can use this and pretty much never remove for cleaning.
Best tool for cleaning is something like this:

It's a water flosser, meant for flossing your teeth. But, that one is made for travel, camping. No power. It works like a water pistol. Fill it with water, pump it up, and it squirts water out the tip.
It's perfect for getting INTO the cage. Just don't put soap in the flosser. Use it with just water to rinse everything out and make sure you get all the soap out of the cage.
