Dedicated loo cloth (that might be stored behind on the pipe). I go from least germy to most germy. Using bathroom cleaner with bleach I start on the cistern and handle, then outside ceramics, then seat, then back of seat, then top of loo and finally, bowl. Finish with brush and Harpic.
Flush, rinsing cloth in the flush, more Harpic and dip the cloth in that before squeezing out and final wipe. No germs survive that.
Sparkly loo.
Another good hack is periodically pour a full kettle of boiling water down the loo and a good squirt of dishwasher, and leave that overnight. That dissolves the stuff in the u bend.
It is also important to teach the boys in the house some etiquette. I do ask them to sit down to pee to save me work (and even husband gets it). No man became less masculine by sitting down to pee.
(Husband also taught the boys this one) after a poo, look down into the bowl. If there is a skid mark, take loo roll and wipe it down before flushing.
The loos are in pretty good nick in the Sutch hovel!
