I have been at this cleaning gig for a long time. I admit that I have used rags (both terry-cloth and micro fiber) to clean toilets. My justification was that if I did not mix them up with any of the other rags that I used in the non-wet areas of the house, I was not passing bacteria. I even went so far as to purchase rags that were a different color and washed those separately.
If you are going to use paper towels for any of your cleaning jobs, this is the place to do it. In the past, the notion of paper towels was that it was wasteful and flimsy. But I have discovered that two full size sheets of Bounty paper towels will adequately clean your toilet inside and outside. They are surprisingly sturdy. http://bountytowels.com/en-us/shop-products/paper-towels/bounty-paper-towels
- Put several drops of Dawn dish soap inside the bowl of your toilet.
- Take two Bounty paper towels and place them in the bowl.
- Wearing plastic gloves, scrub the inside of the bowl.
- Wring out excess water and wipe outside of the toilet and seat from top to bottom.
- Turn the towels inside out and wipe outside of toilet and seat a second time but this time also get the floor around and behind the toilet.
- Throw away the towels.
At this the point, I sanitize the whole toilet with my hand-held steamer but you could use a spray bottle filled with rubbing alcohol. Let it air dry.
No brush, no rags, no laundry, no worries.
