How should I clean under the narrow toilet rim to restore full flush power?
Someone told me to drain the tank. Then put duck tape over the holes under the rim. Add your cleaner of choice to the tank, (I poured directly into the bowl filler part as I was &quot;flushing&quot;). I used CLR. Let it sit for 30 minutes. Opened up the holes pretty well. Did it again. Flushes like new. I have HORRIBLE water, rust, iron ect. Give it a try. This is not spam, nor do I want to spent hundreds to replace it.
