Muriatic acid, 50/50 mixed with water in a throw away hand spray bottle. Takes only SECONDS. Be ready to rinse it well quickly. Maybe even toss baking soda on AFTER rinsing to neutralize the acid. Works great on sprinkler stains on the side of your house too. But be ready with the hose to rinse it within seconds,because it will dull some paints.
Citric Acid also does the job in a shorter period of time (almost instant, you just need a scouring pad) Glacial Acetic Acid for just letting it eat at it with minimal scrubbing
The CLR brought the rust up but then you mashed it back into the concrete when you scrubbed it. Just wipe it away or throw some water on it. Don't mash it back in then use a paper towel to smear it all over.
I'm trying to clean some geodes up too and looking into using clr but I am hesitant cus I don't know how well it will work but I also don't want to damage them. How well did it work for you??
The result was the result of scrubbing not by the CLR. CLR should have sit there for several minutes to do its job but it was not able to do so because you scrub and rinse it immediately. Duh.
Should pour the CLR on the stain. Let it sit for 30 minutes then rinse off with water. No scrubbing.

Whats the best product to remove clay/ dirt? after doing my backyard the mud , mainly clay have left stains where i cant seem to remove...grr
You’re supposed to let it sit for awhile then start scrubbing 🧽
Good for you! Don't follow directions, don't think it through, just action and failure. Next...
My thoughts exactly
I thought you had to leave it for 2 min. after you pour it, then start scrubbing it. Then rinse it with cold water. Right?
Saw CLR commercial on the christian channel, just used It in calcium and lime in the sink...BAM! Worked great!
Praise the lord!!
Science at work
The lable says to leave on for 2 mins without scrubbing

Spray (DWELL TIME 2-3 Mins) Scrub a little > Rinse Cold Water
Oh you may need to dilute in warm water.
Just use a acid, phosphoric is more then enough for very tough stains like this or vinegar for light spots.
Citric Acid also does the job in a shorter period of time (almost instant, you just need a scouring pad)
Glacial Acetic Acid for just letting it eat at it with minimal scrubbing

PMC05 dish soap mixed with vinegar apply liberally with sponge, let sit for awhile then rinse.

It is painted concrete, you can't do that on a regular non painted slab.
CLR is a waste of money backing soda with vinegar is way better
Just use vinegar and a wire brush!!!!! 🚾🚼
