How to remove discoloured marks on outdoor tiles?

someguy2k

I had a rust marks previously on outdoor tiles shaped of a round circle ( probably caused by a pot plant from previous owner). I scrubbed with some bar keepers friend and a toothbrush to remove the rust marking ( in hindsight should use other methods instead of barkeepers friend). Now I see this ghosting mark where the cleaning and scrubbing occurred.  Any possibility this can be reverted/fixable ?

Thanks

Hi @someguy2k 

If you  feel there is a remaining rust mark  try using CLR  ( Calcuim lime and rust remover)

But to my eyes you now have a reverse of a dirty spot you have  bright clean spot. You may have to ultra clean it some  more to disipate the pot outline (blur the outline to be less obvious,  more of a cloud shape) 

Basically you can  go to a lot of trouble and scrub that floor so the whole floor is ultra clean to match that clean spot  Which will get  dirty again with time any how.

Or you can use some regular floor cleaner a couple of times mopping over whole floor and it wont do a perfect job in fact some of the cleaning water will re stain the ultra clean spot and moderate its appearance all gong well.

The trick I think is to polish out the remaining circular shape and make it less  distinctive feathering out the ultra clean.  Try  using a  polishing disk on a drill,  Angle grinder specialized polisher,  car polisher to make your life a little easy.   If you use some thing like gumption it has a little powder in it to help polish things  clean and simply use less cleaning pressure further out  from the clean spot.

Its really annoying getting  clean spots.
