Fertilizer brown stains on concrete.
 

I fertilize some plants few days/ weeks ago, I can’t remember when? I guess I got some on concrete. Had the big brown rusty looking stains. So I got out the DEPS concrete cleaner. Didn’t work, not even straight out of the bottle. so I had some CLR, again scrubbed didn’t do nothing. Started looking for product that might work. Didn’t want to spend 18 bucks for 6 once’s or so, plus said you may have to apply couple times.

Had couple old lemons in bottom of fridge. Why not? I cut them in half and scrubbed the dark brown spots. Pressure washed and walla:MOJE_whot:!!! The spot was completely gone.

So I brought half dozen of lemons for 79 cent piece and removed all the brown rusty spots. :)

Some lawn and shrub fertilizers have iron in them, iron-ex is one and chela mix is another. Hard to remove.

Yep, that’s what left brown spots, the lemon took them right out, if I hadn’t seen it wouldn’t do believed it. I should of took pictures but didn’t think to.

Try dapping the stain with THE WORKS toilet bowl cleaner ! It removes Iron stains... I use that stuff on everything....

Hadn’t thought I’d that? But the lemon worked, hopefully I’ll be more careful next time. Thanks.
