How to remove leaf stains

[brad900]

I have a garage slab poured last sept. During construction leaves built up in some spots & stained the concrete. I tried to pressure wash & scrub the stains but they are still there. I will be putting down Legacy Industrial HD-6600 matte sealer so I need to remove the stains. Any help would be appreciated

The tanin in the leaves makes a pretty good stain. Oxiclean should do it with some elbow grease.

I have some leaf stains in my garage floor also. They are memories of times past, not a blemish on my floor.

It would make a nice design, oak leaves, maple, etc...
We had a customer do animal tracks once.

CLR is what I recommend to installers. Jelmar is one of the producers. Calcium, Lime and Rust remover. Seems to work well on leaf stains.
