A couple weeks of winds and heavy rain filled and overflowed the grease pan on our BBQ grill out on the back lanai.
The grease, and carbon char in it, have left stained spots on the lanai's concrete.
I've soaked liquid soap and detergent on it a couple of times while hitting it with a scrub brush.
The stains are not going to be easy to get off.
They have soaked into the surface, penetrating the concrete, the carbon intensifying the stains.
Any good ways to remove grease stains from concrete?
As long as I'm looking at working the lanai's concrete floor, gasses evolved by the eruption we had 2 - 3 years ago, are being washed out of the air by rains and have damaged the lanai and walkway's concrete surfaces by dissolving the surfaces exposing the sand and gravel aggregates.
I'm considering refinishing the surfaces, over 600 sqft.
Having to etch the surface and apply a new coating while exposed to weather, complicated by our being out of a drought into a wet period.
Because of the exposed sand and gravel, the surface is much darker.
Thoughts and suggestions for getting a smooth, even surface and color doing this?
