Concrete repair - advice needed

[London GT3]

I have a power floated floor in my garage with a well "polished" finish. My son, bless him(!), left a leaking bottle of alloy wheel cleaner on the floor and it has "burned" two small circles of concrete each about 2.5cm across. It has taken the top surface off the concrete and exposed the sandy aggregate underneath.

Any recommendations for an easy repair to stop it getting worse and smoothing it over again. I accept it won't look the same as the surrounding area.

Thanks.

Bond with pva then a mix of neat cement and water mixed into a spreadable paste should do it, if not it will have to be an epoxy resin filler.

Latex self levelling floor compound will repair that nicely.
I dread to think what it does to alloy wheels, if it eats holes in a concrete floor.

It'll eat through the lacquer on an alloy wheel if left too long.
