I need advice -

I used a cleaning product (I can't remember exactly what it was) about a year ago on my garage floor which, in hindsight, I shouldn't have used or used improperly. It appears the product was a little too harsh and the floor is now deteriorating slowly, pitting and such. I'm not sure if I used too much without diluting it or I shouldn't have used it at all.

Can someone recommend something to counteract what is happening to the floor?

Thanks

Sounds like you used some form of mild acid - perhaps you failed to rinse or neutralize it.

I'm just guessing, but I wonder if a solution of of baking soda or lime would neutralize it.

If they used acid and didn't neutralize it, the damage is done and can't be corrected.

This is why I hate to see acid being sold in hardware and home improvement stores. Most people don't know the proper way to use it safely or even the fact that if should be neutralized after applying it.

What the OP can do is pressure ash the area and then top coat with a cement base product or apply a sealer.

Not sure of the hole size damage but what I did one time was to sprinkle some concrete dry cement...swept with a broom and then sprinkled with water to make a watery paste. Started from a corner working my way backwards to the outside door using a broom and the next morning was able to walk on it.

In regard to any oil stains...volcanic fine dust will bleach like you would never believe.

In doing a red brick area out front of my place...I'd allow a small space between them which I filled in with the dry cement...sprinkled some water and brushed the surface clean....quick and easy.

They make concrete pactch for filling holes.The sopread sweep and water works fine for light patios cracks between pavers but i would trust it for small holes on a concrete floor really.

I did rinse it.

I'll try a solution of baking soda and/or lime and hope that can stem some of the future damage.

Thanks!

Before taking further action, you might want to get some litmus paper to test the floor's pH (i.e., junior chemistry set kits can work for this). If you get a very acidic (red) reading, you'll know you've got to neutralize the (likely) muriatic or hydrochloric acid previously used on the floor. If you get a basic/alkaline (blue) reading, then you probably cleaned with a caustic soda of some kind. In either case, this will give you better information and help you avoid using the wrong remedy.
You may also want to consider having an epoxy resurfacer installed to repair the situation and save the slab from further damage. I've been in the biz for years, so feel free to contact me if you need some recommendations. Good luck!

Where would one acquire volcanic dust? I Googled it, but could only find beauty products with that as one of the ingredients.
