Re: OT Garage floor paint etching the floor

What Ralph said. Using hydrochloric acid is somewhat hazardous.

I have some doubts as to whether or not the citric acid etcher would be strong enough to do much actual etching. The pH of organic acids is higher than that of hydrochloric and other "mineral" acids - so the rate of reaction w/ the concrete would be slower.

You should be fine. People have been using hydrochloric acid to etch floors for years.
