Another garage floor epoxy turned white thread

[rschrader]

Alright... I need some help here.

Epoxy floor, professionally installed, just over 3 years old.

Over the weekend I cleaned the floor the same way I have been cleaning for the last 3 years without issue. Swept out all debris, hosed down floor, splashed a little Simple Green around, brushed down entire floor, hosed down floor again, squeegeed excess water out the garage door.

After drying, I had a white residue on the last 2-3 feet of the floor. I hosed down, and squeegeed again. Looked great until it dried. Hosed down, brushed, rinsed, squeegeed. Same result.

The line appears to coincide with where the sun was hitting the floor. My guess is a Simple Green / water mix dried on this area while I was working on other parts of the floor. It was mid 90s... so my guess is the mixture got cooked on the floor before being rinsed. Ugh.

I've read through some of the other threads about epoxy stains / whitening and have tried vinegar in small areas without success. I have not tried CLR.

Any suggestions?

Thanks!

maybe a floor buffer and some polishing compound?

Wow that is terrible.

When you say residue, can you scrub it away? Have you tried scotchbrite and soapy water on a small spot? In other words do you think it is something on top the urethane or did it degrade the urethane? It also looks like it could be de-lamination but that is a guess based on what I can tell from the photos.

I guess what I'm getting at is figuring out whether this is something on top the floor or something that has somehow affected the floor and ate into it.

Wow. I have the same exact problem. It happens only at the front of the garage that is most worn and sun hits it
