Guy who wrote it is describing cleaning the very high volume restrooms at the Orioles’ Camden Yard.

Salient points are:

1) Use a grout specific cleaner – he uses a hydrogen peroxide formulation (as do we) but there are others.

2) Dwell time is important !

3) Pressure washers and or cylindrical brush cleaners are recommended.

4) Use a grout specific floor sealer / impregnator – normal vinyl or concrete seals are not as effective.

5) Two applications of sealer.

6) At least 48 hours “curing time” before wet mopping the floors again.
