STEP 1: Determine the type of sealer the concrete has. Before you can clean concrete, determine what type of sealer was applied, if any, since it can affect the appropriate cleaning methods.

And if you happen to have unsealed concrete floors in your basement or garage, you probably have better things to do than wash them on a regular basis (if ever).

Steel is concrete’s best friend, as it adds enormous tensile strength to concrete slabs. If your building code permits it, be sure to include floor drains in your garage.
