We have been in our home forty years. At the recommendation of our neighbor, we called the Blue Wave team.
Three young men arrived on time and started unloading what look liked floor polishers. I was very concerned about my plants so I asked them to only use water, no bleach of any kind. Before I knew it, they were working their magic with those scrubbers. When they did the final rinse, I was SHOCKED! GREAT JOB!!!!! Our driveway is gorgeous.
When my driveway needs cleaning again, I will definitely call Blue Wave, but this time I won't wait 40 years!!!
