Thank you all for your feedback. I appreciate many quick suggestions.
We were able to clean it up using:
1. 3100 PSI Pressure Washer . 2000 PSI was not strong enough.
2. Fine grade Steel Wool - after the washing we needed to clean up some
stubborn particles.
The next step is the tower installation. We need the machine to lift the
tower up horizontally at least 8 ft above the foundation. We are debating
if we should use the excavator to hang it on the hand or some forklift.
This is an older tower 1400 lb
Thanks again
Alex, WK1O
