How do I get the residual concrete to release from my yard sale concrete
tamper? One of those two handled things with the 8" x 3' bottom screen.
Probably paid too much for it ............... $10. Spray with vinegar
water? Soak overnight in plain water? Spray with some sort of petroleum
product like WD-40 and let soak overnight.

Then hit with power washer? Or just power wash?
