Wand/Pressure Lines in Concrete

[buc21jrs3 14]

Any suggestions for removing a few wand lines in concrete? Unfortunately my surface cleaner (rotory head) died right over a clients front walk yesterday and left a few pressure lines in the sidewalk. They are noticable now that the concrete is clean. Is there any way to fix this? I was going to use a wand but he wants me to wait until the surface cleaner is fixed before I come back and finish the job. Thanks in advance

Try blending more with the wand/clean in opposite or multiple directions overlapping the spray.

Use a detergent or brightening agent like rust-away, that will help or just wait until your cleaner is fixed.

I will try this next week when the cleaner is fixed and let you know the progress. Thanks!
