Soda or Sand added to water for Surface cleaning

[Mardie]

Hello i am new to this board am am trying to educate myself on the ways to use pressure washing for flat surface cleaning ie. concrete/asphalt. I do not have any equipment yet. What is your take on using Soda or sand when using a surface cleaning tool such as a spinner ???

I really think you should do some reading of older posts here. None of that is needed or used through a surface cleaner.

I bet the bearing would have a very short life at 2 to 4 hundred dollars a pop.

You can get a soda blaster attachment for a pressure washer, sand as well. That pulls it thru at the gun. Never thought it necessary for concrete and kind of a pain to use. It has its own gun. Would never use with a spinner.

Soda or sand blasting is not needed unless you are removing paint, old adhesive or other coatings, not needed for regular concrete or asphalt cleaning.
