     Before cleaning any surface an inconspicuous  

area should be cleaned to test spray pattern 

and distance for maximum cleaning results.

     If painted surfaces are peeling or chipping,

 

  use extreme caution as pressure washer may 

remove the loose paint from the surface.

     When using on surfaces which might come in 

contact with food, fl ush surfaces with plenty 

of drinking water.
