If you use water, blot the window dry with a microfiber cloth after the dirt has come up.

Don’t rub the window with the microfiber cloth as this can cause scratches in the acrylic.

Good non-abrasive cleaners for this type of cleaning are castile soap, baby shampoo, or Woolite or Dreft.

If you’ve never buffed a surface before, proceed for gently with this step.

This technique should only be used for very, very deep scratches.

Using a buffer after you sand acrylic can give your acrylic an extra shiny finish. This technique should only be used on unfinished acrylic or if your acrylic windows have suffered extreme damage from storms.

You should avoid using wire brushes or scrubbing pads as these can scratch the acrylic and ruin it.
