600 Detergent
by: David

Dear Jim,

You should be able to get that cleaned off with 600 Detergent. After every job, we have a light gray haze and the 600 Detergent gets it cleaned off.

Since you're in Colorado, you should go to Rio Grand and Sand. They are at:

201 Santa Fe Dr
Denver, CO 80223-1328
(303) 825-2211

They have all of the cleaners that my dad uses for situations like yours. Give them a call and they should be able to give you the best recommendation.

Great luck!
