0 Pat Norman 18 Report post Posted May 4, 2013 (edited) Pics? May need a strong solution applied with a Chem pump or xjet. Yeah the tsp substitute with sodium metasilicate would be helpful. Pat Norman 662-316-7685 Edited May 4, 2013 by Pat Norman Share this post Link to post Share on other sites

0 Pat Norman 18 Report post Posted May 4, 2013 Just fan it out some and back off. Don't hit it too hard. Pat Norman 662-316-7685 Share this post Link to post Share on other sites
0 Chazz 14 Report post Posted May 5, 2013 I bought the TSP substitute, it comes in a quart size plastic bottle. It says to add one cup of bleach to the quart in a plastic pail and apply 3-5 mins and not to dilute. But i will use my x-jet and scrub with my extended pole... Hope it don't take off any paint on the stucco and i must not get it on the windows Share this post Link to post Share on other sites

0 Pat Norman 18 Report post Posted May 5, 2013 Is your tsp substitute a powder or liquid? Pat Norman 662-316-7685 Share this post Link to post Share on other sites
0 Pat Norman 18 Report post Posted May 6, 2013 Not familiar with that. I would take a five gallon bucket, put in 3 gallons 12.5% bleach, two cups powdered tsp substitute and fill with water and xjet on the bad spots. Downstream the rest.

0 Craig 111 Report post Posted May 7, 2013 Have any F9? I've had guys just spray a little on black streaks and wash off. They came out right away. Share this post Link to post Share on other sites
0 Chazz 14 Report post Posted May 8, 2013 Tried everything in my bag of tricks, i only faded the stain Customer and i did not have high expectations. We agreed for half the price i stated, he was happy with the rest of the house and front gutter. I hate it when that happens but i have to be realistic Share this post Link to post Share on other sites
0 Guy B 70 Report post Posted May 9, 2013 F13 should do the trick, if that doesn't work you could try an acid, but the F13 should do the trick. Share this post Link to post Share on other sites
