First, we carefully remove and mark all screens, and with a soft bristle brush and cleaning solution, clean both sides .
Then, we hand-scrape all windows to remove debris, inside and outside. Next, we use Citra Solve, a 100% biodegradable, petroleum free, non-corrosive, completely non-toxic solvent. It instantly emulsifies oil, grease, tar, and of course the average window dirt. Third, a squeegee is then used to remove the solvent without a trace.
