How do I remove the light-brown stains left behind after the successful removal of chewing/bubble gum from broom-finish concrete?


If you used high pressure washing or a solvent cleaner and removed 95% of the gum, normally a high alkaline heavy duty cleaner will finish it off. Mix according to directions and allow 5-10 minutes dwell time. A pump-up sprayer works great for application. Scrub with a stiff broom, brush, floor machine, or autoscrubber, and then rinse or pressure wash again. Steam is another non-chemical approach.
