Every few years you should do a tune up on your gutters and downspouts such as re-secure and re-pitch gutters, reseal corners, reattach loose downspouts and elbows.
Check to make sure your splash blocks are angled so the water flows away from the foundation of the house. Please do not angle them towards any walk or driveway since this could cause a slipping hazard.
The cleaning solution can be either sprayed or sponge applied with a soft bristle brush. Allow it to remain for 15 to 20 minutes, then rinse with a hose. Rinse thoroughly. Avoid skin contact or getting the solution into your eyes.
Caution: Greater concentrations may cause damage to the finish. Never use abrasive or solvent type cleaners or paint removers.
