Removing hard water spots from outdoor windows can be a very difficult and time consuming task. Pair that with the fact that many household cleaners are not powerful enough to remove irrigation water, well water and hard water stains and that household cleaning chore becomes even worse. Luckily, Scum Off is specially formulated to remove hard water spots with soft water conditioners. It is best to clean your windows on a cool day, or out of direct sunlight.
1. Use a garden hose to spray your outdoor window.
2. Apply Scum Off full strength onto wet window using a stiff bristle brush. Use about 1 tablespoon of Scum Off per 4 foot x 6 foot window and scrub in a small circular motion.
3. Let the product sit for 10 minutes (while it is on there the patented water softening agents are "scrubbing" to remove the hard water spots)
4. Use the wet bristle brush to quickly re-agitate the windows before rinsing them off with a garden hose. The water will sheet off with no wiping, squeegeeing or hand drying making this an easy and fast process.
Scum Off has a 100% lifetime guarantee. If this product doesn't work to your satisfaction, you can return it at any time for a full refund.
