Hard Water Stain Removal
Hard water stain removal in Marietta, GA starts with an honest fact most cleaners won't tell you: Cobb County's tap water is soft. The Cobb County–Marietta Water Authority reports treated-water hardness of about 31.7–35.1 mg/L — roughly 2 grains per gallon. So the white mineral crust on your glass almost certainly did not come from your kitchen tap.
In Marietta it comes from well water, irrigation and sprinkler overspray, and pool splash — untreated sources that hit the same panes day after day and bake on in the Georgia sun. That distinction decides whether your spots will clean off, and what they'll cost.
Stage 1 spots vs etched glass
Fresh mineral deposits sit on the surface and usually lift with professional stain treatment. Old spots, left for seasons, can etch into the glass itself — that damage is in the pane, not on it, and no cleaner can honestly promise to reverse it. We test-spot one pane first, show you the result, and quote per pane from evidence, not optimism.
Fix the source, not just the symptom
If a sprinkler head is painting your picture window every morning, cleaning alone buys you a few months. As part of the visit we'll point out overspray patterns, suggest head adjustments, and flag which panes to watch. Our blog post Cobb County Water Is Soft — So Why Do You Have Hard-Water Spots? explains the whole picture.
Safe on historic and modern glass
Acidic stain removers are used carefully, kept off frames and surrounding materials, and never left to run toward planting beds or storm drains. For original single-pane and true-divided-light windows in Whitlock and Kennesaw Avenue homes, we use the gentlest effective method and hand application only.

- ✓ Test spot on one pane before quoting
- ✓ Per-pane pricing from the test result
- ✓ Sprinkler / well-water source check
- ✓ Gentle hand application on historic glass
- ✓ Rinse controlled — no runoff to storm drains

Every job is quoted free and firm before work starts, and stands behind Resiclean's 100% satisfaction guarantee. See honest market pricing on our cost guide and what customers say on the reviews page.

Questions
Hard Water Stain Removal — common questions
Straight answers, the way we give them on the phone. Anything else — call Dillon at (770) 846-5651, open 7 am–8 pm · 7 days a week.
Ask a question →Surface deposits, usually yes. Spots that have etched into the glass over years cannot be fully reversed — we'll prove what your glass can do with a test spot first.
Adjust sprinkler aim, and put affected panes on a maintenance plan so deposits never get a season to bake in.

“Dillon did an excellent job pressure washing my entire house, driveway, and walkways. In addition, he also did an amazing job cleaning all of my windows to include the big large window sitting high above my front door.
Patricia TurnerGoogle review★★★★★
“I only called for an exterior window cleaning but they gave me an amazing price to also add on gutter cleaning and to have my entire property pressure washed!! I couldn't be happier and will definitely be calling them next time!
Andrew HigginsGoogle review★★★★★
“Resiclean did a fantastic job cleaning my 20+ windows. Dillon notified me of his approximate arrival time. He arrived on time... Resiclean is fast but thorough. I highly recommend Resiclean, and I booked my appointment for next year's cleaning.
