Resolving Heavy Mineral Deposit Issues on Glass
We recently have run into a situation when cleaning the glass of a commercial building. After washing the glass it still looked dirty due to heavy mineral deposits on the glass that had appear to have been accumulating for years. Justifiably, our customer was not happy with the results of cleaning the glass. Fortunately, our customer recognized that the issue was not our window cleaning but rather that the glass was in need of more of an intense restore process than a general window cleaning.
We have now prepared a video outlining three separate strategies designed to overcome those mineral deposit issues.
One strategy involves using a solid commercial window cleaning solution and employ elbow grease using superfine 0000 steel wool. This method will greatly reduce the mineral deposits, but will greatly increase the labor involved which in turn impacts the price. However, the chemical is relatively inexpensive, making this the most economical one.
A second strategy involves using a much strong chemical that will actually dissolve the mineral deposits and reduce the elbow grease but still greatly increase the time to treat the glass. This method also carries risk as the chemical can react negatively to certain tin type glass elements and damage the glass. This requires testing each piece of glass before committing to using it as well as the customer signing a waiver recognizing the possibility of the glass incurring damage and not holding us responsible. This method is more expensive than the first method.
Finally, the third strategy is more of a glass restoration using a stain removing and polishing agent that will essentially result in almost new looking glass. The chemical used is expensive and the process is time consuming in that it involves application of the paste using a buffing pad. This will give the best results but will ultimately cost the most.
Another factor is that we are not sure how many years it has taken to get this buildup of mineral deposits on the glass so cannot be certain how often this procedure would need to be performed. Ideally, regardless of which method is used, it would seem that it could be employed in stages rather than the whole building in the same year. In other words perform this effort on 1 or 2 floors per year and do another 1 or 2 floors the next year and so on. After the first treatment, we could inspect the treated glass the next year for signs of mineral deposit buildup and determine if this stage strategy will suffice to keep the buildup under control. Our preliminary thinking is that it should because it seems that what is present currently is the result of a buildup over a number of years. If this proves true it can greatly reduce the cost by spreading the cost of a number of years rather than absorbing the total cost in one year.
We are adding a video demonstrating those 3 strategies.

Water Quality

Recently, we have noticed that our 7 stage filtration has begun producing vastly decreased water quality production. So far we have tried flushing the system for 15-20 minutes with DI water followed by soaking for 24 hours. That had little effect. Next, we replaced the sediment filter and both charcoal filters. Flushed out after installing for 15 minutes and again soaking 24 hours. The water quality has improved, however not to the quality level we expect. We expect water quality before going through our DI to be somewhere between 15-30 TDI but ours was running closer to 75 TDI. So. We’re now concluding we will have to change out our reverse osmosis membranes. They are only a couple years old and we are attributing this premature replacement to not having changed the charcoal filters early enough. The gallon rating for our charcoal filtration is about 5,000. We will now attach a water meter to our system to ensure that when we approach the 5,000 gallon mark. We replace the charcoal filters. We’ll keep you posted.
