Hard water, limescale, aglae and even salt can all form stains on glass over time. The best way to stop this type of damage, collectively referred to as mineral damage, is to clean the glass regularly with clean soapy water.
Once glass becomes stained it is very difficult to remove by just washing it using traditional methods. A polishing action using a mild abrasive compound is usually the most effective way to remove mineral stains from glass.
Repair Solutions: for large areas or multiple units
If you have a large area or multiple units to repair, our advice would be to call a professional glass polisher. As they say, time is money and this includes your time.
It would be misleading to try and give a general cost of repair on a website as each scratched glass situation is different, but for large areas of scratched glass or for multiple units, services of a qualified glass polisher offer genuine savings, often in excess of 80%, on the cost of replacing scratched windows and doors.
For areas greater than 50 sheets of A4 we would recommend you ask for a senior technician to visit your site to assess the works required and provide a written quote.
The Cost Effective Option. On paper, professional glass polishers are not the cheapest glass polishers on the market, but the reality is that a Guild qualified glass polisher will repair a least twice the area than that advertised by most others othering scratched glass repair services. This makes our members extremely cost effective and our members are still the only glass polishers able to guarantee distortion free repairs.
Repair Solutions: for small areas or single units
For smaller areas or for single unit repairs, employing a professional glass polisher may not be the most cost effective option. You might find that a D.I.Y Scratched Glass Repair Kit would be a more cost effective option for you.
A quick note about D.I.Y Kits. There are a number of kits on the internet that claim to remove scratches from glass. Please be careful. Kits with just a felt pad and polishing compound will not remove anything other than very, very fine hairline scratches. The same can be said for kits containing 'Jewlers Rouge', polishing powder, usually pink, which you mix with water.
