WINDOWS :
* NEVER use a Powerwasher - although the strong jets of water will get them clean easier and faster, that same strength has the chance of breaking the seal on your insulated panels, and may damage the sealants that prevent your window from leaking. So strong, that the simple use of one will void the window's warranty with most manufacturers.
* DO NOT add aftermarket window film - if your insulated windows contain 'lowE' or other energy upgrades, (most that were installed after the year 2000) installing this film will interfere with the those upgrades and cause the interior of the window to heat up, melting the material used to seal the insulated unit, allowing air and other small particles to get between the panes of glass. Once this moisture and debris begin to intrude the glass will start to fog in extreme weather, and the LowE coating to start to change color. Although it's no great issue in the beginning - over time the panel will be less and less transparent, less energy efficient, and eventually possibly become a health issue due to mold.
* Periodically clean the weep holes - This video will explain how weep holes work, and how to clean them. Failure to do this may lead to water collecting in the track and spilling over onto the windowsill in bad weather, and may cause your windows to Appear as if they are leaking. If cleaning the weep holes doesn't resolve your issue, you can perform a water test to determine if the leak you found is the window's fault.
Bathroom Enclosures :
Mfg Applied Coatings : Many newer enclosures have an upgrade available that is advertised to "make cleaning your unit easier and longer lasting". It has many names, as each Supplier gives it their own. (Clear Shield, EuroShield, just to name 2). This coating is baked into the glass at time of manufacture and will encourage water to flow off the glass leaving less spots and water stains.
Harsh Abrasives : There is no right or wrong 'gentle' cleanser to use, but over time the harsher you cleanser is, the more likely it will eat the sealants that prevent water from escaping, and deteriorate the Mfg coating. We recommend using a squeegie to remove standing water on the glass after each use, rather than switching to stronger chemicals.
Tabletops & Shelves :
Heat - Always use a trivet or other barrier between extremely hot items and the glass. Many homeowners don't realize that the glassware they use on their stove and oven are not actually glass, but a combination of glass and clear Ceramic giving them heat resistance that your tabletop will NOT have. 'Temper' will add only a little - and not enough to prevent the glass from shattering if something too hot stays on it too long. If you can't hold it in your hand for a 10 count - Use a Barrier!
