SGG BIOCLEAN Self Cleaning Glass

Congratulations on choosing SGG BIOCLEAN self-cleaning glass for your glazing. Please follow these maintenance instructions carefully for best results.

What is self-cleaning glass?

SGG BIOCLEAN self-cleaning glass has been specifically designed to remain cleaner for longer than standard glazing.

How does self-cleaning glass work?

A transparent hydrophilic coating on the external surface of the Self-Cleaning window harnesses the power of ultra-violet (UV) rays and rain water (or water) to break down dirt and grime and then wash it clean away.

The coating is totally integrated into the surface of the glass and is highly durable. However, as with all coated glass a certain level of care must be exercised when handling and maintaining SGG BIOCLEAN.

Guidelines for initial contact with SGG BIOCLEAN


If the SGG BIOCLEAN label is still attached to the glass, carefully peel it off. Care must be exercised when removing the label from the glass to ensure that the Self-Cleaning coating is not damaged. Do not use a razor, scraper or wool-wire to detach the label.


Wait at least a week before cleaning the self-cleaning window for the first time to ensure all sealants used in its installation are fully set. Start with a rinse or hose-down with clean water and continue, when necessary, with a normal maintenance routine (see below).


During the week after initial installation and clean-down, the permanent self-cleaning coating of SGG BIOCLEAN will be progressively activated, triggered by exposure to UV light.

The length of time required to activate the Self-Cleaning Surfaces by UV rays can vary depending on the season and orientation of the glass, but in normal conditions is within a week.

When the glass is wet and small border of water droplets may appear. around the perimeter surface of the glass. This is perfectly normal.

Routine Maintenance

SGG BIOCLEAN has a special property which means the glass stays cleaner for longer than conventional glass. The more exposure the product has to both sun and rain, the cleaner it will stay, for longer. However, a number of factors affect the time it takes for a organic dirt to be naturally removed, such as the level of ambient pollution, atmospheric conditions (e.g. long periods without rain) etc.

SGG BIOCLEAN is not a '100% maintenance-free product'. Should the glass require occasional manual cleaning, carefully follow these instructions.


- A soft, clean lint-free cloth or chamois leather

- or a clean, soft non-abrasive sponge

- or a clean, non-metal window squeegee

All equipment must be kept clean. This is to prevent any dirt or abrasive materials from transferring from the equipment back onto the glass, which may scratch or damage the coating.


Clean water will normally suffice. Standard, mild glass cleaner products can also be used (visit to view a list of recommended cleaning products).

'Soft' water is best used for cleaning glass., in hard-water areas to a small amount of washing-up liquid can be used to soften water.

For the removal of stubborn marks, white vinegar can be used. Always ensure that the vinegar does not come into contact with the frame and that it is washed off the glass after application.

Vinegar is not to be used as a regular cleaning method.


Do not use any glass treatment products, or abrasive cleaners, containing silicones or abrasive particles.

Do not use any commercial cleaning products which are intended specifically for cleaning elements other than glass.

Do not use chemical products: soda, bleach, washing powder, white spirit etc.

Avoid contact with all sharp or abrasive objects, including jewellery, buckles, tape measure, razor blades, Stanley knives, scouring pads, steel wool, sandpaper etc.

Never attempt to clean off a specific mark on the surface of SGG BIOCLEAN without applying water first.

Protection during building/maintenance work

If any other works are taking place in the vicinity of SGG BIOCLEAN then protect with a clean plastic sheet to prevent any. splashes or staining from aggressive compounds (paint, varnish, glue, sealant, cement, plaster, mortar etc). This will also protect the product from abrasive or hot particles (grinding or welding sparks).
