Frequently Asked Questions

What surfaces can Extreme Clean Conservatory Roof Cleaner be used on?

The linked safety sheet lists glass and polycarbonate conservatory roofs, UPVC rafters, gutters, frames, skylights, greenhouse panels, fascias and soffits. Check the label and test compatibility before full application.

Is this cleaner safe for seals and gaskets?

Test an inconspicuous area and confirm compatibility with the panel, frame, seal or gasket manufacturer. Do not assume every finish or component is unaffected. Follow dilution and rinsing instructions.

Can it be used on polycarbonate without causing yellowing?

How should I dilute the product for regular cleaning?

For routine maintenance, dilute up to 1:10 with clean water. For heavier soiling or algae streaks, use 1:4, and apply neat for stubborn black lichen.

How long should the cleaner be left on the surface?

Allow it to dwell for 2–5 minutes while keeping the surface wet. Do not let the product dry during treatment.

Do I need to scrub the roof while cleaning?

Light agitation with a soft, non-scratch extension brush is recommended for stubborn dirt, but no heavy scrubbing is required.

Can I apply this cleaner with a pressure washer?

It can be applied with a low-pressure sprayer or watering can. A pressure washer may be used only for rinsing at a gentle fan-jet setting.

Will it damage nearby plants or grass?

The linked safety sheet identifies harmful effects on aquatic life and instructs users to avoid environmental release and entry into drains. Protect surrounding areas and manage runoff according to the label and safety sheet.

Is this product safe to use indoors or on enclosed structures?

It is intended for outdoor use. Always work in well-ventilated areas and avoid use in enclosed spaces without proper ventilation.

Can it remove black lichen stains completely?

Results depend on the staining and substrate. The linked sheet gives neat use for tough spots, but does not guarantee complete removal. Follow the label and test compatibility before treatment.

How much area does one container cover?

A 5 L container covers around 150 m² at a 1:10 dilution or about 40 m² when used neat. Coverage varies with surface texture and contamination level.

Is the product safe for aluminium frames?

Can I use this cleaner in direct sunlight?

It is best to clean on a cool, overcast day to slow evaporation and reduce streaking for optimal results.

Does the cleaner provide any protection after rinsing?

Yes, a hydrophobic additive leaves a microscopic water-repellent layer that helps shed rain and slows future dirt build-up.
