CLEANING TIPS FOR TOUGH STAINS ON YOUR ALUMINUM
If the stains seem stubborn, prefer a mixture respecting the following ingredients and their respective proportion:
1/3 cup of detergent,
1/3 cup of bleach, and
1/3 cup of trisodium phosphate (which is a very powerful cleaner and degreaser).
For those interested, this product is available in a biodegradable version.
If the surface to be cleaned is oxidized, take care to gently scrub it with a very fine steel wool (from top to bottom). Avoid circular movements at all costs, as these will scratch the coating.
CLEANING TIP FOR TOUGH STAINS ON YOUR VINYL
For tougher stains, mix 4 liters of water with 1/3 cup of Hertel (or a comparable cleaning product) and 2/3 cup of trisodium phosphate to effectively clean the coating with the help of a soft-bristled brush.
To clean surface mold marks, the process will be different. Specifically, it is desirable to rub the stain with a soft-bristled brush and diluted bleach. If the stains are darker, combine 1 liter of bleach with a degreaser/cleaner (2/3 cup) as well as a smaller amount of all-purpose detergent (about 1/3 cup).
FOR BRICK CLEANING
The first option available to you is the use of a pressure washer. However, note that the jet should never be directed at the mortar joints, as they will crumble. Ideally, it is recommended to hold the device about 60 centimeters away from the wall.
To get rid of a stain, the use of caustic soda detergent is the preferred option.
