What's the best way to softwash uPVC fascia, soffit, gutters & painted surfaces? (video)
We are frequently asked if Benz Lightning Cleanze is suitable for cleaning uPVC – such as fascia, soffit, gutters, doors and windows – and painted surfaces.
The answer is Yes, it does an excellent job in only a few minutes. And at only 10-20:1 dilution.
Most of the time only one spray coat is needed and it's a simple "spray on – rinse off" process.
Quick tips:
- If the uPVC is particularly dirty, gently agitating the treated surface with a soft brush can significantly speed up the cleaning process. And 10:1 dilution is usually advisable.
- In very hot weather a strong solution of LIghtning Cleanze can sometimes produce a temporary discolouration. This usually fades in a few days but can be prevented by a) treating at no stronger than 10:1 dilution b) pre-cooling the surface with a light water spray c) working at the coolest time of day.
- If you have to treat uPVC in hot weather it can be a good idea to increase the dilution to 12-20:1 or more. This is because the chemical becomes more reactive when exposed to heat, meaning that the cleaning effect of 12-20:1 in hot weather can be similar to 8-10:1 in cooler weather.
Note: Ben refers to "Blackwash", which was an earlier name for Lightning Cleanze. The product is the same.

PS: Self cleaning glass was developed for aeroplanes where the continual movement helps the self-cleansing action. Houses are stationary and because of this it apparently does not work as well. We are receiving reports that most customers are disappointed with the effectiveness of self-cleaning glass. It still needs regular cleaning, just not as regular as regular glass.
