Cement benches can be subject to constant exposure to outside conditions which can make them dull, dirty, and rusty. Stains and mold on these benches are not uncommon sights either. This is why you need to clean them regularly.
Just like cleaning cement curbings, cleaning cement benches is easy with the right materials and methods, which I’ll be showing you. Before cleaning your cement bench, you have to first prepare the bench for cleaning.
Let’s get right into it!

Getting liquid stains off your cement bench can be tough but the methods explained above work well in getting rid of them. In case you tried these methods and they didn’t work on your cement bench, however, you should try this.
1- Corn star/clay cat litter

Cement Bench Care & Maintenance
You definitely need to be using the following tips to prevent the possibility of you having to replace your cement bench in near future.
1- Clean your cement / concrete benches regularly, at least once a week.
2- Spills should be immediately cleaned up so they won’t be absorbed by the cement bench as it is quite porous in nature.
3- Avoid using caustic acids to clean your cement bench, because these can change its structure and also etch the surface.
4- Never expose the cement bench to harsh chemicals which may destroy or leave stains on the surface or even crack the bench. Always read the label of the product to determine its suitability for cement benches.
5- Do not use metal brushes on the cement benches as the iron/metal fibers can leave residue in the cement/concrete (as it is porous), which will rust later on.
6- Always remove leaves and other debris during the fall season and after storms. These wet leaves will retain moisture in them and will cause mold and mildew on your cement benches.
Cement benches are durable and need low maintenance. However, just like most other surfaces which are exposed to outdoor conditions, they need cleaning.
Whether they are normal stains or grease stains or mold & mildew that you need to clean, the methods shown are tried and tested and REALLY WORK. So you should get to work now.
