The best way of removing paint without chemicals involves using cleaning devices.
These cleaning devices include soda blasters and pressure washers.
Apart from these devices, home remedies can also help you remove paint. You can use white vinegar and your liquid detergent soap.

Soda blasting is one of the most environmentally friendly processes for removing paint.
- They are practical and work well with the different types of paint.
- You also need to get the right kind of soda blaster; you need to choose one that can work well with both industrial grade and regular sodium bicarbonate.
- A soda blaster works similarly to a power washer, and this means that you need to spray the mixture onto the affected area directly.
- Then, you will need to let the mixture dry for a couple of minutes.
- Also, just like power washing, the soda mix is applied using a specialized hose.
- Since the application method is like this, there is a high chance that the surrounding areas will get sprayed too.
Thankfully, soda blasting will not damage the surface of the concrete.
