When we jet wash, regardless of purpose, we aim to remove as much residue, dirt and grime as is humanely possible. Perhaps you would like your fencing resprayed to further protect it from the elements and to keep it alive, even old timber can be rescued and given a new lease of life with the correct TLC. Perhaps its a driveway that needs re-sanding but is full of moss and weeds. It could even be a wall which needs cleaning down before being repointed, whatever the reason, we use the minimum and least harshest chemicals, we only use cold water and we ensure that we do everything in our power to protect the natural landscapes that we frequently clean in and around.
