Hydrotek has a surface cleaner with a dump valve to drop the pressure and speed of spinner bar. It actually works well on wood in certain situations with no striping or damage.
Start with the valve open and slowly close it to get just enough pressure to do the job. It takes finess and attention to detail to make it work. I did a test deck last year - half with wand, half with cleaner then sealed it. I couldnt tell the difference. |
