Dust in the groove of the sash. hard. mud. It is impossible to suck it with a vacuum cleaner. Wipe with cloth. Wet cloth becomes mud.
It is not beautiful. High pressure washer is effective. However. I dont have it.
I decided to use “pressurized cleaning spray”.
What to prepare. It is “pressurized cleaning spray” and “plastic bottle”.
High pressure washer uses electricity. This does not use electricity. I could use it easily.
I connected a thin pipe to the main unit.
The length of the pipe. Length for 1.5 liter PET bottle. If you use a 500 ml plastic bottle, cut it.
I put water in a PET bottle and installed it.
I compressed the air by pistoning the knob.
A sign of air compression completion. That’s when the knob got stuck.
injection. Two types of straight and spray. It is switched.
I chose straight.
I fight against muddy sash.
I started straight firing.
Was there a change in the sash after injection?
The sash mud has fallen. There was also mud which resisted partly. However. The mud became beautiful without rubbing with a toothbrush.
important point. The momentum of water is strong. Splashes splash. Put a towel around the sash. This is necessary. There is a towel. It keeps the room from getting wet. Beyond imagination. The strength of its hydraulic pressure. I have wet the room. next time. I always put a towel.
I used a spray.
Citric acid was mixed with water. I used it for the sink.
I was surprised. The sink cleaned up.
Especially. The water service was really beautiful. It is shining.
I used a PET bottle of tea. PET bottles are better for carbonated drinks. The plastic bottle of tea bulges and deforms when pressurized. It fell down.
I used it as a carbonated drink bottle. Bottle does not deform. The water pressure is higher than the tea bottle.
