For frozen paint maintain is juz normal wash thats all.
It depends the workshop use what brand matte lacquer.
All my customer after spray they only use water wash. Soap not really need to use.
Birdshit or fruit juice easy wash off
No stain left behind after clean off
No water mark stays on
Juz a pcs of cloth wipe off is clean
Thats what they feedback to me
They say easy wash easy maintain
I have confidence in my products also
As the matte lacquer i import in myself
Tested by myself then i launch to market
I also importing wax for matte finishing soon
The lacquer we use contain wax in it
Water wun stay as a pool on surface
Only can see water droplets
1 wipe water is off
Smooth surface always.
Stubborn stain can use alchol or turpintine or zippo oil to clean off
