I use a hudson sprayer to clean my tent. I mix up a batch of soap and water and spray down the all the walls, roof and floor and wipe it down with a wet towel to remove the soap solution and whatever dirt/dust/grease it may have loosened. I empty the sprayer of whatever remaining soap solution and make up a solution of bleach and water using 1500ppm as my minimum. I route my exhaust ducting so that it blows into my backyard. I pump up my sprayer, stick the wand inside the tent, set the handle to always on and close up the tent. I let it go until the pressure in the sprayer has dissipated. I'll pump it up again if the tank still has bleach but after I get it going I'll turn on the fan so that I can exhaust whatever bleach vapor is in the air and spores and mites can't hide in the fan or ducting and will kill whatever mold may form from the humid air that passes through it. Once that's done I open the tent and wipe it down with a wet towel to remove whatever bleach residue there is and let dry.
Lights and gear will get a shot of compressed air and a wipe down with a rag soaked in my 1500ppm bleach solution. Put it all back together and I'm ready to rock!!! 🤘
