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 big towel. 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 spores and mites can't hide in the fan or ducting and I can exhaust whatever bleach vapor is in the air. Once that's done I open the tent and wipe it down with a wet towel to remopve 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!!!
