So I’m halfway through a feature now and just started the "bloody" part. SFX and makeup have thousands of liters of blood at their disposal so it will happen, shit is going to get sprayed. What is best for cleaning your gear? Hand units, monitors, filters, camera, all of it.. pancro and lens wipes? I’m running through a couple of packs of cap-it’s a day😉 Shoot! (Pun intended😜)
In the case of thousands of liters of blood I would suggest (from the front to the back): - You can take out most of the matte boxes screws, for instance the 4 of an LMB. Then use velcro to connect the matte box to the filter stages. It's easy to take off for cleaning, quick to replace and two people can work on one thing at the same time, one on the matte box and the other one on the filter stages. Q tips are great for those corners. - Double each filter in your set, so you can take it out after the take, replace it with the other one and continue shooting while the 2nd is cleaning the other one. The only thing is that you'll have to ID them on the slate so the DIT will now which one you're using, most likely they won't all perfectly match and with the ID he can use kind of his presets for color correction. - It's hard to tell without seeing your setup, I just guess you're going handheld most of the time. So for the handles (also top handle) you could use cling film. It's easy to attach, got a good grip for the operator, it's cheap and quickly renewed. - Monitors I always cover by a shower cap and tape it on the screen, doesn't matter then if it's water or blood, it will just not hit the electronics. Same thing for the Viewfinder. Shower cap over it, if you've got time, cut a whole and put it between evf and eyepiece. - to clean I would suggest giving your filters a treat, having an alcohol bath on set, just a 2 Liter bowl where everything that's bloody goes in to get the rough stuff off it, then after I'd use pancro and lens wipes for a nice finish. - For all the hardware like handles, tripods and stuff I got a super tip from a 2nd AC last year. There's a thing from Kim wipes called "Wypall". It's cleaning tissues, but for the bigger stuff. Haven't tried it with such amounts of blood yet, but those guys cleaned so good so far, I bet they take care of your bloodshade.
On the last Halloween movie we shot in October I had to take every screw out of my mattebox and clean each piece individually with panchro. The blood they use gets really hard to clean after it drys. I still find little splatters to this day from that movie.
