What does everyone wash their PVC fittings and valves with ? Just purchased a gate valve for my bean animal and noticed that it was lubricated with some type of grease or oil. I assume this would be bad for fish
I would wipe any excess. I would not wipe where the o-rings are. That helps keep the rubber flexible and from not drying out. It helps keep the seal. I don't have facts on hand but I added more lubricant and not worried about being toxic.
