Artillery Fungus

[RobnTennessee]

I just purchased a 2018 metallic grey Rav4. On top of the car are several black spots, which after researching a bit, it's artillery fungus. How do you clean it off? It has a rough feel to it.

I'm not familiar with that fungus, but a quick Google search infers to try soap and water first along with a pressure washer; vinegar may also work. If they've been on there a while, which it sounds like, the article said the spores are sticky so I would try TAR.

Hi Robert,

I have had the unfortunate pleasure of dealing with Artillery Fungus twice and in both cases White Vinegar is what I used and a sponge to get the remaining spores off the vehicle.  It takes time and effort to get all the spores removed that don't come off with the pressure washer, but they come off.

I'll be tackling that in the morning.

Hopefully all went well with your fungus removal.  Keep us posted on the outcome.

It went very well. I used a sponge, car shampoo and pressure washer, got all of it off and no visible signs that it was ever there. Thanks for the advice!
