Hello

So some numpty went and used exhaust sealant all over the CAT (Catalytic converter) and on some of the parts that are upstream of the CAT.

What is the best way to remove this sealant to make it safe for the CAT and O2 sensors?

Thanks

Which exhaust sealant isn't sensor safe? Do you actually mean silicone sealant?
