Why vehicles can be difficult to clean
Contamination can move into seat seams, carpet, underlayment, trim, and other confined areas that are not reached by ordinary surface wiping.
Contain the affected area
Avoid unnecessary use of the vehicle until you understand the extent of contamination, especially when material may have reached absorbent surfaces.
Discuss the vehicle before cleanup
Tell us the vehicle type, where the contamination is located, and the general size of the affected area so we can discuss whether the job is within scope.
