Odor, deeply imbedded
In carpeting, upholstery, concrete and other porous materials, use Cat-Off directly
from the bottle. Pull up on the applicator cap, point the bottle at the problem
area and squeeze. Thoroughly soak the area, let dry. Cat-Off must penetrate
as deeply as the problem odor. If any odor remains, Cat-Off has not reached
the source. Repeat treatment. This kind of problem cannot be sprayed away.
Cat-Off may be used directly from the bottle as above or put into a spray bottle
and sprayed on the areas affected. Very effective when applied to the surface
of litter boxes or tomcat spray.
Rub area thoroughly with Cat-Off soaked sponge or cloth. Blot with clean cloth.
Let dry and vacuum. Although Cat-Off is a quality stain remover, not all stains
can be removed by a single agent.
Always spot test before using.
