Hi - my Electro-Groom seems to have suffered from our area’s humidity and has developed a couple of rust points. It’s not damaged and is only a few years old. Does anyone know where I can buy touch-up paint for it? I’m striking out in my online searches.
Did you contact the maker directly (website is electriccleaner.com)? They have been very helpful in the past when I’ve had questions about mine.
per their web site
The company feels strongly about the design and construction of these units perfected with over thirty years of experience in design / production of grooming equipment. Should you experience a problem with equipment, return the unit promptly and we’ll repair it.
Please contact one of our dealers or call the factory direct at (800) 456-9821 for assistance with parts or repairs.
I have but had not heard back. I’ll reach out again.
Thanks! Sending it away is a scary thought - living without my horse vacuum for weeks?!
