I got the Simple Green, now what do I do to clean the belts? Tips? Tricks? With or without the buckels? Thank you

I'd try very warm water and SG 75/25 mix in a 5 gallon bucket, with the buckles hanging over the top edge.

Scrubbing depends upon what shape the fabric is in, as well as the sew on tags. Start with a soft brush and go firmer as necessary.

I just cleaned some with a carpet cleaner.

Put a thick towel under and used a scrub brush with capet cleaner. They came out nice...

I am sure the simple green will work the same way.

next set I need to clean are going to a drycleaners, buckles and all. they clean stuff with zippers and buttons, so why not?

I used liquid laundry detergent and a soft brush to clean mine, but there's no reason Simple Green won't work as well.

Used the Simple Green with warm water and hung the buckles out over a bucket. Used a medium scrub brush and rinsed several times...beautiful. Thanks and the bucket of water was filthy!

My black set was a disgusting mess that had sat for more than 20 years. I soaked them, buckles and all, in a bucket of warm water and OxyClean (@ high strength). Used the soft scrub brush and repeated once. Rinsed several times. They came out like literally like new and the buckles were beautiful too. The best part was that my manufacturer tags all came out a nice shade of white too, with no damage to the printing!
