I'm glad to see there's still a lot of interest in the DG line. It does not get promoted really, other than by word of mouth by satisfied users. That message can get drowned out by all the hype surrounding the newest of products to hit the market. DG's stuff just plain works and is very reasonably priced...what more can you ask for? They are working on new products too, but nothing gets released unless it is up to the very high standards as the rest of the line.
These are the products I have from them and continue to use after years:
901 (a 5 gal pail)
501
105
601
AW (all of the above bought by the gallon)
221 Leather conditioner
281 Tire Dressing
271 Flat black and trim dressing (by the gallon)
471 Bug Remover (by the gallon)
481 Wax Eraser
921 Fast Clean and Shine (by the gallon)
505 Water Spot Remover
371 Odor Eliminator
451 Foaming Fabric Cleaner
681 Plastic Lens polish
751 Rain Repel
755 Nu Glass
The only product I have tried that I will not buy again is the All Wheel Cleaner. It's not b/c it was a bad product, I have just found that Zep Citrus cut 4:1 was just as effective for most jobs as the 821 AWC was. For nasty jobs, I have to break out the Megs WB or Carbrite Acid anyway. Zep is cheaper and available locally. Other than that, I have started using the OB tire dressing and it is really nice. Everything else on that list I regularly keep in stock. They all work well.
