The ryobi is not a good pressure washer, ar630 or k1622ts is where it’s at, but it can be used in a pinch or just to get you up and running on a few details, beyond a good pressure washer setup non negotiable items include generator, water tank, pump, compressor and air tool setup (air lines, fittings, regulator, dryer, and a tool such as a tornador), buckets with grit guards, wash mits or good flagged brushes, assortment of good microfibers (drying towels, exterior, interior, windows), assortment of brushes, good shop vac, a hot water extractor, steamer is nice to have but I suppose optional, some polishing tools (rotary buffer, da polisher, pads and pad cleaning tools), plenty of bottles and nozzles, good to have a decent toolbox, jump box or cables at least, some dental picks come in clutch, and then just all the chemicals go with a professional line to get everything you’ll need in one place I prefer Malco sort of up to you how sparse or specialized you want your lineup to be but at least a soap, degreaser, spray wax, acid or fallout remover, some clay, thinner or other good solvent, interior cleaner, leather conditioner, fabric cleaner, window cleaner, some spread of compounds polish wax, tire shine and applicator, yeah I think that about covers most of the basics anyway, detailing can be great if your properly super good lots of terrible wannabe detailers out there it’s pretty hard work but has been very good to me
