Adam's Polishes All Purpose Cleaner vs P&S Detail Products All Purpose Cleaner

Adam's is the only product here that describes what the cleaner does at full strength and what it does diluted, and names the surfaces for each. P&S makes the same range of claims in trade sizes with a longer surface list and a biodegradable formulation.

The only bottle here that tells you what it does at full strength and what it does diluted, and which surfaces belong to each.

• Describes full strength use for cutting heavy grease and buildup, and diluted use for body panels, interior components and leather.
• Explicitly described as dilutable for delicate surfaces, which frames dilution as a control rather than a saving.
• Sizes from 16 ounces to five gallons, so it works for a single car or a fleet.
• The brand states it is safe for use in full sun while recommending cool surfaces and shade, which is a useful caveat rather than a blanket claim.

• No dilution ratio published for any of the uses described.
• No pH figure given anywhere on the page.
• Heavily dyed neon yellow and citrus scented, which some people would rather not put on a headliner.
