TL;DR Rinseless concentrate from the company that invented waterless washing · Boeing BSS7432 certified, but no GHS SDS is on file for this specific P/N 555 formula and the community track record is still thin.
Mix 1 oz per gallon, dunk a microfiber, wring, wipe a panel top-down, then dry with a separate towel. Aero Cosmetics holds Boeing BSS7432 certification and has been making waterless products since 1987 · that aerospace pedigree is real. The P/N 555 rinseless concentrate is a newer, distinct formula from the brand's RTU 777 product; as of the review date, no independent forum discussion specific to 555 has been found. The brand's multi-polymer encapsulation claim cannot be independently verified at this scoring round.
Best fit: buyers who trust aerospace credentials as a quality proxy and want a concentrate format. Skip it if you need community-validated scratch safety on dark paint before committing · the 555 formula is thin on that evidence. For a rinseless concentrate with deep forum history, Optimum No Rinse is the established benchmark.
No GHS Safety Data Sheet is available for P/N 555. Health is held at 5.0 here because the manufacturer hasn't published an SDS, not because the chemistry is known to be unsafe. Hazard codes cannot be confirmed from any available source. The rinseless format eliminates the hose rinse: chemistry stays in the microfiber rather than going down the storm drain.
Mix 1 oz per gallon of water for rinseless or waterless wash use. The 16 oz bottle makes 16 gallons of wash solution · enough for roughly 16 full wash sessions. The same concentrate can be used as a clay lubricant at the same ratio.
No. The P/N 555 'Rinseless Car Wash and Wax' is marketed as a 'new formula' with a multi-polymer blend for improved encapsulation. Aero Cosmetics has been making waterless and rinseless products since 1987, but 555 and the RTU 777 are different products. No SDS for the P/N 555 formula has been located as of the review date.
No GHS Safety Data Sheet is available for this product (P/N 555). Without a GHS SDS or confirmed ingredient list, the formula's hazard profile cannot be assessed. The site applies a baseline health score of 5.0 and marks the product 'NO SDS' until a compliant SDS is located.
As of the review date, the 16 oz listing (ASIN B0BKQYSBFD) shows 'Currently unavailable' on Amazon. The gallon size is available directly from washwax.com, though it was listed as backordered at the time of review.
