Upholstery care codes and portable spot cleaners
Last checked 2026-10-03.
Look at the care tag before cleaning upholstery with a portable spot cleaner. Per the manuals of the BISSELL Little Green 1400B and the Hoover CleanSlate Plus, "W" and "W/S" fabrics may be wet-cleaned; "S" (solvent or dry clean only) may not, and BISSELL adds "Dry Clean Only". A missing tag, or a code the manual does not address such as "X", is unknown: check with the furniture maker or dealer, and test a hidden area first.

Which formula goes in which machine
| Formula | Mixing | BISSELL Little Green 1400B | Hoover CleanSlate Plus FH14050 | Buy |
|---|---|---|---|---|
| BISSELL Little Green formula 32 oz | diluted in the machine per its fill lines | yes, per the manual | no: the manual names another brand | Amazon › |
| BISSELL Little Green formula 60 oz | diluted in the machine per its fill lines | yes, per the manual | no: the manual names another brand | Amazon › |
| Hoover Oxy solution 32 oz | pre-mixed, per its listing ("comes pre-mixed so you can simply pour and go"); the machine manual's 5 oz to 35 oz chart is for Hoover concentrate, so it is not applied to this solution | no: the manual names another brand | yes, per the manual | Amazon › |
Each manual names its own brand's formula; a bottle that says it suits "all leading" machines does not change what a manual allows. Using another formula is outside the manual.
Kinds of claim on this page: fabric codes, formula rules, tank sizes and what is in the box are product evidence from each machine's manual or listing (read 2026-10-03); which formula goes in which machine is a compatibility statement, only as the machine's manual gives it; words such as "removes stains" or "eliminates odors" are a manufacturer claim and are not repeated as findings; anything no source states, including hose and cord reach, is unknown.
We tested nothing: no stain, odor, drying or noise measurements. Nothing here says a machine or formula removes a particular stain, sanitizes, removes allergens or dries faster. A machine being allowed on a fabric code is not permission to wet-clean every sofa: check the care tag, test a hidden area, and follow the manual. Never mix cleaning chemicals.
The two machines: BISSELL Little Green 1400B vs Hoover CleanSlate Plus. Formula cost: formula cost.
