  • Patent number: 4820450
    Abstract: A method and cleaning composition are the subject of the invention. The cleaning composition may take the form of an aqueous solution, a powder, or a concentrated powder or aqueous solution for addition to a cleaning solution. The additive includes an amine or polyacrylamide flocculant and a betaine stabilizer. When used in a detergent solution, the flocculant causes contaminates introduced into the water to precipitate and quickly settle to the bottom of the cleaning bucket. This keeps the upper part of the detergent solution clean and prevents the mop from picking up and subsequently redepositing the contaminates each time it is dipped in the bucket.

  • Patent number: 4751763
    Abstract: A mop bucket insert for maintaining a portion of a cleaning liquid contained in a bucket free of suspended solids. A platform spaced above the bottom of the bucket and side walls coupled with the platform substantially segregated solids which have settled in the compartment formed between the bucket bottom and platform, preventing suspension of these solids when a mop agitates the liquid. The platform provides a surface against which a cleaning instrument may be applied to remove solids entrained in the fibrous elements of the mop.
