The invention relates to the technical field of daily 
chemical products and in particular to a clean 
effervescent tablet with 
pesticide residue and 
bacteria removing effects and a preparation method of the clean 
effervescent tablet. According to the preparation method disclosed by the invention, a specific surfactant is combined with a special wet 
granulation process, so that the feasibility of the production process is ensured. The clean 
effervescent tablet has the advantages that no 
dryness or stickness is caused; the adhesion of foam to the surface of a disintegrating agent can be inhibited, the disintegration speed is increased and an effervescent effect is quickly exerted; in the disintegration and dispersion process, the efficient alkaline supplementing effect on a 
solution system is realized by synergizing a 
bacteria remover with an alkali-source supplement, fruit 
wax and 
pesticide left on vegetables and fruits can be effectively removed, and the aims of effectively removing 
escherichia coli and 
staphylococcus aureus are achieved. By using the alkali-source supplement with a special structural form, 
metal ions in the 
water body and on the surface of the vegetables and the fruits can be effectively chelated, the effects of 
softening the 
water body and chelating the 
metal ions are realized, and the deposition of 
calcium scales on the surfaces of cleaned materials is prevented; in addition, a variety of 
calcium scales or stains are dispersed, so that secondary 
pollution to tableware, the fruits and the vegetables caused by deposition is prevented.
